No it's not good for you.
Trust me I thought could but no wasn't. So just have small meals and eat healthy snacks.
Example
Carrots cucumber celery cheese fruit you like. Hard boiled eggs are also good.🤗

I intermittent fast. It helps my weight loss and cholesterol. My Dr. Loves it.

I think it's best to clear it with your doctor.
I think it depends on a few factors :
How long the fast
What meds you're taking
How you feel when you fast etc.
I think it's important to eat though to keep your immune system strong, esp. healthy foods and clean foods.
Still, every person is different, so I think clearing it with your doctor is the thing to do.
