Yes, there is a 'magic bullet'. It's called methamphetemine. I don't recommend it. There are several other bullets out there that are helpful, but not quite 'magic', caffeine and ephedrine (ephedrine is a pre-cursor to meth). Healthwise your best bet is as TarpleyG said.
Start a journal. Write down EVERYTHING (calories, fat, carbs, protein) you eat every day. Weigh yourself every morning at the same time, naked, before you eat or drink anything. You starting goal should be about 1500 calories per day if you are about my size (5'9" and currently 260--was 315). I have done this a couple of times in my life and you will drop the weight, I promise. Eat every 3 hours if you can manage it but keep to your calorie count regardless. If you go over, skip breakfast or lunch the next day. Weighing yourself daily is that little demon in your head telling you he's watching.
I'll say that the calorie per day requirement varies substantially by individual. You might not lose weight at 1500 calories per day, or you might at 3,000. That is why the journal is so important. You need to determine exactly what caloric intake is keeping you at your current weight and decrease it.
There are lots of little tricks that will help you lose weight. Caffeine and ephedrine are both relatively safe and effective as appetite suppressants if
used in moderation, although both will increase your blood pressure slightly, so don't add them to your diet unless your bp is well within safe range. If you drink coffee anyway, time it so you drink your coffee a little while ahead of eating. Try eating foods that are more bulky for their caloric content (I used to make omelettes out of egg whites and fat free cheese that were only 300 calories or so that were large enough that I, a glutton by nature, had difficulty eating the whole thing). Switch to calorie free drinks. Diet coke is no worse for you than regular, won't rot your teeth, and 150 calories less each.
Green foods are your friend. In general, lots of bulk and few calories.
I lost 80 lbs and kept it off for five years with the "calorie counting" method.
