I do at least two 36 hour fasts a week. I was surprised after about 6 months that I no longer had anxiety issues. I even was able to stop my anxiety meds and never needed them again. I lost a ton of weight, but the other benefits far outweigh the weight loss.
I also wanna take the plunge again because I gained some weight during these past two years when I was already trying to lose some, and I remember that the times I’ve managed to be consistent with 16:8, 18:6, 20:4 or OMAD I felt amazing. I have a chronic illness and fasting was recommended by my doctors, so I still fast for 12 hours or so. I managed to keep my symptoms in check and my mental health improved radically. My headaches lessened, I barely have stomach issues and I never get sick. I haven’t even had covid yet, so overall health improvements are also part of the package. There are positive studies about IF, autophagy and cancer out there too :) I wish you luck with your journey!
Btw, can I ask how are you tracking your calories? They always drive me nuts.
