Metabolism Is Modifiable With The Right Lifestyle Changes

Some important stuff, here.
"The human body can be trained to burn more daily calories with the right nutrition and exercise modifications, according to an expert at American College of Sports Medicine's (ACSM) Health & Fitness Summit & Exposition.

Liz Applegate, Ph.D., FACSM, director of sports nutrition at the University of California at Davis, says resting metabolic rate - the amount of calories the body burns in a resting state to keep internal organs operating - can be improved through lifestyle changes. The easiest way, she says, to calculate metabolic rate is to figure 10 calories burned for every pound of body weight for women, and 11 calories for every pound of body weight for men. For instance, a 130-pound woman has an approximate resting metabolic rate of 1,300 calories per day."
Note that the RMR (resting metabolic rate) calculation ACSM uses.

This is an important number since the RMR is about 2/3 of a person's daily caloric needs, on average.

Most overweight/obese persons are not 130-pounders. At, for example, 200 pounds, a woman's RMR is 2000 Calories, a man's 2200. This places their maintenance Calories, i.e., the Calories needed for a stable weight, at 3000 for the woman and 3300 for the man.

From ACSM's own starting point, it is easy to understand:
If you do read the rest of this ACSM press release, also note that it states that you can "replace...fat with muscle," which is impossible and that muscle gain can apparently be accomplished in a weight loss setting, also impossible since you have to gain weight to gain muscle, i.e., you are adding weight to your body as lean tissue.

More proof, IMHO, as to just how low the bar is set to be an "expert" in the fitness domain.

BTW, isn't metabolism also modifiable with the wrong lifestyle changes?

"Wrong lifestyle changes" as in the ones experts, like the ACSM, recommend.
