When I moved to my new neighborhood in second grade I lost a lot. Mostly, I lost my willingness to go outside, because I was one of the oldest kids in the neighborhood & everyone else was starting their families so kids were like 1 or 2. I was super skinny then from playing all the time, but when I stayed inside I gained a lot of weight.
Not all of the weight was because I shot up to 5′11″. I gained about 100 pounds since then. I’ve been overweight as long as my friends in my new school system can remember.
Now that I’m in high school, I want to seriously change. I don’t think like a fat person; I look at girl’s clothes & think they’re cute, then remember I’m fat & can’t wear them. I bum myself out all the time.
I’m eating two meals a day. I make sure I eat the required fruits & vegetables, & only drink milk & apple juice (I HATE pop)
However, since I started this diet I’ve been having diarrhea. On & off for a couple months. It hasn’t been explosive, but going to the bathroom has been harder. I don’t think it should be lack of fluids, because I substitute my hunger with liquids a lot.
Why would I finally be having problems when I’m eating healthier?

I have a great diet where i only drink water all day & eat the healthy stuff & i am toned because i exercise alot, still i just wanted to get a bigger. People tell me i have a nice body but i’m still slim. Thing is i don’t wanna just start eating anything & everything because it can greatly ruin my already healthy diet.
ANY SUGGESTIONS?

I went on a high fat diet & raised my cholesterol level now I am worried about my heart. How can I fix this fast, I am only 29 years old. I need a heart healthy diet plan.
