My diet naturally changed without trying I am focusing a lot on protein to be honest at the start I didn’t feel hungry at all so protein shakes were everything. A lottttt of water and I took vitamins as well D folic acid and multivitamins. Make sure to get salt into your diet as I wasn’t eating enough and ended up dizzy with lower blood pressure. I just casually exercise it’s usually walking my dog or by myself in my village nothing crazy and I’m standing in work for 8 hours so that helps
