Whenever you are trying to lose weight, you should concentrate on these three things which all work together in providing a healthier and quicker weight loss goal for yourself. I have found this combination really successful in my weight loss plans. The first thing is exercising and how much you can put forth into it. The more you exercise, the more results you will see. The next thing is dieting and the calorie intake. If you exercise more, technically you could eat more? Always watch what you eat.
Now the last step in a good weight loss plan is always a good diet pill that can help you get to the end of the road. I have found Proactol which is a natural herbal diet pill to be the best around. It's an appetite suppressant along with being a fat blocker which stops up to 28% of fat you eat. Read up about it at TheWeightLossPlace .com where I saved money on it. Proactol really works well with exercising which gives you plenty of energy to perform. Along with that you diet will be affected by Proactol due to the appetite suppressant and fat blocker. If you slip up on meals, the fat blocker kicks in. It's really great to stop food cravings.
Concentrate on those three things and the combination is deadly for the fat cells in your body. Good luck and I hope this helps.

that is a great way to slowly improve yourself
i applaud you b/c most people would jump right into the running and its those people that end up stopping early
but you plan is seriously a great idea.. it will take a while w/ this plan to see weight loss but it will definitely work in the end.
esp if you continue it through the summer.. you will b a new person by the new school year
