Hi Taina! I have a similar problem, I'm 5'5 and i weigh 180 pounds and i would like to lose it fast, too. Right now, I'm giving Slim Fast a try and it's satisfying, not making you feel hungry. My mom has a new diet she is trying and she lost 6 pounds in 3 days! So if you wanna give it a try, email me at pumpkins623@hotmail.com and I will give you the information. All the diet is is a list of food that works on a chemical breakdown and is proven to work. It is free, and if u email me, I'll give u the food list, and the rest is up to u!
