Yes, you do need a certain number of calories just to keep your heart beating. My point is that once you already have all the calories you need it would be too bad if you needed to keep eating in order to get all the nutrients that you need. That is why it is favorable to eat red meat. You are correct when you state at the beginning of your second paragraph that people on meat-heavy diets tend to eat fewer calories. But you are incorrect when you state at the end of that paragraph that a plate full of plant food will have fewer calories than a plate of meat. If this were true, then people on meat-heavy diets must not be finishing their plates of food, since they end up consuming fewer calories. As for your own diet, it's a good thing you have the eggs and cheese in there! That's where your vital nutrition is coming from. The rice and beans and veggies are just keeping you alive with calories but not carrying their weight in terms of nutrition. You could be doing worse, such as eating a bunch of bread and pasta, or even worse than that, soda and candy, but you could also be doing much better by eating mostly steak and sardines.
