There really are no good weight-loss drugs. Anything that causes your heart rate to speed up and your body temperature to rise unnaturally are not only detrimental to your health, but won't fix your eating habits in the long-run. Anything that makes you jitter from amphetamine or have heart murmurs or gives you diarrhoea is not "good".

Low cal/low fat/high carb diets are metabolically destructive, but at least with low-carb, if you follow it properly for the first couple of weeks (Atkins induction) you only need to have "willpower" for those first few days until your body slips into ketosis. After that, appetite will decrease and you'll find it naturally easier to stay on plan. No more empty stomach growling, plummeting/rising blood sugar making you feel faint and causing cravings. If you do it properly, it WILL make things easier on you.

But PLEASE don't try and go down the route of using diet pills. They're not good for you and they won't give you the results you want long-term. In fact, there's more of a chance that they'll mess you up metabolically, so bad, that your body just refuses to cooperate on ANY weight loss plan you then start to follow. Not to mention the subsequent heart problems they cause. Going low-carb will make your body healthier and happier. Pills could very well make you ill, or at worse prove fatal. Just make good informed choices, stick to a plan and you will be healthier for it.
