I used to interview elite bodybuilders on their training and eating for a
 living and did this for years and years. One reoccurring theme that 
kept popping up when talk turned to diet/nutrition was how much food top
 bodybuilders packed away on a daily basis. These men taught their 
bodies how to handle continually greater amounts of calories without 
becoming fat. Contrast this with the typical obese person who eats one 
meal a day and adds body fat at the drop of a hat. I am working with a 
crew of obese folks and having great success using modified bodybuilder 
eating tactics to help the obese lose body fat.
The first order of business for the obese is to establish a multiple 
meal schedule. The obvious advantage to this strategy is it divides the 
daily calories in smaller chunks. I require the obese person to eat 
every three hours and this usually works out to five feedings a day. 
Secondly we insist they clean up the food selections. Some foods are 
easily converted into body fat (sugar foods, manmade foods and saturated
 fat) and some foods are near impossible for the body to convert into 
fat (lean protein, fibrous carbohydrates). The body's metabolism kicks 
into high gear to digest protein and fiber - creates what is called the 
thermogenic effect of food. Body temperature actually increases when the
 digestive system is faced with the daunting task of breaking down hard 
to digest protein and fiber.
Multiple meals allow the body to deal with fewer calories at any one 
sitting and the repeated practice of eating 5-6 meals a day teaches the 
body to become adept at digesting and distributing food. Better to eat 
3,000 "clean" calories a day divided into six five hundred-calorie daily
 meals than one 1,500 calorie mega-dirty fast-food meal.
The results are astounding when the obese buy into the approach. I have 
one male who has lost 40-pounds of bodyweight in 40 days while 
simultaneously adding 12-pounds of muscle. He started at 240 and 
yesterday he weighed 200. This is far more impressive because didn't 
lose muscle in the process, he added muscle in the process. This was no 
ex-jock loaded with muscle memory; this is a 48-year old man with zero 
weight training experience.
Obese folks who slash calories end up losing as much fat as muscle and 
end up as miniaturized versions of the old fat selves. This modified 
bodybuilder approach melts fat while simultaneously adding muscle: the 
obese person eats more and as a direct result feels energized and 
vibrant during the process. Contrast this with the calorie-slasher who 
feels deprived, denied and continually on the verge of a binge. A person
 who eats wholesome foods every three hours is far less likely to binge 
and blow their diet than some poor obese person subsisting on 1200 
calories a day. The calorie starved obese individual has set their 
caloric ceiling set so low that eating a candy bar or a bowl of ice 
cream causes them to add five pounds in 24-hours.
Adding functional muscle and building strength allows the obese person 
to become mobile and adept at climbing steps, getting out of a low chair
 and powering their bulk around. Compare this to the calorie-slasher who
 actually weakens their already weak body. Those who depend on 
deprivation to trigger bodyweight loss weaken the immune system and 
continually contract colds and sickness.
Those who live on 1000 to 1500 calories a day live in a stressful 
psychological world of denial. A person who has elevated their 
metabolism and consumes 3,000 calories a day can absorb an occasional 
binge far, far better than a person starving; I allow my folks a cheat 
meal once a week: this allows them to feel psychologically free. The 
interesting thing about the cheat meal (not cheat day - cheat meal) is 
that by "being good" the other 6 7/8's of the time the sweets, fat and 
junk they crave and might eat are rejected by the body and classically 
results in diarrhea
