You are so lucky to have taken such a health-wise decision. Yet, I think you need to proceed gradually to allow your body time to re-adapt to the diet change. Depending on your diet (carnivore, vegetarian, Keto or LCHF) you need to be alert on your electrolyte balance, sufficient amount of vitamins, protein, dietary fiber, and fats. We have all gone through a process of trial and error, so you'll need to experiment with your menus to see what works well for you; our bodies react differently to macro-nutrients. Good luck.
