I am pretty active, physically, and regardless, I am STILL substantially heavier than I was in my 20's, which has been more than two decades ago now. I don't know how to really fight the age issue when it comes to weight. It's easy to point at someone who is 20 and say "see, they aren't overweight". Whenever someone does that, I say "yeah....give them about 7-8 more years and check again". Even before I was out of my 20's the weight was coming on. Then after 30.....BOOM. Metabolism say "been nice knowing ya"
