Should You Let Your Body Determine the Intermittent Fasting Pattern by Hunger?

The top tip, which "is the most important tip," according to Dr. Berg, "you wanna let your body determine the intermittent fasting pattern by hunger. So here's the rule, don't eat unless you're hungry. This way will allow your body to transition to this at the right pace. Some people can fast longer than others. Once your body gets in this amazing adaptive state and you're burning fat, you should be feeling great mentally and physically. If you don't, it means that you're not ready yet and you have to keep doing it and just take your time."

RDN Says: "The body adapts to the schedule you give it. If you are used to skipping breakfast, it won't ask for breakfast. It won't signal that you are hungry until about the time you normally eat. You can actually fast for days (water only) and not feel very much hunger if you train your body by not feeding it. Yes, this will burn fat, but it will also start to waste away muscle and lower your metabolism, making keeping the weight off difficult and weight regain possible."
