Totally agree, up to a point.

You're right as far as football is concerned, if someone were to come in and say, "you're not allowed to weigh that much," then they would be laughed off the field.

The key difference between weight loss and weight gain is body deprivation.

As far as disadvantages, I don't get it. It doesn't say you have to lose 1.5% a week. Is that what you meant or am I reading wrong?
