Personal experience says otherwise. Low carb/slow carb diet plus fasting 100% did it for me. 40 lbs gone, and have kept it off even while backing off of the initial rigidity. Everything in moderation, especially alcohol. Beer is a huge carb load, so that had to go entirely. Pasta as well. Potatoes too. Sure, I have a couple fries (or chippies for the BBC crew), but it’s all about those being scarce. It’s actually pretty easy to intermittent fast. Eat dinner and be done before 8pm and have lunch around 1pm the next day. Have coffee or tea in the morning.

What really accelerated weight loss for me was extremely rigid ketogenesis. Felt amazingly sharp and dialed in every morning, slept well, shredded pounds.
