a suggestion on how to monetize effectively - eliminate the 'home' and replace it with a couple of pages that detail the following:
1. why should someone be worried about their weight? this will 'scare' them out of complacency(sp?) and get them to think about making a change
2. diet pills - while you might not personally support their product, but at least act like you do. for example, just because you think the above mentioned 'proactol' isn't good, it pays a nice commission, so unless you have an overly strong sense of moral duty, that would be what i would try and convince the overweight reader will help them best. give them other options - hoodia, etc..., giving an objective opinion, and then tell them what their best choice would be
3. wieght loss programs - again, present the user with options - they want to feel like they are in control. if you give objective information with which to base their decision on, they will be much more apt to buy a product via you, and possibly even the one an 'expert' such as yourself recommends
This is probably a good starting point for a better converting site. I think what you have looks good, but the adsense up top looking the way it does sort of drains credibility from your site. More importantly, if you have drawn a visitor to your site - why 'sell' them for mere pennies or a few dollars when you can possibly get them to buy something that is what they are looking for, and will pay you a nice commission.
I think that should help. It sounds as if myowndemon has some good offers to promote for you. Keep this in mind though - that proactol probably costs a lot of money to the buyer, and probably won't convert anywhere near where something like a $4 7 day supply of HOODIA would. Obv, one pays much more, but this is all stuff that you can test once you have a few different affiliate offers to promote.
best of luck
