HI! I am an MS1. There is no need to worry about the height and weight until you receive an interview. If you do get interviewed, you will get a bunch of paperwork underlining the service preference, security clearance, and DoDmerb health screening. That is when height and weight will matter. There are regulations with height and weight but even if you don't meet the weight you can be tapped and still pass. Tapping is quite lenient but continue the healthy weight loss! Finding healthy ways of keeping your weight low as opposed to fast and quick methods will keep you ready for staying healthy in school as well.
