Ralph DuBose writes:

The real difference between "naturally" thin people and the
easy-to-be-fat variety is in the difference in the amount of
spontaneous, unconscious activity that is carried out. Fat people just
sit there. Thin people squirm, fidget, climb around in their chair.

The real difference is that thin people eat less food than fat people.

Fat people claim that thin people "eat all they want" and never gain
weight. Well, thin people don't want to eat very much. If you actually
observe what thin people eat during the course of a single day, and what
fat people eat during the course of a day, it's very easy to see why the
thin people stay thin, and the fat people stay fat.

Exercise per se may not burn huge amounts of calories but it
increases muscle tone and makes it more likely that a person will be
more mobile and active in every area of life.

Exercise is always a good thing. However, one should not assume (as fat
people often do) that increasing exercise makes eating restrictions
unnecessary. To lose weight, you really _must_ eat less; most fat
people cannot afford to exercise enough to burn off all the calories
they consume by overeating, and often they are in such poor shape that
exercising to that extreme might be dangerous. So cutting calories is
necessary whether you exercise or not, and fat people who think that
they can just exercise a bit more and become thin, while still eating
double portions at every meal, are dreaming.
