Gaining weight

We just arrived from our vacation and we gained a lot of weight maybe because we ate a lot of pizzas and gelatos in Italy :)Now it's time to shed all those kilos we gained.Have you heard about alli?Is it safe to use?I've been wanting to try to use a diet pill but I wanna make sure that I'll be safe when using it.

I know it's not good to eat these kind of foods,we even tried to refrain but it's really hard to do it.Maybe we just eat these kind of foods in a moderate way and also do some exercise to lose those excess weight that we have now.
