I think it's a good idea. I doubt Isaac will get sick if he selects his supplements wisely. I also don't think it will be difficult to do. I suppose to the average person it might be, but Isaac has already dieted down before so he should be adequately prepared for such a limited diet. BB.com carries a HUGE variety of supplements though, so it really isn't as bad as it may seem at first glance. Furthermore, the blog will be interesting content for the website.
