Viral Korean diet promises to burn fat but maintain muscle in 4 weeks

If you’re struggling to lose weight, you may need to switch gears.

A Korean doctor has devised a four-week metabolic reset program that’s gone viral based on claims it causes rapid weight loss. The Switch-On Diet focuses on intermittent fasting, protein-heavy meals and gut optimization to promote fat burning while preserving muscle mass.

“By the end of Week 1, I noticed less bloating and better digestion,” a gut health blogger recently shared. “By Week 4, I was down [4.5 pounds] of body fat, felt more energized and experienced surprising mental clarity.”
