Wow. I was never that lean, genetically I'm build to carry more fat, think lowest I ever got was mid teens %.I was in great shape up until age 59. Between 59 and 60, I aged 10 years. During that year, prostate issues, angry kidneys, diagnosed with diabetes and on meds and now both shoulders.
I was always a skinny kid and was 6' and 126lbs in high school. I discovered bodybuilding my senior year in high school and met a muscle head in the gym. He asked me about my diet and exercise program and I proudly told him about my chicken breasts,and vegetables and my unstructured lifting routine. He said "nope" and told me to eat 10 ham sandwiches and day, with as much cheese and mayo that they would hold. He also told me to chain myself to the squat rack, bench and barbell rows.
That year I gained 50lbs and most was muscle. I became very interested in nutrition after that and changed to an almost perfect diet pretty much since then. At my prime, I walked around at 216lbs and 8% body fat.
At age 57, I took a year to see how good of shape I could get in. I achieved 6% body fat at 185lbs.
At 59, I started losing a lot of muscle mass and now I have trouble maintaining weight. The very low carbs and diabetes medication is a lot to blame. I am at 165lbs now and I bet I could fit both arms in 1 sleeve of that blue shirt in the picture.
My thinnest at 6'5 was in high school where I was 197lbs. Basically skin and bones. Then college I basically ate a ton of pasta and chicken parts combined with weight lifting trifecta.
Hope your health improves.!! Touch wood other then a torn right shoulder labrum causing looseness/instability, I'm still feeling pretty good in the weight room.
Will fight the aging, kicking and screaming every step of the way if I'm able to lol
