I found this to be an interesting article.

I'm A Man, And I've Spent My Life Ashamed Of My Body

When I was young I was always short and skinny. As far as appearances go, I've always been a turd (been called ugly more times than I can count). Now that I'm on antidepressants, I'm short and fat. If I eat over 1500 calories per day, I gain weight (and I'm not allowed a day to eat 2000 calories or I gain). I lifted weights and dieted like crazy during my 30s and at my best I was about 175 lbs and 10-12% body fat; not exactly Men's Fitness cover worthy, but enough to not feel like a puny loser. A combination of job change and finances and I dropped back to 155 and 18% body fat and have only gotten worse (195 lbs now and too-much% body fat).

That said, they can add me to the list of guys that doesn't like his picture taken, always feel I could lose (or gain) weight and would trade 2-5 years off my life for a perfect body. I've never looked in the mirror as a whole except as a psychological exercise. I only make sure my beard is trimmed right or I don't have a big zit, never to see what's really there.

I think more men have body image issues than we begin to perceive. Maybe it's time to start talking about it instead of arguing over "dad bods".
