weight gain

[Guest guest]

I just had a question about weight gain. My son has been on the diet

for about 1 month, and his primary symptom is that he can not gain

weight no matter what or how much he eats. He is 5 feet 11 inches and

weighs 84 pounds. After starting this diet and reading I realized that

he might have mild Aspergers syndrome. He does not seem to be sensitive

to any of the foods on the diet. He has normal bowel movements. Can

anyone give me an idea of how long it takes to usually gain weight? Is

it usually a few months, I just wanted to know if the diet is working.

Thanks.
