Empty calories make reference to the quantity of energy seen in certain high-energy foods, which may have low nutrients. In such foodstuffs, the energy mainly comes from the processed carbohydrates or fats and sometimes-even ethanol. Typically jail calorie will retain the equivalent energy as standard calories but is poor in the nutritional benefit like deficiency of vitamins, minerals, amino acids, fibers and antioxidants. Intakes of empty calories cause fat gain and hence has to be avoided by those which shed weight. Some examples of foodstuffs with empty calorie content are soft drinks, jellies, soft ice cream, sweets, candy, margarine, white rice, white bread, butter, lard, booze, beer, wine and fatty processed foods like hamburgers, pizza, sausages, fried chicken, and French fries.
Are all calories good quality?
The answer is no; all calories aren't good quality. It is a common myth in the fitness world that weight-loss or fat gain is simply matter of how many calories have you ever consumed and the way many have your burnt; i.e. a calorie is similar be it obtained from proteins, fat or carbohydrates. But it's not true. For example; just consider two groups - Group A consumes 2000 calories from pizza, soft drinks, sausages and low while Group B consumes the identical 2000 calories but from vegetables, fruits, chicken, fish and oatmeal. Now do you say Group B calories are better than Group A? This is because the nutrients with the calories ingested by Group B is much more than Group, A so that it is different.
Does one's body process all calories the identical way? For example; 100 Cal pack vs. 120 Cal from your banana?
It was widely believed until recently that every calories are processed and metabolized in the same manner within our body. But scientific research shows otherwise; our own bodies reacts very differently to calories determined by its source and the way in which it is consumed. Calories from different sources like proteins, fat and carbohydrates are similar in their energy content but one's body processes all these diversely. This is because one's body has to spend different numbers of energy to process and metabolize the different 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 than a 100 Cal pack.
Does one's body digest calories the identical at different times with the day?
It was considered that the years have nothing to do with the way our own bodies digests calories and hence you'll be able to get your meals at any time with the day and never have to worry. But research conducted recently has revealed that there exists indeed a wrong time for it to eat. Though you'll find conflicting reports, there exists enough and more circumstantial evidence to prove that bad eating habits and wrong timings definitely affect one's body in the way it processes and metabolizes calories. Though the digestive process with the body remains the identical, many experts have noted that eating late into the evening frequently contributes to fat gain as well as other digestive problems when compared with people that had an earlier dinner. But none of this has been shown completely therefore, the question still remains debatable.
