I'm 10 days into one meal a day with no carbs, and I feel amazing. Today I feel like my mood was better than its been in months. Not hungry at all between meals, really enjoying what I'm eatin, which recently has been a 250g steak, a zucchini, an avocado and one other random veg, sometimes eggs sometimes not. One black coffee, one serve electrolyte drink, and lots of water
I absolutely do not believe you had no reason!
Edit: Oh constipation. Nope I am still regular - was a bit weird when I was doing only steak and eggs but now I'm adding veg it's perfectly normal for me
