please help me

I wouldn't be so quick to jump to diet pills. Have you been to the doctor to see if you have hypothyroidism? There could be a medical reason, because if you're working out everyday and gain back your weight quickly, it sounds like you have a slow metabolism. You should check with your doctor/physician and have your thyroid checked out, and also go over diet plans. I wouldn't jump to pills though, they aren't exactly healthy and could even make you worse.

i think i would wait on the pills and keep working out and if that don,t start to work then you may want to go see a doctor.

Try try and try till you reach your goal.You will certainly loose weight if you are aware of what you eat and do exercises to control your weight.Do not be anxious,follow a good meal plan and exercise regimen.

WEIGHT LOSS TIPS:
Simply follow four principles in your life and you will be soon reducing your excess fat from your body.

1)When you wake up in the morning don't go for coffee or tea,instead have a bowl of fruit of your choice.

2)Have smaller meals every 2-3 hours in a day,that make something around 6-8 small meals.This will help you stay full and continue to supply energy at regular interval of time.

3)Have your meal according to your days activity eg. if you are doing strenuous activity (exercise,working) go for high protein and carbohydrate food.And if you are sitting idle,chatting around or watching movie go for low protein and carbohydrate meal.

4)Go to bed after 2 hours after having your dinner.Let all the food get digest within these two hours then have a good night sleep.

These are very simple steps but very difficult to follow,but if you get with it then you'll never face weight problem.
