Empty calories refer to the amount of energy present in certain high-energy foods, which have low nutrients. In such foodstuffs, the energy mainly comes from the processed carbohydrates or fats and sometimes-even ethanol. Typically a clear chair calorie will support the equivalent energy as everyday calories but is poor rolling around in its nutritional benefit like lack of vitamins, minerals, amino acids, dietary fiber and antioxidants. Intakes of empty calories cause weight gain thus have to be avoided by those who wish to slim down. Some examples of foodstuffs with empty calorie content are carbonated drinks, jellies, soft ice cream, sweets, candy, margarine, white rice, white bread, butter, lard, alcohol consumption, beer, wine and fatty junk food like hamburgers, pizza, hot dogs, fried chicken, and French fries.
Are all calories good quality?
The fact is no; all calories are not good quality. It is a common myth inside the fitness world that fat loss or weight gain is only a few how many calories maybe you have consumed and just how many have your burnt; i.e. a calorie is the same whether it's extracted from proteins, fat or carbohydrates. But this is simply not the situation. For example; just consider two groups - Group A consumes 2000 calories from pizza, carbonated drinks, hot dogs and coffee while Group B consumes the same 2000 calories but from vegetables, fruits, chicken, fish and oatmeal. Now could you say Group B calories are superior to Group A? This is because the nutrients of the calories ingested by Group B is really a lot higher than Group, A which makes it different.
Does our bodies process all calories the same way? For example; 100 Cal pack vs. 120 Cal from your banana?
It was widely believed until recently that calories are processed and metabolized inside the same manner in our body. But scientific research shows otherwise; the body reacts very differently to calories based on its source and the way in which it is consumed. Calories from different sources like proteins, fat and carbohydrates offer a similar experience in their energy content but our bodies processes these in different ways. This is because our bodies needs to spend different numbers of energy to process and metabolize the various nutrients and calories; more energy is spent to process proteins than carbohydrates and more energy to process carbohydrates than fat. Hence, 120 calories from your banana add fewer calories to your body when compared to a 100 Cal pack.
Does our bodies digest calories the same at different times of the day?
It was considered that the years have absolutely nothing to do with the way the body digests calories thus you can get your meals at any moment of the day and never have to worry. But a recent study has revealed that there is indeed an improper time to eat. Though you can find conflicting reports, there is enough and more circumstantial evidence to prove that bad eating habits and wrong timings definitely affect our bodies inside the way it processes and metabolizes calories. Though the digestive process of the body remains the same, it's been noted that eating shortly before bedtime frequently brings about weight gain and also other digestive problems when compared to people who had an earlier dinner. But none of this has been confirmed completely and so the question still remains debatable.
