Diet on December?

Dieting is really a big question mark on me nowadays specially holidays is here. December is time for eating and I know, a lot will agree with me here! Honestly, I've gain so much this couple of months and my mom is always nagging at me because I don't look good anymore. I know, she is just concerned with my health and I do appreciated her thoughtfulness. I told her that I will go back on strict diet again and this time am thinking of using some weight loss pills to easily discharge the fats on my body.
