When we hear the word “malnutrition,” many people still imagine famine-stricken regions where food is scarce. But in the modern world, a new kind of malnutrition is dominating: overnutrition combined with nutrient deficiency.

The World Health Organization (WHO) reports that obesity rates have tripled since 1975, yet simultaneously, billions suffer from deficiencies in iron, vitamin D, magnesium, and essential fatty acids. This paradox is sometimes called “hidden hunger.” People eat plenty of calories — often too many — but their bodies are starved for quality nutrients.

Why does this happen?
Because modern diets are built around hyper-palatable foods — engineered combinations of sugar, fat, and salt that hijack the brain’s reward system. These foods provide quick energy but very little nourishment. You feel full, yet your body still craves something essential.

Here’s where intermittent fasting, combined with mindful eating, can help. By restricting the eating window, you naturally reduce the frequency of mindless snacking. Instead of grazing all day on processed foods, you give your body periods of rest and recovery. Apps like Fastry enhance this by giving you structure and accountability.

And when you do eat, you can focus on nutrient density — lean proteins, colorful vegetables, healthy fats, and whole grains. It’s not about eating less food; it’s about eating better food, at the right time.

Hidden hunger is real, but it doesn’t have to define your lifestyle. Fasting gives your body the pause it needs to reset its signals and reconnect with true hunger.
