Answered by Dr Itender Pal Singh
Intermittent fasting comes up in almost every diet conversation I have with patients these days. My honest answer: it’s safe for many healthy adults, but it’s not for everyone.
For most healthy people, restricting eating to a window of time — like 8 hours a day — appears safe and may help with weight management and blood sugar control.
Who should avoid or be cautious with intermittent fasting:
- People with a history of disordered eating
- Pregnant or breastfeeding women
- People with diabetes, especially those on insulin or blood sugar medications
- Anyone with a history of low blood pressure or fainting
My advice: If you’re generally healthy and curious about intermittent fasting, it’s reasonable to try, ideally starting gradually. But if you fall into any of the higher-risk groups above, talk to your doctor before starting — the risks can outweigh the benefits for you specifically.
