Biological Adaptations that Promote Weight Regain
- POSTED ON: Mar 04, 2015

There is a “widespread misimpression” that weight-loss and maintenance for bodies which have become and stayed obese for more than a couple of years, is essentially the same as that for bodies which always have been:

  • normal weight (BMI between 18.5-24.9);
  • overweight (BMI between 25-29.9); or
  • have spent a brief time within Grade 1 obesity (BMI between 30-34.9).

In a commentary published February 26, 2015 in the journal Lancet Diabetes and Endocrinology, four weight-loss specialists set out to correct what they view as the widespread misimpression that people who have become and stayed obese for more than a couple of years can, by diet and exercise alone, return to a normal, healthy weight and stay that way.

"Once obesity is established, however, body weight seems to become biologically 'stamped in' and defended," wrote Mt. Sinai Hospital weight management expert Christopher N. Ochner and colleagues from the medical faculties of the University of Colorado, Northwestern University and the University of Pennsylvania.  

“Few individuals ever truly recover from obesity.” Those that do "still have 'obesity in remission,' and are biologically very different from individuals of the same age, sex and body weight who never had obesity." They are constantly at war with their bodies' efforts to return to their highest sustained weight.

That February 2015 commentary together with the August 2013 research article below explain many of the things that I have experienced personally, and that I have personally observed.

An additional article dealing with this issue is located HERE in the DietHobby Archives.

Time for a Reality Check
- POSTED ON: Jun 21, 2014


With regard to Dieting and Weight Issues, it is becoming clearly evident  that the members of the Medical Profession, including those who are part of the Scientific Community, are greatly in need of a REALITY CHECKA Reality Check is something which shows you that the real situation is different from what you believed or hoped. 

What is considered as "conventional wisdom" is that :

Most people burn X number of calories, and if they reduce that X number by 500 calories per day, in one week they will lose one fat pound (3500 calories = 1 fat pound). 

Therefore after doing this for 10 weeks, they will lose 10 pounds. Because they are now 10 pounds lighter, they will burn slightly less than the X number of calories their body needed before their weight-loss, and they can then easily eat that new X calorie number and maintain that weight loss.

This process can be continued indefinitely, and by following through, it will result in the body's loss of all "excess weight", and thereafter, will result in the body's maintenance of that "ideal weight" .  As a result of this people will become Thin and Healthy. 

At the bottom of this article, I give more detail about this numbers issue, but the POINT IS that while following this Basic Process gives short-term weight loss results, only a very few people ever achieve long-term weight loss results.  

Certainly, the REAL SITUATION Here is DIFFERENT from what the Medical Profession, the Scientific Community, and the General Public, BELIEVES or HOPES it to be.

DietHobby contains several articles about the dubious connection between being "Healthy" and being "Thin".  Also, some goo...
