I keep it simple. I do a kettlebell routine 3x a week. I'm pressed for time as it is, so I can get an entire routine done in about 35 minutes or so. I purposely do it in the mornings before my day really gets going. If you have some interest, I can point in the direction of setting up your own routine. No need for a heavy bell, I stick with a 35 pounder myself. Best part is you can pick an Amazon bell for rather cheap.
As far as diet is concerned, I tend to eat very clean. I don't do added hormones/antibiotics. I eat a lot of whole vegetables and the like. No need to overthink a diet. If you cut out the sugar and the refined/processed garbage, you'll see a difference, immediately.
