You'd be shocked at the number of dangerous and dubious items that are sold as diet products nowadays. People searching for a healthy way to lose weight are bombarded by all kinds of curious concoctions — supposed secrets of the orient, or whatever — that claim to allow them to lose weight the healthy way. The reality is, you have no way of knowing what's really in these products.
Many of the "healthy ways" to lose weight actually put a tremendous amount of strain on your body. Using some new — or not so new — fad such as the Atkins diet, which requires you to eat ridiculous amounts of fat and protein, is not a healthy way to lose weight. If this is not immediately obvious to you, look at the research. Many experts have linked the Atkins diet to liver problems. Weight loss should be beneficial for your heath. It should not threaten it.
