A Korean diet plan called switch-on diet is trending everywhere as it claims to help burn fat in just four weeks. Obesity specialist Dr. Park, produced by Yong-Vu, includes intermittent fasting, protein-rich food in the routine, and its purpose is to support intestinal health and promote metabolism. It cuts sugar, processed foods, caffeine, alcohol and most dairy products. Carbohydrates are allowed, but only in small amounts. While the diet is designed to burn fat without losing muscles, some may find it very strict or very boring.

According to The New York Post, the plan first seven years ago Dr. Park appeared in the book, but has made a comeback online. An intestine health blogger wrote, “By the end of the week 1, I saw low swelling and better digestion. By the week 4, I had lost 4 and a half pounds of body fat and felt more energetically and mentally clear.”

The diet may look quick and effective, but it has not worked for everyone. A social media user said that he left the plan after five days. He lost some weight but tired of drinking protein all the time.

What to eat and how to eat in this Korean weight loss diet:

Week 1: intestine reset and detox

The first three days focus on giving a break to your digestion. You have four protein shakes a day, take probiotics in the morning, and go for one hour walk every day. If you feel hungry, you may have plain yogurt, tofu, or vegetables like cabbage and cucumber.

For the next four days, you add a low-carb, high-protein lunch to the plan. You can choose from chicken, tofu, fish, eggs, low -fat beef or boiled pork. You still need to avoid flour, coffee and most dairy products.
