Low calories and work capacity

Low calories and work capacity

1. Really low calorie diets intensify activity of fat-storing enzymes and decrease the activity of fat burning enzymes. The chief fat storing enzyme is called Lipoprotein Lipase (LPL). When you dropyour calories too low, your body will produce more LPL and less fat burning enzymes. Inother words, when you don’t eat enough, your body changes its chemistry to make iteasier to store fat in the future.

2.. Really low calorie diets put down output of thyroid hormone. The Thyroid gland is largely responsible for the regulation of your basal metabolic rate (the rate at which you burn calories at rest). When your body senses a severe reduction in calories, there is a corresponding reduction in the output of active thyroid hormone (T3). The result is a decrease in your metabolic rate and fewer calories burned.

3. Really Low calorie dieting is attracting the rebound weight gain. Almost everyone loses weight initially on a very low calorie diet, but it nevertakes long before the body catches on and starts conserving energy. That’s when you hit aplateau. Once you hit the plateau, it becomes much harder to keep losing weight even ifyour calories are extremely low.This lack of continued results, combined with gnawing hunger pangs and insatiable craving, usually causes people to give up out of sheer frustration. They go off their diet, the weight creeps back on and their body fat ends up back where they started – only now they have less muscle and a slower metabolism. With a slower metabolism, what used to be a maintenance level now becomes a surplus, and the weight comes right back on. Most people gain back all the weight they lost– and some gain back even more, leaving them fatter than when they started. This up and down pattern of weight loss and weight re-gain is commonly known as the “yo-yo cycle”, and it often continues for years or even for an entire lifetime. With each repeated bout of dieting, your metabolism becomes less and less efficient and you can actually become progressively fatter while eating less food.

4. Really low calorie diets make your appetite and cravings bigger. When your body goes into starvation mode, this triggers increased appetite andcravings in an attempt to get you to eat more food. The hunger and cravings can be sostrong that you become ravenous. It’s virtually impossible stay on a diet when you arevoraciously hungry and all you can think about is food. Few people have that strongpower of will.

5. Really low calorie diets take away your energy and work capacity. Low calorie diets leave you tired, lethargic and unable to sustain high levels ofactivity or intense workouts. Dr. Lawrence Lamb, author of “The Weighting Game: Thetruth about weight control” points out that “The first sign of under nutrition is the loss ofenergy and the inability to sustain prolonged physical work. There is a direct relationshipbetween calories consumed and the physical work a person can do.”If you have no energy to work out, you’re going to feel lousy and seriouslycompromise your results. The ability to train hard aerobically and with weights is a must-thing if you want any real, long term results.
