Well I have tried them all I think. Cutting calories never worked for me. I was vegan for almost 3 years which was actually a pretty easy lifestyle for me, but I developed pretty significant anemia and craved red meat. I do credit a plant based diet with reversing my diabetes. I was full carnivore for a couple of years which was also pretty easy because it eliminates cravings if you are strict about it. My blood sugar has been stable for years now so I eat very low carb and smaller portions. My husband gets way too skinny on low carb so I just add things like potatoes, homemade protein ice creams to his diet. We both eat pizza he makes at home 1-2x/month with no issues.
