Much like asking what's the best oil to use in your truck, a diet thread will bring out the know it all's from every camp.
I used medifast about 4 years ago with great results. However, it is very expensive and most of the food tastes like vomit.
For the past 9 months, I have focused on very low Carb, multiple small meals a day. Find what works for YOU and make it happen.
