I had this problem not to long ago. The way that worked for me was I did rigorous exercise and I stopped drinking carbonation. No matter what I would not recommend drugs.

firstly no good medication for weight loss, all contain super high levels of caffeine and loads of crap that your body wasnt meant to naturally consume, then mixing that with healthy fod just binds the two and creates a mess that your body will react to once you are off the medication and put more weight on.
Try just a healthy food diet accompanied with reguarler exercise.
Consume less carbs (pasta, rice, white bread etc) and consume more protein and fibre.
eat 5-6times per day but smaller portions of fist size and make sure your smallest meal is dinner as this is when your metabolism is slowest (metabolic rate reduces as the day goes by)
combine your workouts with strength/resistance prior to cardio this will benefit you more. aim to exercise 4 times per week with rest periods between. check my blog for more recipes and workouts if you like http://myfitmate.blogspot.com/
good luck

drugs aren't good for losing weight. you gain it back immediately when you go off them, and they're only slightly effective anyway. 99% of them have no effect on weight loss at all.
foods are easy, low fat/whole grain/veggies. eat simple.

Start a diet - Winter diet is fine
Exercise - it can be just walk (5 km per day at the beginning), run, dance,swim
Change the diet after two weeks - start new one, continuing exercising. The secret is the body not to get used with the particular diet
Do not give up if you do not lose weight as fast as you want. The body needs time to react.

Ive been on the CSIRO diet for a few weeks & lost 4.5 kg with not too much effort. Feel alot better than before.
I love it as the weeks meal plans are done & shopping is easy. The books are cheaper at BIG W.
Diet pills are a waste of money & are bad for your health.

sports and healty food no junk

There are NO miracle pills. Don't believe everything you hear about diet pills. They only suppress your hunger, but you NEED TO EAT in order to lose weight.
You have to exercise, and eat healthy. Eat 4 to 5 small meals a day. Eat breakfast every morning to start your metabolism, then have your other meals spaced throughout the day.
NOT fast foods or garbage foods but healthy, good for you foods.
It takes time, but this is the correct way to lose weight and keep it off.
Binge dieting is guaranteed not to last.
