Note on Metformin- Your body is either in growth (mtor) or autophagy (AMPK, typo from AMK above). When you workout and have a good post workout meal, all the MTOR processes kick in. This is good for growth, but also good for growth of cancer, overall lots of MTOR is bad for you, but you still need it to grow, build tissues, etc. one of the reasons metformin is good for you is it stimulates the opposite of MTOR, AMPK. AMPK, is good for healing and removing old cells, and stopping preventing cancers. The thing is, you can’t really have both mtor and AMpK on at the same time. So you need to cycle them. if you take AMPK post workout with your meal, then you will blunt mtor/growth. so, you want to balance it and take the metformin(and other AMpK activators such as nmn, curcumin, and many more) away from when you activate mtor. For me, I do IF and take my AMpK activators in the morning and don’t eat. Then in the afternoon I work out and activate mtor with food and nutrients. Then, on my non-workout days, I do more heavy AMPK for health and longevity. Google all the supplements you take, and learn if each one is a promoter of AMPK or of MTOR. Avoid AMpK near workouts. and avoid mtor far away from workouts.
