Make sure you NEVER Crash Diet

RULE #1
NEVER CRASH DIET
Never again reduce your calories to the point of hunger and weakness. Whenever you do, your body might lose fat, but only temporarily. Such dieting increases the production and the biological activity of a fat-storage enzyme called lipoprotein lipase. When you go off the diet, this enzyme continues to be overactive. It collects fat and deposits it again with such efficiency that your bodyfat is soon slightly higher than it was before you began. Thus, as a direct result of dieting, you have increased your bodyfat.
