It all depends. I don’t have a will of steel, that’s for sure. I started it to lose weight but have continued after my chronic heartburn stopped immediately, my eczema went away, my blood sugar came down and my triglycerides dropped to a normal range. I take 0 prescription meds now.
I feel so much better, no longer have heartburn wake me up in the middle of the night, and no longer have my fingers crack and bleed from eczema. 7 years in and it’s really no trouble staying on the diet. The 45 lbs I lost turned out to be a minor benefit of the diet, not the major benefit.
