I am a 13 years old girl. I weight 56 to 59 km ( which goes up and down) and my height is 157cm. I had tried to diet before it works and my weight went down very fast but it doesn't last so long then it came up again. I usually eat vetgetables for my diet as well as tofa and i would usually run for 2 km a day. I want to lose weight so can anyone give advice that will help me pls? thank you everyone
