The fact that you want to do this without your mom knowing tells me that you want to do things that you know are not healthy for you.You don t need to lose 45 pounds, and certainly not in 4 months. If you talk to your mother and work with her to make a sensible exercise and eating plan you will be much more likely to be successful.The first thing that is not healthy is the 1000 calories a day. You probably won t lose anything, and you will probably gain weight, because your body will go into starvation mode, which means that it will conserve, and try to hang on to every calorie you consume. Your brain will think you are starving, and will try to prevent weight loss and will hold onto fat. You will also lose your energy for any type of exercise, you won t be able to concentrate, and you will damage your internal organs. You will be setting yourself up for failure it you do that. Even on the strictest diet you need at least 1200 calories a day, and more likely 1500 calories a day, if you want to lose weight and keep it off. You are setting yourself up for failure.Listen to your mom.http://kidshealth.org/kid/stay_healthy/f��
dont hide from mum...i think she would be proud of you if she found out what you were up to...you are still 13,so stay active in dance,sports and martial arts...get a dog and take it for 20 minute walks twice daily(thats my favourite cardio,that also keeps my dog healthy!)...avoid all sugary drinks,fastfoods and junkfoods...you can eat as much veggies and fruits as you like but do get protein from beans,tofu,raw nuts and dairy foods...
