I think the Slim Fast products are great to have when you're in a hurry and don't have time to cook breakfast or lunch, and they can be good for snacks. I use them a lot when I'm on the run, or if I'm having a chocolate craving I'll have a chocolate shake instead of a normal meal. But, for me personally, I don't think it is something I could stick to for life. You will eventually get sick of it...well, I know I would. So, I think if you want to use it to get started, that's great, but have a plan in place for when you eventually get tired of it. Start thinking of other meals and snacks for the same amount of calories. They are very convenient though, and if you can handle drinking those shakes for a long time and don't think you will get tired of them, it could really work. Any time you consume less calories, you'll lose weight, so if you're able to stick with it, go for it! Good luck!!!
