I noticed two major physiological phase changes in my life. The first was when I was about 15 when I noticed puberty. My strength came on and in one year I went from benching 95lbs to 225lbs and gained 20lbs. The second was when I was about 46 when my body metabolism just came to a stand still. I'm pretty fanatical about my eating and I know that my body processed carbs in four hours and a steak in seven hours. At 46, my body processed carbs in 7 hours and a steak in over 12 hours. I could tell my metabolism slowed down by 50%. I had to change my eating regiment at that time. I had to eat the minimum amount to maintain my gains or I will gain fat. So for the last 10 years I've taken on the minimalism philosophy. Take the least amount of AAS to get gains and eat the minimal amount to maintain the gains. I'm just constantly fighting off the fat. The magic bullet against belly fat has been HGH. Taxman, you're young and you have leeway in eating because your body metabolism's still high. It may be a good to get into the habit of eating just what you need.
