diet with friends

So my friends and i are talking about losing those stubborn fats. Even the husband is "serious" with it. He started eating salad at night this week and so far so good. Hopefully he will get some good results with it. I've been trying for so long with little or no success. I am soo tempted to take those safe diet pills that work or so they say. I don't really know what else to do! really desperate here. buhu :(
