Morning Banana Diet books published since March have sold more 730,000 copies. A singer appeared on TV saying she'd lost 15 pounds in six weeks on the diet, and the next day, there was a banana shortage across stores in Japan, according to Time.
Here's how the morning banana diet works:
1. Eat a banana and glass of water for breakfast
2. Eat anything you like for lunch or dinner, as long as it's before 8 p.m.
3. A three o'clock snack is recommended
4. No desserts after meals
5. Go to bed before midnight
The banana diet was designed by a Japanese pharmacist named Sumiko Watanabe. She claims the secret to her diet is increased metabolism. Her husband was overweight so Watanabe came up with a diet plan for him. Watanabe subsequently lost 37 pounds.
