A Calorie is not a unit of weight, it is a unit of energy used in nutrition. Nutritional Calories are called kilocalories by physical scientists, to distinguish them from the lowercased physical calorie when speaking. A calorie is the minimum amount of energy it takes to raise 1 gram of water by 1 degree Centigrade. A nutritional Calorie is 1000 times larger than a physical calorie. When people outside of science talk about 'calories', they usually mean nutritional Calories.Einstein's Theory of Relativity implies that a substance heated by one Calorie will increase in mass by about 0.000000000000046 grams. In that sense, a Calorie does have an exact weight. However, that increase is negligible for the purposes of nutrition and weight management because Calories are stored in chemical compounds weighing much more than a Calorie.The weight of substance that your body can convert into one Calorie depends on the substance and the chemical reactions it will undergo. A representative reaction is burning table sugar, which is similar to cellular respiration in energy yield. In this reaction, it takes about .372 grams of sugar to yield 1 Calorie of heat. The lipid molecules in fat cells have a considerably higher energy density, and will therefore weigh much less than .372 grams per calorie stored.
Alcoholic beverages are high in calories, if you drink those it will be hard for you to stay within the allowed calorie budget required to lose weight. But sure, as long as it fits in your calorie budget you can have pretty much whatever and still lose weight.
Nutrient Density
IT is the same process.
1.5 gms of protein = 6 calorie 1 gm of fat = 9 calorie 2.5 gm of carbs = 12 Total calorie in one disk = 27 calorie (approx)
