If you're at a desirable body weight and have plenty of energy, your calories in food intake is probaly ok. However if you're gaining weight and feel tired a lot of the time, you may want to consider counting your intake of calories in food and changing your daily diet, because as you ingest extra calories your body will convert the excess energy to body fat and this will lead to weight GAIN !!!!!
Try estimating your own energy requirement so that you will be aware of the food that you take.
