Get a article submitter and a blog network for best results it might cost around $300/month for the good ones but it is well worth it. Make sure there is no duplicated content on your site get a facebook fan page. Make a good solid link building plan such as link wheels and link pyramids make sure that the content on your blog is really really good free content that people would normally pay for and then tell them to buy the ebook or the whatever product it is and let them know that it is better then the free content.

According to me weight loss is a very competitive keyword and you have to work real hard to rank for that keyword. Now that you are a noob and want to start a site on weight loss, do keep in mind the panda and penguin updates which could pose problems if you follow old SEO strategies.
