Originally Answered: Is what I ate today healthy?
Was it healthy? Yes. Was it enough food? No. The minimum amount of food you want to take in is around 1200 calories, and that is for someone who sits on their butt all day and does nothing. If you walk anywhere, climb any stairs, or pretty much do anything you will be burning calories, therefore, you need to eat that many more calories just to balance energy expenditure. Your body burns many calories for normal biological processes. Put it this way, anorexics have far more health problems than someone who is pretty overweight (notice I didn't say obese). Google a calorie counter to figure out how many calories you ate. Better ones will tell you what percent of carbs, protein, and fat. A normal recommended amount of fat is 30% of your daily caloric intake. You need fat in your diet, protein, and carbs. Your brain only uses carbs. Your muscles use protein. And fat is used for making and repairing cells as well as protection for your organs. These are just the basics. Eating too little will kill you faster than eating too much.
