With all the diet books out there why are so many Americans are still overweight and in poor health?
The answer is simple, "You don't need a diet book actually you need to change your lifestyle". Please read this week's tip and include it into your fatloss program.
Tip of the Week!
If you walk a mile you will use less energy than someone else who walks the same distance, but weighs more. If you do it quicker your energy usage will differ from someone doing it slowly.
Dr Willett's study mentioned above talked about how, when people changed to a low-fat diet in a metabolic ward experiment for a couple of weeks they lost some weight. However, a few weeks later, when the subjects had returned home, the regulatory systems in their bodies ensured that the weight they lost was replaced. Therefore, it doesn't work. The problem with this approach is that you cannot know how much energy to take in. Neither can you know how much you are using.
The second Golden Rule of orthodoxy is: A calorie is a calorie is a calorie' no matter where it comes from. This rule says that nomatter what you eat, if you eat more calories than you use, you willgain weight.
The figure often used is that one kilogram of body fat represents about 3500 calories. But according to the United States Department of Health, Education and Welfare:4 On a high-fat diet, 4703 to 8471 excess calories were required for each kilogram of added weight.
However, a study of a low fat VLCD very low calorie diet, replacing fat calories with 8g/day of equivalent carbohydrate calories reduced weight loss by 1.68kg. This corresponds to 3300 calories of carbohydrate/kilogram, possibly 2500 calories per kilogram for carbohydrate alone.'
Hey, wait a minute, read that again! What they are saying is that it takes 4,700 to 8,470 excess calories from fat to add akilogram of weight, yet it takes only 2,500 to 3,300 calories from carbohydrate to add the same amount. So a calorie is a calorie is a calorie' is not so meaningful after all: a carbohydrate calorie is obviously much more fattening than a fat calorie. So do calories count? Of course they do but some don't count half as much as others.
There is an emerging scientific consensus that the old ideas, that overweight people are lazy gluttons, are now realized to be as absurd and insulting as the overweight have always thought they were.
