I'm 1 year out and would not be able to consume "½ cup fat-free cottage cheese and a green salad with 3 ounces of canned light tuna" in one sitting. I could choose the cottage cheese OR the tuna, but would over-fill my sleeve. I use a scoop of chocolate whey in my coffee in the morning as "creamer" and usually take a solid bar of some kind between lunch and dinner. They allow me the flexibility to eat a better variety of foods rather than strictly a chunk of grilled meat or some tuna or 1 egg. I still choose protein first at meals, but supplements allow me to mix in other foods as well. Plus, I've found ways to take them where I enjoy the supplement its self and would miss it. The coffee makes a nice mocha latte and a PowerCrunch bar fills my need for a "cookie" with something that has some food value for me. If I get busy and miss a meal, at least I know I've met my minimums for the day.
