One thing that isn’t talked about enough with IF is that it’s very easy to pick up an eating disorder. Once you learn how to be hungry, it’s very easy to say “I can wait another 30 mins” and do that 5 times and then it’s been 24 hours since you’ve eaten. Or to get obsessive about waiting so you lose just a little bit more. When it’s time to eat, you need to eat. If you already have a bad relationship with food, this isn’t going to make it better. Just be aware that it’s not foolproof.
