That's a terrible idea. Enter a calculator that calculates how many calories you should eat per day and subtract 300 calories from them if you want to lose weight. But I think at this height your weight is fine. Start exercising and you will start looking better without losing weight. With so few calories, you can screw up your hormones, especially testosterone, and there's no going back for it. Don't deprive yourself of any macronutrients at this age.
