I’m 15, 5’4 and 120. Last week at our school we had secret santa. It was very nice and all but I put on 3lb’s (we only really give and get sweets) and my body is now always hungry. I’m worried that if I diet too quickly my body will go into starvation mode and get even fatter! Any ideas on what I can do? And I do need to lose the weight so if anyone could give me a diet or a meal plan or anything. And before some advert comes up, I already take acai berry! Thanks!
