<human>: Can you succinctly summarize the text in 1-3 sentences?

Five years ago, when I was a Sophomore in High School, I went to my first Districts meet in swimming. I saw all of these very in shape people around me, and here I was; 5'10, 215lb all body fat. On the way home from the meet, I suddenly said to my dad, "I want to start taking a weight loss pill." He set me on the right path by basically telling me that that was foolish, and got me in the gym where, over the next three years (up until the middle of swim season my freshman year in college) I dropped all the way down to 160lb, 6'1". It is now the end of my Junior year in college, and I am 6'2" and 195lb. While I have put on some muscle, I have also put on fat.

This is where I begin again. I am looking to drop down to 175lb without losing muscle mass this Summer. I say all this, again, because I am looking for support. I am also looking for a reccomendation; how do I control how much I eat? As a swimmer I am so used to consuming 3500+ calories a day, and out of swim season that just doesn't work.  I have read such inspirational stories on here, and I am hoping to keep reading about the successes of the Lose It members.
