For example, there are four calories in a gram of carbohydrates, four calories in a gram of protein, one gram of fat has nine calories and a gram or alcohol has seven calories. It also depends on the cut of meat, the toppings you put on food, whether it is low fat like a bagel or high in fat like hamburger. Just remember that all foods provide calories and all calories provide energy. But not all foods provide the right nutrients to the body such as vitamins, minerals, fiber, amino acids and fatty acids. Many foods provide empty calories or naked calories, which mean they do not give any beneficial value.
Empty calories can contribute to being malnourished or overweight.
All calories will give you weight but how you spend those calories determine whether you gain or lose weight. If you burn up more calories than you took in by exercising or another activity, then you will lose weight. The same holds for gaining weight. The more calories you take in during the day, but do not burn up through some physical means, will produce weight gain. So, be conscious of what types of food you eat, how many calories are involved, how many calories you personally need during the day, and how much activity you need in order to burn up those calories.
