Empty calories talk about the volume of energy contained in certain high-energy foods, which have low nutrients and vitamins. In such foodstuffs, the energy mainly comes from the processed carbohydrates or fats and sometimes-even ethanol. Typically an empty calorie will retain the same amount of energy as ordinary calories but is poor in their nutritional benefit like not enough vitamins, minerals, amino acids, dietary fiber and antioxidants. Intakes of empty calories result in fat gain and hence should be avoided by dozens of which lose fat. Some examples of foodstuffs with empty calorie content are carbonated drinks, jellies, ice cream, sweets, candy, margarine, white rice, white bread, butter, lard, alcohol based drinks, beer, wine and fatty unhealthy foods like hamburgers, pizza, hot dogs, fried chicken, and French fries.
Are all calories built the same?
The response is no; all calories usually are not built the same. It is a common myth in the fitness world that fat loss or fat gain is simply few how many calories have you ever consumed and how many have your burnt; i.e. a calorie is similar whether it is 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 low 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 nutrients and vitamins from the calories ingested by Group B is a lot above 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 a banana?
It was widely believed so far that calories are processed and metabolized in the same manner in your body. But scientific studies have shown otherwise; our body 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 offer a similar experience in their energy content but your body processes all these in different ways. This is because your body must spend different numbers of energy to process and metabolize the many nutrients and calories; more energy is spent to process proteins than carbohydrates and more energy to process carbohydrates than fat. Hence, 120 calories from a banana add fewer calories to your body than the usual 100 Cal pack.
Does your body digest calories exactly the same at different times from the day?
It was considered that the nothing to do with just how our body digests calories and hence it is possible to eat out at any time from the day and never have to worry. But legally to have has revealed that there exists indeed an inaccurate time and energy 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 your body in the way it processes and metabolizes calories. Though the digestive process from the body remains exactly the same, it's been noted that eating late into the evening frequently contributes to fat gain along with other bloating in comparison to those who had an early on dinner. But none on this has been confirmed completely and the question still remains debatable.
