Hi /r/loseit, I'm making this post as motivation for myself to start the path to losing weight. I'm a male, 18 years old, 5ft 7in, and weighing in at about 179lbs now.
I have always been a little overweight, recently varying around the 160-170lb mark. In the summer of '10, I began to lose weight from around the mid to high 160's and got down to around the mid to high 150's. That didn't last too long as I began to go off that course and back into the mid to high 160's, occasionally low 170's for brief periods of time, until I would start watching my weight again. I fluctuated around this weight for a long time, and even up until recently, as recently as mid November, I was in the 160's. Things somehow soon went downhill, with a combination of incredible amounts of stress, and finding relief in partying and eating as much as possible. As I reach the tipping point of 180lbs, I just continually slip into depression about my weight and lose self confidence, which was already lacking before, which just adds on top of the incredible amounts of depression and stress I have about other things. All I really want is to start working out and get myself down to the goal of 145lbs, and fit. That's 35lbs, and gaining some muscle. I'm asking /r/loseit for just some support and tips, how to lose weight and gain some muscle. I'll start to put up some before pics soon. Thanks for reading.
