Dietary modifications are clearly a required component for successful weight
loss. But, so is physical activity for most people. The National Weight
Control Registry ( http://www.uchsc.edu/nutrition/WyattJortberg/nwcr.htm )
has studied successful "losers" - their database contains information on the
habits of more than 3000 Americans who have, on average, lost 60 lbs and
kept it off 6 years.

Based on their studies, they have identified four behaviors common to
successful weight loss. Specifically:

1) They eat a low-calorie, low-fat diet

2) they monitor themselves by weighing in frequently

3) they are very physically active

4) and they eat breakfast.

See http://www.fda.gov/fdac/features/2002/102_fat.html

So, while exercise may not be required for weight loss, it is clearly an
important behavior to adopt if one wishes to be successful with weight loss
and maintenance over longer time frames.
