Not too long ago, dietary advice was “one-size-fits-all.” Everyone was told to follow the food pyramid, count calories, and avoid fats. But science has moved far beyond that. Today, we know that nutrition is deeply individual — what works for one person might fail for another.

Here’s where artificial intelligence (AI) is revolutionizing the field. By analyzing massive amounts of data — genetics, microbiome profiles, lifestyle habits, wearable sensors, and even sleep patterns — AI can predict how your body will respond to different foods.

A groundbreaking study from Cell (2015) showed that even identical foods can produce dramatically different blood sugar responses depending on the individual. Two people could eat the same slice of bread, and one might experience a sharp glucose spike while the other has almost no reaction. That means the “best diet” isn’t universal — it’s personalized.

AI-powered nutrition apps are now learning from this data and offering tailored recommendations. Imagine logging your meals, and instead of generic advice like “eat fewer carbs,” the app says: “On days when you eat pasta at night, your sleep quality drops. Try moving that meal earlier in the day.” That’s the power of pattern recognition.

Fastry’s philosophy of intermittent fasting fits right into this future. While AI works to personalize food choices, fasting offers a universal framework: giving the body rest periods where no digestion occurs. Combining AI-driven personalization with fasting windows could be the next frontier — nutrition that adapts not only to who you are, but also when your body needs a break.
