Lose weight, be sure to stick to it! If you persist in this way, you will definitely lose weight. As for whether you can lose 20 pounds, it's hard to say! If you are not very fat, don't lose weight. Health is the most important! I am also losing weight, but as long as I don't eat a meal, I always feel a lot thinner. I'll eat more next meal and cry for losing weight every day, but I'm getting fatter every day!

It's a blessing to eat, hehe!
