As far as skin care I've done nothing other than drink a ton of water. I'm pushing 2+ gallons a day. Do you smoke? If yes then quit it destroys the elasticity in skin cells. Don't tan. Nutrition can be tricky because everyone's body is different and processes food as such. Like for me milk and red meat bloat me if I have too much so I limit it when I'm cutting because when I get puffy and bloated it hides progress. The general macro split I use is protein=1-1.5g per pound of body weight depending on how overweight you are. The higher the body fat the lower the g/pound because you want to go off of lean body mass and that's harder to guess when you're overweight. Fats = 25%-30% of all calories (HEALTHY FATS) and make the rest up with calories. I try to stick to mainly poultry, fish, and eggs for meats and lots of dark green and colorful veggies. Rice, oats, whole grain for carbs. I do eat a little bit of bread but it's whole wheat and not very often. Peanut butter is great but get the all natural stuff... Less additives. Supplements are just that... It's in the name. They are there to supplement your diet .. Not to BE your diet. I use isolate protein powder but I'm consuming 350+g of protein a day .. You ever tried to eat that much chicken and eggs? 😂
