In normal healthy individuals, what negative effects does fasting have?

[Anonymous]

I've read many positive things regarding fasting. Is there any research that shows fasting speeds up any degeneration of body?

No, in fact the opposite is true.

The most prominent negative affect is that you are grumpy and can't participate in breakfasts and brunch. :p

There can be losses in muscle mass. Doing resistance exercises can attenuate muscle loss.
I sometimes have a no carb breakfast of an egg with extra egg whites to boost my protein intake with minimal insulin release as an alternative to a longer fast.

I’ve done 16/8 IF for a year and have lost 30 lbs while gaining muscle.

It made my IBS worse

Low blood sugar, fatigue, lightheadedness in some people.

I found IF to be easy and effective, but it did give me acid reflux, which I'd never had an issue with before, so I had to stop.

Almost all the research has been done on men so I would tread carefully if you are a woman.

Far more benefits than negative effects in normal healthy individuals. Some folks with certain health issues need not apply.

YES! BREAKFAST and brunch rock. I misssssss them on IF. And sometimes I do eat them, but I feel best if I don't.

With minimal daily exercise the muscle loss does not occur. Check out huberman podcast on fasting

It also made my IBS so much worse. And I didn't lose a single pound. I'm so jealous of those who have had success with it, because other than the IBS issues, I found it quite easy to do.

Fasting destroyed my metabolic system and I have to take prescription supplements now. I guess I fall under the not-nornal healthy individual, but I didn't know it until after I had a metabolic crisis.
