Obesity 'may be largely genetic'

[DianaB]

My Mom and Dad were both small people, but my grandmother's were both heavy. Like Tink, I have hypothyroidism which effects my metabolism greatly. It's really hard to lose weight and to want to exercise. The thyroid problems come from my Mother's side of the family but didn't affect my Mother or my Grandmother, but I have two aunts that have it. Strange!
