Just a thought, there is nothing wrong with a catchy title but depending on what your intention is for the blog you might want to scrap clever and go for keyword rich. If this is just for your friends, then clever is good, but if you want to ultimately attract attention from search engines and are not planning on spending a ton of money on SEO then having a name with some good weight loss related keywords in it will help you out a lot when it comes to getting search engine rankings.

If income is the ultimate goal I would search for the free google keyword tool and type in weight loss, fat loss, diet tips, or whatever else makes sense and then copy all of the keywords that the tool suggests (one click download to a text file) and then go over to godaddy and use the bulk domain function (in the domain tab) and enter them all in and hit search. This will show you if any of the commonly searched keywords in your niche are available as domain names. If they are not, broaden your root keyword from weight loss to something longer like weight loss diets, and so on.

But if this is just for fun then clever is great.
