Hello, cucumber and banana are both fruits with high nutrition and low energy. Only these cucumbers and bananas can be eaten every night, but breakfast and lunch should be eaten as usual, so long-term persistence will be effective. In addition, it is best to cooperate with aerobic exercise, such as skipping rope, cycling, playing badminton and hula hoop for about 30 minutes every day, which also needs long-term persistence. I hope my answer is helpful to you!
