I'm against. Calories in calories out.

 Taking those pills are like slow-poisoning yourself. Those pills have many harmful effects, Even if they help you to reduce weight they will surely make you weak too
Do exercise a lot, eat healthy diet & you will feel more healthy, strong, active & fresh.

 They are harmful

 If you take diet pills most likely they will work ,but the downside is that as soon as you stop taking them you will gain back the weight and then some

 Eat healthy and exercise/and once in a while eat some junk/but pills contain chemicals and many other harmful things that you do not even know what they are/these things can be harmful to your health maybe not now but later

 No they aren't any good for you, most of them are just empty placebos, and others are laxative like, there isn't anything that can help you to lose weight more effectively than good old fashioned exercise and healthy eating.

 Exercise is good. Pills just proves how lazy people are when it comes to losing weight. If you work out more than you shouldn't be over weight.

 Eat healthy and forget the diet pills. They can cause health problems.

 Diet pills usually have side effects, it will damage your health more than benefiting it. I advice you to eat healthy food & do sports..... Exercising is the most IMPORTANT way to lose weight. It worked with me !

 I think if you are gonna bite the bullet in the first place and gain tons of weight from fatty foods you should eat it too and work it off naturally.

 Diet pills are not healthy. They run up your blood pressure and can make your heart beat faster than normal. Also if you do get a pill that helps, when you stop taking it the weight will return most of the time.

 This is a question, not a debate. It belongs in Q&A.

No, diet pills are not good for you, but for the most part, they don't work. If diet pills really did what they say they will, don't you think doctors would tell their overweight patients to take them?

You might recall a prescription medication call Fen-phen that was hailed as a weight loss drug until it was determined that it caused valvular heart disease and pulmonary hypertension, mostly in women. It had to be pulled from the market because of the damage it had done.

If you watch the TV commercials that push diet drugs and tell us you don't have to change your habits, you should take a look at the small print on the screen. It says the pills should be used in conjunction with a plan of diet and exercise. When they show pictures of people who have lost weight, there is usually a qualifier on the screen that says "Results not typical". If one follows a diet and exercise plan, why do you want to spend all that money for some worthless pills? The same goes for the meal plans that cost hundreds of dollars a month.
