Empty calories make reference to the volume of energy contained in certain high-energy foods, which have low vitamins and minerals. In such foodstuffs, the vitality mainly arises from the processed carbohydrates or fats and sometimes-even ethanol. Typically an empty calorie will offer the same amount of energy as standard calories but is poor in their nutritional benefit like deficiency of vitamins, minerals, amino acids, soluble fiber and antioxidants. Intakes of empty calories cause fat gain thus has to be avoided by dozens of who wish to lose weight. Some examples of foodstuffs with empty calorie content are soft drinks, jellies, frozen treats, sweets, candy, margarine, white rice, white bread, butter, lard, booze, beer, wine and fatty processed foods like hamburgers, pizza, hotdogs, fried chicken, and French fries.
Are all calories good quality?
The fact is no; all calories are certainly not good quality. It is a common myth inside the fitness world that fat loss or fat gain is simply a matter of how many calories have you consumed and just how many have your burnt; i.e. a calorie is identical whether it's obtained from proteins, fat or carbohydrates. But this is simply not true. For example; just consider two groups - Group A consumes 2000 calories from pizza, soft drinks, hotdogs and coffee while Group B consumes exactly the same 2000 calories but from vegetables, fruits, chicken, fish and oatmeal. Now could you say Group B calories are better than Group A? This is because the vitamins and minerals in the calories ingested by Group B is much more than Group, A which makes it different.
Does your body process all calories exactly the same way? For example; 100 Cal pack vs. 120 Cal from your banana?
It was widely believed until now that most calories are processed and metabolized inside the same manner in your body. But scientific studies have shown otherwise; the body reacts very differently to calories based on its source and exactly how in which it is consumed. Calories from different sources like proteins, fat and carbohydrates are similar in their energy content but your body processes each of these in a different way. This is because your body must spend different levels 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 in your body when compared to a 100 Cal pack.
Does your body digest calories exactly the same at different times in the day?
It was thought that time has nothing to do with the way the body digests calories thus you'll be able to eat out at at any time in the day and never have to worry. But a recent study has said there exists indeed an improper time for it to eat. Though there are conflicting reports, there exists enough and more circumstantial evidence to prove that bad eating habits and wrong timings definitely affect your body inside the way it processes and metabolizes calories. Though the digestive process in the body remains exactly the same, it has been noted that eating late into the evening frequently brings about fat gain and also other digestive problems in comparison with people that had an early on dinner. But none of this has been confirmed completely and the question still remains debatable.
