As a clinical RD, I have to lump people into categories all the time in the hospital based on a primary diagnosis - COPD, Diabetes, Renal Disease, Cancer, Stroke, Heart Attack, Small Bowel Obstruction, Pneumonia, etc. But after the diagnosis, everyone is different - everyone has his/her own past medical history, medication list and treatment plan which affects how the patient is treated.
If you are treating this as a meal, enjoy 1 or 2 omelets. But if you still need something small before you eat another meal, how about a piece of fruit and a few nuts or 1/2 cup 0% Fage greek yogurt.
1 bunch kale
Choice of fresh bread
Onions, Tomatoes and Red Bell Peppers
