Glucose that is not needed for energy will be converted into a glycogen, a form of stored glucose found in the liver and muscles. We have a limited ability to store glycogen. An average adult has just over 100 grams of it in the liver and about 250 grams in all the muscles combined. Once a carbohydrate is converted to fat, it can never become a carbohydrate again. If there is a balanced variety of fruits, vegetables, grains, legumes and soy products in your diet, the occasional presence of meat is not a problem.
Meat is a good source of many nutrients.
Personally, I tend to mix vegetarian days with omnivore days. I go for the variety of flavors, tastes and textures. Send questions to him by clicking here.
