During the this past 12 years of my weight-loss maintenance, I’ve been collecting data about my food and weight. This provides me with a great deal of personal information, and that data tells me that … over the years … my weight is continuing to creep upward, even though I keep reducing my calorie intake.

I find this fact very annoying, as well as perplexing.

Until I was faced with this personal information, I believed what our Culture teaches:  “If Fat people cut back on their food intake enough to reach a “normal” weight, their bodies will become like the bodies of “normal” people. To maintain that weight loss, they need to eat more than they did to lose the weight, but not go back to eating as they did previously: in a gluttonous manner.”

Essentially, I thought that you diet down to your goal weight number; cross the finish line; and from that time on you will maintain your weight-loss by eating like normally thin people do.

This is NOT what has been happening for ME. So, I began wondering why? What’s going on?

I spent a lot of time studying books, and articles, and research about this issue, and learned that as a “reduced obese” person, what has been happening to ME, personally, seems to fall within the theories of Set Point, and Biological Adaptation. 

My History

I’ve spent my lifetime dieting, from my youth into my old age. I’ve lost, and regained, hundreds of pounds of fat.  About 25 years ago, at age 48, I had an open RNY gastric bypass surgery, which - at the time - was still considered experimental.  This forced me to eat in a way that dropped my BMI from a 52.9 BMI = Stage 4 - Super-obese, down to a  31.4 BMI = Stage 1 - just over the border of obese.  After a few years I began actively dieting again in order to avoid a rapid regain.

About 13 years ago, around age 60, I was back up to a 38 BMI = Stage 2 -Severe obesity. I began logging my food and daily weight into a computer software diet program.  I begun losing weight, and about 16 months later, in January 2006, I reached my goal of a 22.5 BMI = in the middle of the "Normal" weight range.

During the 12 years since that time, now almost age 73, I’ve continued using a computer program to log my food and daily weight.  As a result of that effort, I’ve maintained my weight at-or-near a BMI range of “normal”. I now also have 13 years of records showing my personal daily food and weight data.

1993 Weight-Loss 

About 25 years ago, I actually experienced an open RNY Gastric Bypass surgery, after which I ate tiny amounts for many months,.... estimated amount is from 300 to 600 calories daily. “Cheating on that diet" was physically impossible for me.

The calculations in this chart demonstrate that one could reasonably assume that during that 30 week period in 1993, my body’s estimated average daily calorie burn was somewhere around 2100 calories.

2005 Weight-Loss

About 13 years ago, I dieted from 190 down to 120 lbs over a 67 week period. At that time all of my daily food was logged into a computer program, which demonstrated that my daily average calorie intake was 1224.

The calculations in this chart demonstrate that one could reasonably assume that during that 67 week period in late 2004 & 2005, my body’s estimated average daily calorie burn was somewhere around 1746 calories.

12 Years of Maintenance of Weight-Loss

Here’s a chart of my past 12 years in Maintenance.  It shows my total daily calorie amount for an entire individual year, averaged out.  It also shows my total daily weight amount for an entire individual year, averaged out.  It also includes the lowest recorded weight for each individual year.

One would expect that my average yearly weights, and my average calorie intakes would be directly proportional, in that as my average calorie intake decreases, my average weight would also decrease.  Instead it appears that those values are inversely proportional: while my calorie intake has been decreasing, my weight has been increasing.



Even with my detailed records, my exact current total calorie burn still involves a lot of guesswork, but at this point, it appears to be somewhere around 25%-or-more Below the Average BMR for a female my same age, size, and activity level.  Since I am a small, inactive, elderly female, that is a Very Small amount of food. Frankly, eating little enough for maintenance is quite hard to do, and I’ve been finding additional Weight-Loss to be nearly impossible.

To provide perspective:
 BMR (basic metabolic rate - without activity) according to Mifflin formula,
       1058 calories for an AVERAGE 60 year old female, weighing 125 lbs
       1008 calories  for an AVERAGE 70 year old female, weighing 125 lbs

Calorie Error

When looking at these ongoing calorie numbers, the first thing that comes to mind is unintentional calorie error. 

An important relevant fact is that these foods and amounts eaten were recorded at the time they were eaten, therefore the calorie counts provided are not based on inexact memories.

Calorie counting is never an exact science, and at the low calorie numbers required by my metabolic rate, an unwitting daily 10 to 20 percent error could account for a 100 to 150 calorie deviation from the actual amount.

However, another important relevant fact to recognize is that during all of these past 13 years I weighed and measured and recorded my foods in the same way.  Therefore, any inadvertent calorie error due to my methods of measuring and counting would have been consistent over time so it is unlikely to account for the calorie average deviations shown over time. 


Correlation is Not Causation

The common Scientific Belief is that that weight-loss is caused by a calorie deficit, and weight-gain is caused by a calorie surplus.  I feel certain that this is true.

Facts:

• It is a fact that I was previously morbidly obese, and that I lost down to a normal weight.
   
• It is a fact that my weight has been going up during my past 12 years of maintenance.
  
  
• It is a fact that the calories of my food intake has been going down during my past 12 years of maintenance.
  
  
• It is a fact that I am older now than I was when I originally lost the weight.
  
  
• It is a fact that I am less active now than I was when I originally lost the weight.
  
  
• It is a fact that during the past 4 years my recorded calorie intake has been less than the BMR calories for an AVERAGE 70 year old 125 lb female.
  

Correlation is not causation. Each of the above mentioned facts are variables, and there appears to be a correlation between these variables, however, this does not automatically mean that the change of one variable is the cause of the change in another variable.  Causation indicates that one event is the RESULT of the occurrence of the other event. .. That one thing CAUSES the other.

I am able to REPORT here what I’ve seen happening with my body, but I am not able to actually KNOW what is causing this to happen. I’ve thought about this issue a great deal, and I’ve done as much research on the issue as has been possible for me. This has led me toward certain general opinions and beliefs about the subject, but I have no True and Ultimate Answer to what, for ME, is a genuine personal problem.  I also have no Ultimate Answer for other people who appear to have a similar problem.

The following statements by obesity specialist, Dr. Freedhoff  M.D. make a great deal of sense to me.
 
He says that:

Physiologically, Plateaus don't exist. Unless it's a temporary trick of the scale, . . . if you're not losing, either you're burning fewer calories than you think; you're eating more than you think; or some combination thereof. 


There's no Plateau, but there IS such a thing as a "FLOOR". If you've truly stopped losing weight, there are really only two questions you need to ask yourself.

    1.    Could I happily eat any less?
    2.    Could I happily exercise any more?

If the answer is "yes" then you can tighten things up, but If the answer to both is "no", there's nothing left for you to do. 

This is because if you can't happily eat any less and you can't happily exercise any more -- then it's unlikely that this will ever become part of your permanent behavior. 
 

Here is my ongoing personal solution to the problem addressed in this article.
Work to ACCEPT the reality of the situation while, at the same time, do my best to FOLLOW THROUGH WITH DOING THE INDICATED THINGS which are required for long-term maintenance of my large weight loss.

It is what it is.

I created a Weight Range Maintenance Chart
in order to make my maintenance weight goals clearly visible. 
This is my Current Chart. 

Here is a scale photo of my current weight. 

I have been successfully maintaining a very large weight-loss for many years.  You can find my history in the ABOUT ME section which contains a great many links to detailed weight and calorie charts.

I reached my goal weight of 115 pounds in January 2006, and since that time I’ve been making ongoing, consistent, diligent efforts to maintain my weight near that number.

I work to keep my weight within a certain number range, rather than at an individual “goal weight” number. 

I find this necessary because my body has frequent large weight bounces due to salt/water/waste issues. 

Despite my best efforts, during any one-month period, my daily weight tends to bounce back and forth inside a 5 to 8 pound range.

For the past 12 years, I’ve been able to keep these bounces between 115 and 135 pounds. 

On occasion however, my weight has BRIEFLY been as much as 10 pounds below and 5 pounds above that basic bounce range.

The yearly weight chart posted here shows my very lowest yearly weight during each of the past 12 years.

In order to demonstrate that the increases in these yearly lowest weights were NOT due to periods of inattention or a lack of effort, I’m also posting a corresponding yearly calorie chart showing my average daily calories during each of these passing years. 

I’ll be writing more about this issue in an further article on the subject of Biological Adaptation to Weight Loss and Maintenance.

My current Weight Range Maintenance Chart shown at the top of this article is a modification and simplification of this previous chart. 

During my 12 year maintenance period, although I’ve kept the Basic weight-range maintenance chart format, I’ve made several modifications to it.

This article "hits the nail on the head" in the way it accurately describes my own personal experience, as well as what I’ve witnessed for years while watching the experiences of others.

It contains one of most accurate analogies for Weight-loss and Maintenance that I’ve ever heard.

Some might find it depressing, but here in my 8th year (now starting my 12th year) of maintaining a very large weight-loss, I find it encouraging and positive to hear a medical professional, who is an expert in obesity, speak the unvarnished Truth.

Despite the fact that this Truth is rather unpleasant, and isn’t something we’re ever going to hear from Marketing Interests… (which includes most doctors and nutritionists) …. Facing it, Understanding it, and Accepting it, can be very helpful.

Running Down the Up Escalator 
                 By Dr. Ayra Sharma, M.D. (a Canadian Obesity Specialist)

One of the games I used to play as a kid was to run Down the UP escalator.

To get to the bottom, I had to run faster than the escalator was moving up. If I ran any slower, the escalator would gradually but steadily take me back to the top.

In fact, even to just stay half-way down, I’d have to keep running at about the speed the escalator was moving up. If I stopped running even for a second, I’d be moving up again.

As you may guess, I am using this analogy, to illustrate the challenge of losing weight and keeping it off.

The escalator represents all the complex neuroendocrine responses to weight loss that will always want to take you back to the top – the only way to reach the bottom or to even maintain your place half-way down is to keep running.

Alas, in real life, the weight-loss escalator is even trickier. For one, there is no real bottom – i.e. no matter how fast you run, you will never reach the bottom and be able to simply get off. No matter how far down the escalator you manage to get, you are still running on the escalator and it will keep moving you back up to the top the minute you stop running.

But things get even more depressing, because, the further down the escalator you get, the faster it runs. This means that the further down the escalator you manage to get – the harder you have to keep running to just stay where you are.

Or, in other words, when you start from the top, the escalator is running relatively slowly and you may easily manage to get down the first 5 steps. But as you go down, the escalator picks up speed and so, if you just keep up running with the speed you started at, you may not even manage to hold your place 5 steps down.

And, to get to 10 steps down, you’ll definitely have to speed up – unfortunately, with every additional step you manage to make your way down, the escalator moves up even faster.

By the time you manage to get down 20 steps, the escalator is moving upward so fast that it is all you can do to just try and not be carried back up.

Depressing?

If we could only find a way to slow down the escalator. Or even better, if you could only get to the bottom and get off!

Alas – that is not how our bodies work.

Yes, for some people the escalator moves more slowly than for others – this is why they find it easier to run down and it takes them less effort to maintain their position half-way down. Others have to fight harder to get there and for others, the escalator simply gets too fast, eventually carrying them all the way back up – no matter how hard they try.

Bariatric surgery and obesity medication can help slow down the escalator or rather, prevent it from speeding up quite as fast as you try to run down. This is why you can maintain a lower spot on the escalator with the same effort as before – but go off your meds or reverse the surgery and the escalator speeds up again only to carry you back all the way to the top.

Why is the escalator analogy important to understand?

At this point I want to add a couple of important points to this analogy.

Firstly, it is important to remember that whatever took you to the top of the escalator, if not addressed, will make the descent even harder (if not impossible).

In the simplest case – to use an analogy that a reader sent in – imagine trying to run down the escalator on one leg – it’s going to be so much harder than with two legs. So if arthritis in one knee took you to the top of the elevator in the first place, trying to get back down while your knee is still killing you is going to be so much more difficult than if your knees were OK.

Similarly, if depression or binge eating took you up the escalator, trying to get down that escalator while still depressed or still not in control of your eating is going to to be so much harder than if these problems were resolved.

It may help to think of whatever took you to the top of that escalator as additional baggage that you have to lug along as you try to run down – the heavier the bags, the harder it is going to be.

As readers will realize, those excess bags could be anything – from a genetic predisposition, to medications that you might be on, to lack of sleep, to high stress levels, to intimate saboteurs, to relationship issues, to loneliness, to body image issues, to childhood trauma – the list goes on and on….

This is why it makes a lot of sense to first deal with what took you to the top before beginning your journey down that up-escalator.

Clearly, simply jumping on that escalator without first dealing with the underlying problem will make losing weight and keeping it off so much more difficult - remember, running down the escalator with no baggage is already hard enough

But, even if the underlying problem is dealt with – you will still be trying to run down the up-escalator – that unfortunately will never change – it will only get somewhat easier the less baggage you have to carry.

But why does the escalator move up in the first place and why does the escalator analogy have important implications for how we address obesity treatments?

Why use the escalator analogy at all? Why is the escalator moving up? Why does it get faster as you get further down? And why is there no bottom, where you can simply get off?

Let’s start with the upward moving escalator – most of us are on it to start with as most of us tend to gain weight with age – unfortunately, some people faster than others. Very few of us manage to keep our teenage weights into late adulthood. There are many reasons for this – for one, our metabolism “slows down” as we get older, so do our levels of physical activity. Then there are other drivers of weight gain that tend to accumulate as we get older – stress, lack of sleep, arthritis, medications, to name a few. This means that for most of us, to not be carried higher on that escalator, we already have to take the occasional step down – the faster our personal escalator is moving up, the more effort we will have to put into simply “marking time”.

But that’s the easy part (preventing initial weight gain is always easier than treating obesity). To lose weight, you have to actually start moving down the escalator faster than it is moving up. Depending on how fast your personal escalator is moving up, the more effort this will take. The tricky part comes when the escalator starts speeding up as you make your way down – this is what is often referred to as the “starvation response” – a complex series of metabolic and behavioral responses aimed at preventing further weight loss and promoting weight regain.

In previous posts I have discussed some of these factors – leptin, ghrelin, sympathetic nerve activity, body temperature – the net result is that as you get lower down on the escalator, the fewer calories you need and the greater your hunger and appetite gets. This is why, keeping weight off gets harder and harder rather than easier and easier the more weight you lose. (Many people think that if I can only lose the first 20 lbs, losing the next 20 will be easier – that is almost never true).

Finally, why is there no bottom where I can simply get off? This is because based on the “setpoint theory” (which is actually far more than just a “theory”), your body always wants to get back to its highest weight (or back to the top of the escalator). Unfortunately, from everything we know about weight management, there is no “cure” for obesity – meaning you will always have to continue doing whatever it is you did to lose the weight to keep it off.

As I noted in my previous post, anti-obesity medications or surgery may make keeping weight off somewhat easier, but they do not “cure” obesity – stop your medications or reverse your surgery and your weight comes right back. This appears to be a rule in weight management – when you stop the treatment, the weight comes back (the same goes for “diet and exercise” as a treatment).

Although depressing, I do hope the escalator analogy is helpful in understanding how weight management works, why keeping weight off is so difficult, why very few people can ever hope to reach and maintain their “dream weight”.

Anyone, who promises you anything else is simply not being honest.

No doubt we need more effective treatments for obesity and perhaps one day we may even find a “cure” – till then, we’ve got to work with what we have.

 I’ve experienced a lifetime of dieting in order to avoid, and to end, my obesity. I always thought that: if, and when, I got to normal weight, and managed to stay there for 5 years, by then my body would adjust to being normal size, so that eating only what my body needed to maintain my weight-loss, would become more “natural”, and therefore be less difficult.

This has not been the case.

Here in my 8th year, (now working on my12th) I am still running Down the Up escalator, and the past several years, that escalator HAS been speeding up. Maintaining my body at a normal weight is harder now in my 8th year (now 12th year) than it was the first two years after arriving at my goal weight. … and it was NOT easy then.

Nevertheless, I am committed to continue.

NOTE:  DietHobby originally posted this article on 7/7/2013, and I'm bumping it up for new members.

Treating Dieting as a Hobby (see: ABOUT ME) involves the ongoing task of finding or creating ways to keep myself interested in detailed issues involving Weight-Loss and Maintenance, as well as watching how MY own body responds to those various issues.

Here at DietHobby I sometimes share my personal weight and calorie numbers, along with Tactics that I’ve used to help me in Maintenance. These past articles showing my weight and calorie history can be easily located under BLOG CATEGORIES, Status Updates.

Yesterday I posted about my Summer Experiment 2017.

Collecting, recording, and analyzing detailed personal data has helped me lose weight and maintain that weight-loss.

For the past 13 years I’ve been logging all of my daily food intake into a computer food journal which provides me with a calorie count.  I’ve also been using a scale to see my early morning weight, unclothed, immediately after urination, which I record immediately.

As part of my long-term-weight-loss-Maintenance journey I use various charts to track my progress. Although each chart uses the exact same weight and calorie information, I’ve found that charting that information in different ways helps give me new viewpoints which sometimes results in additional insight.

Bounce Chart

My body’s daily weight tends to Bounce up and down quite a lot.  In my weight-loss phase I created a table that I call a “Bounce Chart”, and during a specific time period, I make daily entries to a specific chart in order to track the range of my daily weight deviations. 

The 98 Days of Summer “Bounce” chart shown here covers the 98 day time period between Memorial Day and Labor Day 2017. It shows my starting weight was 133.2 and my ending weight was 132.0.  So, this shows that I had a net weight loss of 1.2 pounds for the entire summer which involved a 9 pound “Bounce Range”. 

During that 98 day period, I ate an average of 662 calories per day. 1st third of the summer, my calories averaged 624 per day; 2nd third of summer, my calories averaged 654 per day; 3rd third of summer, my calories averaged 705 per day.

Weekly Results Chart

This “Weekly Results” chart shows my Monday morning weight along with my daily calorie average for the prior week.

It covers the 19 week period from April 17, 2017 through September 4, 2017, showing the ongoing connections between my weekly weight and my daily average calorie intake.

This chart shows that during this time period, my net weight loss was 1.2 pounds, with a 19 week calorie average of 684.


Online chart from TrendWeight

The Chart below is from the website: “TrendWeight, Automated Weight Tracking in the Style of the Hacker’s Diet .“

It provides a graph showing my weight Trend Line  from April 17, 2017 through September 4, 2017 together with my actual daily weights.

This shows that on this current date, my actual weight is trending at 133.1 pounds.

Like most online calculators, the TrendWeight chart relies only on weight input, and makes assumptions about the calories of one’s food intake based on the commonly used metabolic formulas such as Harris Benedict or Mifflin. 

I input 120 pounds as my goal weight, and took it’s lowest weight-loss option, which was to lose ½ pound per week.  Based on that data the program told me that my body is eating 174 more calories than it is burning, and that to lose ½ pound a week, I need to eat 424 calories less per day.

My daily calorie average for the entire Trend Weight time period was actually 684 calories, and based on my ongoing weights, according to TrendWeight’s metabolic data, my body’s current total metabolic burn is 510 calories.  

 Furthermore, TrendWeight tells me that in order to lose ½ pound per week, I will need to subtract 424 calories per day from the amount that I am now eating.  Subtracting 424 calories from my average calorie intake of 684 results in a recommendation to eat a daily average of only 260 calories daily in order to achieve a ½ pound weekly weight loss.  

The Realities of Life

In previous articles I’ve spent a great deal of time discussing the issues surrounding the mathematical Metabolic formulas, including the fact that they are all based on AVERAGES; that a 15% deviation up or down is normal while there are some people (outliers) whose numbers are FAR different than the group number. 

At present, most experts consider Mifflin to be the most accurate of these formulas.  To keep things in perspective, Mifflin gives the average 72 year old, 5'0" tall, female weighing 130 pounds a BMR of 1016 calories. When sedentary activity is included to that number, the average daily caloric maintenance requirement is 1219.

One of the leading obesity researchers, Dr. Rudolph Leibel of Columbia University, says that a “reduced obese” person’s metabolic burn will normally be about 15% less than the metabolic burn of a person (of the same height, weight, age, and activity level) who has always been a “normal” weight.  Also, I recently saw a medical obesity specialist that I respect say that he’s occasionally seen deviations 25% lower than the average Mifflin BMR. 

So, if we assumed the average "normal" weight person of my size and age would have a BMR burn of 1000 calories, a 25% reduction would be 750 calories.  As there are different levels of sedentary activity, a sedentary metabolic burn of 1100 calories would not be unreasonable, and a 25% reduction would be 825 calories. 

Calorie counting is never an exact science, and at these low numbers, an unwitting daily 10 to 20 percent error could account for a 100 to 150 calorie deviation.  This could bring an outlier’s maintenance calorie burn to around 675, which is where … evidentially… my calorie burn has been trending.

Here’s an online chart graphing
my Average Weekly Weights over the past 8 ½ years.

This chart reflects that since 2013, I’ve had several successful weight drops down into the low 120s, but even though during the past 4 years my daily calorie intake averages totalled less than 1000, my body has been unable to maintain those weight-losses long-term.

The right half of this chart involves weights from the high 130s to the low 120s … a bounce range of around 15 pounds or so. 

I think it is relevant to point out that I diligently and consistently worked at dieting for weight-loss and maintenance during ALL of this time period, and the ongoing Ups and Downs shown in the right half of the chart can NOT be attributed to periods of inattention or ongoing periods of "overeating".  The drastic weight drops involved a drop in glycogen, salt, water, & waste due to several weeks of radical very-low-calorie diets  of around 200 to 300 calories.  Many of the weight increases reflected the return of that glycogen, salt, water & waste when my calories increased to an average of between 700 and 1000 calories. 

For an understanding of the kinds and amounts of food I normally eat, look at the photos of meals I’ve recorded in RESOURCES, Photo Gallery section, under the heading Petite Meals.



In Summary

So, what can a reduced-obese person who has metabolic numbers like I have, do?

I feel certain that additional exercise is not part of a solution for me. Almost 12 years ago, when I got to my original goal weight of 115 pounds, I was 60 years old and physically able to be more active than I am now. Furthermore, I have spent my 72 year lifetime as a sedentary person whose favorite outdoor activity is to go back inside.  When considering my age, my current mindset and physical limitations, there is very little I can do to change my current activity level. The small amount of additional exercise I might be able to tolerate would increase my hunger but do very little to increase my calorie burn.

I can continue working to track my calories and weight as carefully and exactly as possible.

I can continue working to keep the calories of my food intake as low as I can reasonably, healthily, and happily tolerate.

I can continue working toward keeping my weight as low as my body will healthfully allow.

I can work to ACCEPT the fact that things are just as they should be even though my body weight now has a BMI near the border between “normal” and “overweight”. Since my body appears to be unwilling to return to my original weight-loss goal … despite numerous, exhaustive attempts to force it do so, …. its continued refusal to cooperate with my weight-loss attempts might be an indicator that my body is already at its optimal weight for this late stage of my life.  

As part of my long-term Maintenance of a large weight-loss (currently 12+ years ), I do a lot of personal experimenting with various dieting issues. 

My experiment this summer from Memorial Day to Labor Day was to see how my own body’s weight results compared with the Body Weight Planner’s (BWP) projected calculations;

... while making a consistent and hard-core effort to drop my current weight lower in my Maintenance Weight Range (back below the 25 BMI border between “normal” and “overweight”).

The Overview pictured above shows my personal data input and the program’s projections for weight-loss. I’m age 72, going on 73, so I listed my age as 73.  I used the lowest percentage that the program will allow for my Physical Activity Level.

Based on my personal numbers, the program gave me an 1151 maintenance calorie burn. It projected that if I ate 900 calories per day for the 98 days between Memorial Day and Labor Day, I would lose from 133.2 pounds down to 126.0 pounds.  This would be a loss of 7.2 pounds over a 14 week period, averaging about ½ pound loss per week.

Note that the  program projects that at the end of the 98 days, in order to maintain a 126.0 pound weight, my calorie burn would be 1121, which is an ongoing 30 calorie reduction. 

This Simulation Graph shows that Increasing my calories from 900 for weight-loss to 1121 for maintenance would cause a weight UpBounce of 1.5 pounds over a 6 day period (98 days of dieting, + 6 days of maintenance = 104 days). 

Therefore my projected final ongoing weight result would be 127.5, which would bring me back just inside my “normal” BMI range.


Many years of keeping ongoing records of my weights and calorie counts have taught me that my personal metabolism burn is Lower than the Average rate predicted by Metabolic Formulas, so my personal diet plan for this experiment was to work to keep my daily calorie intake below 700 calories.

I chose to work toward a <700 calorie number because:

An 1150 calorie burn minus a food intake of 900 calories creates a 250 calorie deficit.

If my actual calorie burn was 900 instead of 1150, then a 250 calorie deficit would be 650 calories.
Also in my previous dieting experience, food intake of around 700 calories has been about the lowest calorie level that I’ve been able to sustain on diets lasting longer than 2 or 3 consecutive weeks.

I’ve had extensive experience with a great many different diets and ways-of-eating, and this has taught me that I tend to do best on a food plan that restricts the total daily AMOUNT of food that I eat (has a maximum daily calorie number), but does not restrict the KINDS of food eaten, nor restrict the FREQUENCY of eating.  Therefore, my food plan for this experiment allowed me to eat small amounts of whatever food I desired, whenever I choose to do so, as long as I stayed under my daily calorie maximum. 

My 5-bite dieting friends will understand when I say that 700 calories per day is the caloric equivalent of about 2 ½ Snickers or Protein bars. 

For an understanding of the kinds and amounts of food I normally ate during this experiment, look at the photos of meals I’ve recorded in RESOURCES, Photo Gallery section, under the heading Petite Meals.

I expect to soon post a discussion of the RESULTS of my Summer 2017 experiment in a separate article, entitled “Status Update - September 2017”.
