So the ideal goal should be to eat healthy food without making it a chore. Being a vegetarian, meals could be filled with spicy lentils, lip smacking vegetable curries, fresh breads, yummy pizzas, flavorful noodles, aromatic soups. Being vegetarian and hungry at a conference in the West would entail eating some salad (non filling), skipping the beef broth containing soup, skipping the bacon loaded potatoes, layering gobs of butter on some bread, and filling up with loads of dessert! Years of professional meatless meals like this and similar food on flights take their toll. You end up with cholesterol, triglycerides, inches, pounds and no idea how you got there.
