According to Sherrie, the Switch-On Diet is a four-week programme developed by a Korean doctor and is designed to activate the body’s fat-burning mechanism. According to a New York Times report, the Korean health regimen was created by obesity researcher Dr Park Yong-Woo.
The core idea behind the plan is to promote fat loss while preserving muscle mass and improving insulin sensitivity. Sherrie explained that the diet helps the body shift from using carbohydrates to burning stored fat as its primary source of energy.
She also pointed out that everyday eating habits can slow weight loss. Diets high in sugar, refined carbohydrates, and unhealthy fats may be calorie-heavy but low in nutrition, making fat loss harder. The Switch-On Diet tackles this by cutting out these foods and focusing on protein- and fibre-rich meals.
Protein plays a central role in the plan, helping prevent muscle loss during weight reduction. The diet strictly eliminates caffeine, alcohol, sugar, processed meats, and highly processed foods. Fasting is another key element and is introduced gradually over the weeks.
How is the four-week Switch-On Diet structured
Explaining the structure, Sherrie shared that the first week focuses on detox and gut reset. For the first three days, all meals consist of protein shakes, after which vegetables and high-protein foods are gradually added to support digestion and reduce bloating.
The second week introduces intermittent fasting alongside high-protein meals to support muscle recovery while staying in a calorie deficit. By the third week, fasting days increase, and the focus shifts more strongly to fat burning.
As the programme progresses, the food list expands to include items such as multigrain rice, lean chicken, fish, eggs, nuts, berries, bananas, and sweet potatoes. However, sugar, alcohol, and processed foods remain restricted.
Reflecting on her experience, Sherrie said the diet helps burn fat while protecting muscle mass. She also revealed she had followed the plan before and saw a noticeable reduction in body fat. However, winter-related lifestyle changes affected her gut health and hormones, leading her to reset with a short fast before restarting the diet. This time, she also cut out dairy, increased fibre intake, and focused on anti-inflammatory foods.
