I am a guy that cares about my health and looks and want to lose weight but almost every commercial I see for weight loss is only meant for women such as diet pills, diet food plans, and gyms/weightloss centers. Why don't they have stuff for both men and women or at least have the same amount of stuff focus on men's weightloss?

hydroxycut, good product, gears towards both. so does lipo-6. i think its just the tv ads that you are getting this interpretation. if you pick up any issue of "Flex" magazine, or "Muscle & Fitness" and you will see all kinds of ads for men.
Woman watch more tv during the day, house wives, then men do. thus, it would be good marketing that they are geared towards woman.

Traditionally, its a male dominated society we live in and as such we have created this image of what the female form should look like. Some women are literally killing themselves to reach that ideal with dangerous practices like bulimia.
It's not just weight loss either - look at women's shoes. How impractical are high heels? And they're lousy shoes that don't hold up to boot (no pun intended) typically a man's dress shoes will last a couple of years, women's will last one season if they're lucky, but they continue to buy and wear them because it makes their legs look longer and what society dictates as more attractive.

Women are more insecure about themselves and care more about how they look.

people are more focussed on how women are supposed to look and the american businesses feed off that. women will complain over and over how they they're chubby or big boned and move on, but women will dwell on it until they change. It's just america catering to what will make them the most money. i don't know too many guys that would own up to taking a diet pill because it's seen as unmanly or something.

Woman have a harder time loosing weight because they are women. These groups focus on where the money is.

you know the answer to this question if you live in American or any westernized nation
