I cut out all gluten/wheat and peanut butter. I’ve lost weight and maintained strength, maybe even gained some depending on how you look at it. Cutting the gluten and peanut butter has made me feel better over all, especially when it comes to feeling bloated.
Find a good protein shake. Not one that tastes good, but one that you feel ok after drinking and has a lot of protein in it. Right now I’m using a vegan mix. It’s disgusting, but it’s healthy and doesn’t make me feel like crap when I drink it.
Another thing I do is have a little reward. A handful of gummy bears satisfies my sweet tooth and is something to look forward to after a workout.
Listen to guys like 03RN and Robert Mitchum. Also don’t be afraid to put on some weight if doing so makes you feel better and makes you healthier.
