When It Comes To Weight Loss, Are Men Different?

I was reading an article criticizing how men are marketed to by the diet industry. My first though upon reading that was "I disagree." Men respond to different things than women, that is just reality. I was watching an ad the other day for NutriSystem For Men, and they were saying on the plan men could eat "Man Food."

That makes sense! Men don't want to eat tofu. And fewer still want to sit in a meeting each week with a bunch of overweight women. Weight Watchers has ads featuring men barbequing. Is that objectionable. Or do men tend to bbq. Might it make sense to develop a diet that catered to that?
