I'm a recreational weightlifter/bodybuilder and I agree that diet makes a huge difference. But, I am concerned about all the talk of cutting something out, like with keto. We should be talking about balance and increasing nutrients that are lacking instead. In my case, I got some rather severe digestive issues similar to IBS that turned out to be similar to what vegetarians get after several years if they don't watch their nutrients and vitamins. I spent 2 years battling it without knowing what was causing it. After days of conversations with some very smart friends, one of them suggested a connection between tryptophan and serotonin (which is made from it in the gut). Long story short, I started eating pork again (mainly bacon) after avoiding it for 20 years due to ethical concerns, and my digestive issues cleared up in a matter of days. My acne went away and my mood stabilized almost overnight. It was one of the most miraculous things I've experienced in many years. I also added psyllium husk fiber with meals 1-3 times a day and have maintained proper digestive function for several months now. Some things that really help me are zinc gluconate for immune function and recovery from exercise 1-7 times per week (too much will make you feel bad, a headache in my case), omega 3 capsules and glucosamine/chondroitin (which is for joint health but the mechanism likely happens through the gut as well). I also eat 2-4 whole eggs per day based on how hard I'm hitting the gym. My feeling is that the lack of fat in our diet from the 1980s till today has really wrecked most people's metabolisms and they are simultaneously frantically starving, fat from eating too much, and chronically malnourished.
