I have been following IF on-and-off over the past few years. It has helped me lose weight initially and then maintain it at a good spot. I have not done detailed before and after blood work to know whether it has had other effects. But one problem I have started having recently is acid reflux and acidity. People immediately pounce on this and tell me that skipping breakfast is what is causing increased acidity levels in my stomach. And my doctor is also suggesting that I do not skip breakfast. The problem is I do not have any concrete evidence for either case (skipping breakfast causes/does not cause acidity). I am hoping to get my acidity issues under control first and then maybe give IF another shot to see whether the acidity issues return. Just wanted to throw out there that different people might have different experiences with IF and it is very important to listen to your body.
