Not so sure I totally agree with you there Sue. Problem for most people is
that the body adapts to lower caloric intake by reducing metabolic rate.
Certainly both caloric reduction and aerobic exercise will eventually work,
but it has to be a lifestyle change rather than a temporary diet. Most
people lose excess water weight at the beginning also. The body likes to
keep its fat reserves.
