I follow this approach in the warm weather. Because they are used in medically supervised diets, I use the HMR replacement shakes. To me they taste good and the only downside is the cost. My friend went to the actual hospital based program and she did really well using their products.
There are probably others out there with the same nutritionals but I took the easy way and just got these online. They work but I only can do it in warm wether as in the cold a shake does not appeal to me.
I would like to know if anyone else has found a good tasing healthy shake for a reasonable price.
Good luck. I am personally not a fan of slimfast-taste metallic to me.
