Green, not yellow
This is how the banana diet works.
Green bananas contain resistant starch, which keeps blood sugar levels low. This speeds up the fat burning process. This is why on a banana diet you eat green, unripe bananas instead of yellow and ripe ones.
And here's how the diet works:
Eat bananas for breakfast and as a snack between meals.
At breakfast, eat as many bananas as you like until you feel full. Make sure to drink lots of water to aid digestion.
Avoid high-fat foods for lunch.
Dinner is also entirely up to you. But remember: you should eat at least four hours before you go to bed.
As with any diet, you should exercise regularly and keep as active as possible. Clocking up 10,000 steps a day is ideal for most people.
And bananas are good for you in other ways, too: Although they are relatively high in sugar, they don't contain any fat or cholesterol. In fact, bananas are full of healthy nutrients: they are packed with vitamin B6, vitamin C, magnesium and potassium.
