Health and diet questions are two different subjects for your doctor. Oftentimes the diet question is answered in evasive terms. Eating a wide variety of food groups is optimum. Cutting out one group can be neglible for any of us except if we have allergies or other aversions to it. Losing weight should be low and slow. It took umpteen time to gain it, why be in a hurry to loose. Your body suffers greatly.
