I'm 19, 5"3', female, and weigh 120. For the past at least five years of my life, I've been eating 1,200-1,500 calories, which leaves me feeling satisfied, energized, and maintaining my weight. I've been eating a very healthy vegan diet, and have eaten pretty healthy my whole life.
I feel like I'm eating enough, and I'm maintaining my weight, but our "experts" say I need to eat more. I feel like if I ate more, I would just gain weight, but I'm at a healthy weight now. I exercise moderately.
