Is it smart to watch what I eat and only have 2 meals a day? What should I do about my weight?

You're 15 years old?
Ear the hell out of everything you can. At your age restricting your calorie intake can have detrimental long term health effects. There is no maximum weight limit, the services go off of body fat. The weight tables you're thinking of are screening tables. Basically, if you're below X weight at X height, your body fat % is below the requirements. If it's above X weight then you get taped. If you are eating healthy and staying active you're fine. If you don't have a noticeable belly then you're definitely within tolerance.

Zachary Lindsay Google AR600-9. It will give you the height weight tables and Body Composition Requirements. Your recruiter can help you on understanding weight standards. If you fail height weight, they do body composition with a series of measurements and spin a wheel and your body fat is calculated. You have an alloted body fat by age and gender. Sometimes it's fair, sometimes not. It is what it is. You'll learn your numbers you have to hit to be in standard.

It's good you are in shape. It doesn't matter whether it is muscle, fat, grizzle, loose skin, cartilage, or wrought aluminum. If you bust tape, you'll be entered in the ABCP and have to make satisfactory progress to get in standard in 6 months or you get separated.

Being a big moist guy my whole 22 year career was a struggle. Get in shape, stay in shape, protect yourself from injury.

Best to ask your physician.

That said, here's what my doctor told me. One of the keys to better appetite control is to keep your blood chemistry levels (blood sugar and insulin) relatively stable.

Dietary fiber, and lots of it, help with both blood sugar and insulin stabilization. Eat lots of raw vegetables high in dietary fiber with every meal and eat them first in the meal. Once you've finished the raw vegetables, take about 5 minutes to enjoy the good company at the table to give your gut the time to get in the best digestive mode.

Eating small meals more often, rather than bigger meals less frequently is best.

If you have not been physically active during the day, a brisk 15 minute walk 30 minutes after the first and last meal of the day also helps stabilize blood chemistry.

Following these three principles, I lost most of the spare tire that started to develop in my mid-30's, while still eating pretty much anything I wanted.
