Ten years ago, if you told someone you were “fasting,” they might have assumed it was for religious reasons or as a form of detox. Today, intermittent fasting (IF) has become one of the most studied and practiced nutritional strategies worldwide. But unlike many diet fads that quickly rise and fall, IF is proving to be far more than a trend.

So what makes it scientifically powerful?
Researchers have shown that fasting does more than simply reduce calorie intake. A landmark review published in The New England Journal of Medicine (2019) explained that intermittent fasting can:

• Improve metabolic flexibility – your body becomes more efficient at switching between burning glucose and fat.
• Enhance insulin sensitivity – lowering the risk of type 2 diabetes.
• Stimulate autophagy – the body’s cellular “recycling system,” where old and damaged cells are broken down and replaced.
• Reduce inflammation and oxidative stress – two major drivers of chronic diseases.

Even more interesting, fasting aligns with our evolutionary biology. Our ancestors didn’t eat six small meals a day — food availability fluctuated, and the body adapted to thrive during fasting periods.

This is where Fastry makes a difference. The app doesn’t just tell you what to eat — it guides you on when to eat. Instead of obsessing over tracking every calorie, you simply follow a structured eating window. It’s easier for your brain to stick to “no food after 8 PM” than to calculate whether your snack was 257 or 312 calories. That’s why many users describe it as liberating rather than restrictive.

Intermittent fasting isn’t a miracle cure — but paired with balanced nutrition, it’s one of the few approaches that consistently holds up under scientific scrutiny.
