Dietary Calorie Restriction

Calorie restriction, i.e. "counting calories", is one of the most effective ways to control your weight. It allows individuals to eat what they desire, but in limited amounts. For more information, visit: http://en.wikipedia.org/wiki/Calorie_restriction

There are only two ways to lose weight. You've mentioned one; calorie restriction. The other way is to increase your metabolism. This means regular exercise, enough to raise your baseline metabolism to a point where your body burns more than you are taking in.

A restriction map plots restriction sites within a chain of DNA. You cannot create a restriction map without restriction enzymes. Restriction sites are points in a DNA molecule that contain certain strings of nucleotides, which can only be identified by restriction enzymes.
