A freelance model shared her experience losing 4 kg in a week by following the 'Switch-On Diet,' a four-week program developed by Korean doctor Park Yong-Woo. The diet aims to activate the body's fat-burning mechanism by shifting energy sources from carbohydrates to stored fat, while preserving muscle mass and improving insulin sensitivity. It emphasizes protein and fiber-rich meals, strictly eliminates caffeine, alcohol, sugar, and processed foods, and incorporates gradual fasting.
