Is fasting really the secret to weight loss or just another diet trend? Should you try intermittent fasting or go for longer fasts like water-only fasting? And most importantly, what are the real benefits and risks?
These are the questions that health expert Prashant Desai from Stanford School of Medicine explored in a recent podcast, where he shared both science and personal experience.
Fasting, in simple words, means “to go without.” While we mostly associate it with food, it can apply to many areas of life (like social media, shopping or even speaking). Religious fasting is often about discipline and spiritual growth. On the other hand, Health fasting is about supporting the body through intentional eating patterns.
Intermittent Fasting Vs Long Fasting For Weight Loss
Intermittent fasting (IF) is one of the most popular methods today. It involves eating during a fixed window, such as 16:8 (16 hours fasting, 8 hours eating) or 18:6. It is easier to practise daily and fits into most lifestyles.
Long fasting (also known as extended fasting) usually goes beyond 24 hours and can last for 36, 48, or even 72 hours. This is more intense and not sustainable for everyone. Desai noted that both methods have benefits, but intermittent fasting tends to be safer and easier to follow for most people.
Benefits Of Fasting
According to Desai, short-term benefits include:
1. Weight loss and fat reduction
2. Better insulin sensitivity
3. Improved metabolism
4. More energy and mental clarity
Long-term benefits may include reduced inflammation, improved cellular repair (autophagy), and possibly a longer lifespan. However, more human studies are needed to confirm these effects.
Who Should Avoid Fasting
Fasting is not for everyone. People with diabetes, eating disorders, pregnancy or certain medical conditions should avoid it unless advised by a doctor. Desai also reminded listeners that fasting is not magic. For weight loss, the principle remains the same. You need to eat fewer calories than you burn.
Desai concluded, “In the end, fasting is a tool. If done correctly, it can help you not just physically but also mentally and spiritually.”
Whether you choose intermittent fasting or try longer fasts for weight loss or any other goal, the key is to listen to your body and follow what feels sustainable for you.
