Hi Volt,
Let me tell you FROM EXPERIENCE that by starving yourself or trying to make yourself throw up.. it won't work. Your body is designed to
retain fat during a time of famine so if you stop eating, you may lose weight at first, but then it will STOP. Also, your stomach acid can hurt your stomach if you dont eat or your whole digestive track if you throw up a lot. If you starve long enough, your stomach will become intollerable to food.
You can definately lose weight at home, thats what I'm doing. I got a tred mill someone else was getting rid of (the fad went out

) and I also bought a home gym that was on sale for like $120. Great investment! And it will all last forever, and if you don't like it, you can resell it. Or just get a few free weights and take the dog for walks around the neighborhood. But you don't have to get bored! If it snows where you live, buy a pair of wooden snowshoes and hike with them or go to a local lake and rent a boat and row for a while. Put your weights in your basement, so you'll have privacy if you dont like the gym
Also, don't lose weight to impress a guy, do it for yourself. If he likes you for your body and not your personality, dump him
He should support you if you want to lose weight.
