Empty calories reference the volume of energy contained in certain high-energy foods, who have low nutritional value. In such foodstuffs, the power mainly comes from the processed carbohydrates or fats and sometimes-even ethanol. Typically a clear calorie will contain the equivalent amount of energy as everyday calories but is poor in its nutritional benefit like lack of vitamins, minerals, amino acids, fiber and antioxidants. Intakes of empty calories bring about weight gain and therefore must 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 unhealthy food like hamburgers, pizza, hotdogs, fried chicken, and French fries.
Are all calories created equal?
The fact is no; all calories are not created equal. It is a common myth inside the fitness world that weight loss or weight gain is simply matter of how many calories maybe you have consumed and how many have your burnt; i.e. a calorie is the same be it obtained from proteins, fat or carbohydrates. But this is not the truth. For example; just consider two groups - Group A consumes 2000 calories from pizza, carbonated drinks, hotdogs and low while Group B consumes 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 nutritional value from the calories ingested by Group B is really a lot higher than Group, A so that it is different.
Does one's body process all calories the same way? For example; 100 Cal pack vs. 120 Cal from the banana?
It was widely believed until recently that every calories are processed and metabolized inside the same manner in your body. But scientific research shows otherwise; our body reacts very differently to calories according to its source and how 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 each one of these in a different way. This is because one's body has 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 much more energy to process carbohydrates than fat. Hence, 120 calories from the banana add fewer calories in your body compared to a 100 Cal pack.
Does one's body digest calories the same at different times from the day?
It was belief that the not even attempt to do with the way in which our body digests calories and therefore you are able to get your meals at any moment from the day without needing to worry. But a recent study has said that there is certainly indeed a wrong time to eat. Though you'll find conflicting reports, there is certainly enough and much more circumstantial evidence to prove that bad eating habits and wrong timings definitely affect one's body inside the way it processes and metabolizes calories. Though the digestive process from the body remains the same, it's been noted that eating late at night frequently brings about weight gain and other bloating when compared with individuals who had a young dinner. But none of this has been proven completely so the question still remains debatable.
