Hi OK... so currently I weigh about 142lbs and I'm 5"2 and 15 years old I consume around 400-600 calories daily I eat breakfast and dinner and very rarely a snack and I also drink roughly 2 cups of coffee and 5, 500ml of water but for some odd reason I occasionally gain weight I'm quite an active person I hardly sit down I'm always standing and reading a book I usually sway whilst doing so I pace as well I do go for walks and I have currently for the past three days been shoveling up stones and racking them. Please help me I need to lose 13lbs before October the 22nd if that isn't possible I would hope for at least 8lbs as it is my dream to reach my goal by my birthday I hope I gave enough information and sorry if it is jumbled up
