I am very interested in fasting and I tried time-restricted eating first (18:6). I heard a lot of health benefits of fasting and ketosis but I have some questions.
If I fast for 18 hours and then eat carbs, doesn’t that mean that I am out of ketosis? Does time-restricted eating has any benefits if not on a low carb diet?
Thanks for the answers.
I suppose depends on what you are looking for. If you fast got 18 hours then eat junk food for 6 then there will be few benefits. If you instead eat lots of complex carbs such as beans, vegetables, whole grains then you’ll have loads of benefits.
IF can still be beneficial on a non-keto diet. I personally think fasting while not keto is difficult due to carb cravings but some people do it
Essentially you’re restricting caloric intake with the fasting (unless you’re bringing during your eating window) and that’s why it still works.
I think It’s beneficial as your body produces less Ghrelin. All those calories saved from the ‘skipped’ meals add up to enormous health benefits over a period of time, without any hunger once your body has adapted to not eating at certain times.
Calories and food quality will make a difference but its still probably better to eat one or two carby meals a day than three
Yes, ketosis rises as insulin drops. You get some in an 18 hour fast and that’s better than none. If you want the real gold, you gotta hit 36-48 though. It is easier with a healthy diet, if not low carb, but neither are essential.
IF, when done correctly, is calorie restriction. You can overcomplicate it by getting hung up on keto and autophagy (which occurs during a 36+ hr fast anyway). Eat the carbs. Watch the processed sugars. It’s the processed sugars that make fasting that much more insurmountable in my personal experience. I once had a registered dietician look me dead in the face and explain that ketosis is the unhealthiest thing one could do to one’s body, based on how acidic the body becomes in that state. There are documented examples of ketosis working for individuals with neurological disorders, but if that isn’t you, I would avoid it.
