90-30-50 method gains popularity as new nutritional trend

A new nutritional trend known as the ‘90-30-50 method’ is gaining popularity on social media platforms like TikTok and Instagram. Developed by American dietitian Courtney Kassis, the formula focuses on daily nutritional targets rather than banning specific foods.

The method prescribes consuming 90 grams of protein, 30 grams of fiber, and 50 grams of unsaturated fats per day. These figures are intended as nutritional floors rather than rigid ceilings. Proponents suggest that spreading these nutrients throughout the day—for example, aiming for 25 to 30 grams of protein per meal—can help preserve muscle mass.

Users of the program report potential benefits such as improved concentration, stabilized blood sugar levels, and more consistent energy throughout the day. The combination of high fiber to slow carbohydrate absorption and unsaturated fats for quality fuel is central to the approach.
