I am posting because of the fact that she is a West Point grad, as is her husband, and she has no skinny friends, well at least not in the wedding party.
You should've seen some of the Marine wives out in 29 Palms (shudders). Granted, I get what you're saying about West Point, but it's still the military. So don't except runway models as far as the women are concerned. And her friends are all probably from (insert small town U.S.A) and spend their Friday and Saturday nights having the locals buy them pitchers of Bud Lite. Life is good for them and they don't give a damn about their weight.
I thought the military was about staying in shape
You'd be surprised. Even in my infantry unit there where some men who let themselves go. Granted deploying to Iraq in the early '00's for multiple tours will take a toll on your body, but I never thought of that as a valid excuse to become a fat body. Don't get me started on non combat units.
This article about Lt. Gen. Stanley A. McChrystal taking over command of Allied forces in Afghanistan is from 2009, but it really sheds some light on how soft our military has become.

For all the rigor of basic training and the strict abstemiousness and discipline of military life, the American military is not, by and large, an ascetic institution. Comfort, though not the top priority, is also not systematically rejected. You can buy a latte at many military bases. No one is required to sleep on reeds. And yes, the Pentagon wants its troops to eat. Indeed, a 1995 study was conducted by the Institute of Medicine to determine why American soldiers tended to under-eat during training and in the field. Lack of choice in food — surprise — was a major reason.
Love him or hate him, when I think of a modern day warrior and leader, McChrystal comes to mind.
