Is there any pill to reduce obesity?

Diet pill: This is a repeat of what I have said before. My philosophy is that the best way to lose weight is not by dieting or a pill, but by changing your lifestyle to a healthier one. You don't need a drastic diet. Make small changes. Eat the right portions, eat 3-5 small meals a day, cut back on carbs and sugars, increase lean protein/veggie/fruit/water intake, & start doing some cardiovascular exercise.

Yes: There are several medications approved by FDA for weight loss such as Phentermine, Qsymia, Belviq, (lorcaserin) Diethylpropion, Phendimetrazine; there are several new ones in trials. These drugs suppress appetite. We still have to eat a well ballanced healthy diet, exercise regularly and change our behaviour towards food.
