Eat and lose weight: this product will help you lose weight – verified by Katy Perry

When the singer needed to get in shape, she tried the mushroom diet. Who invented it is unknown, but its essence is quite simple – no tedious calorie counting or intermittent fasting. Only one meal a day should be replaced with a serving of mushrooms.

Replacing them with meat or pasta can cut calories and add nutrients like zinc. Mushrooms may even be good for the brain – some research suggests that eating mushrooms can help keep your mind sharp later in life.
