Hi Macky,
Because I've tried those fad diets when I was at your age.. wow that was long years ago.. and for few weeks it made me lose weights. Like more than 10 pounds but gained it back as soon as I stopped.
So I did some reading and research.. and found out that the culprit of all these weight gain is sugar and processed food.. since then I stopped eating that contains high sugars, refrain from drinking that contains sugars. I stick to natural or organic foods.
You can do it sis.
