What are the different types of calories?
There are different classifications of foods in terms of calories. This includes high-calorie foods, low-calorie foods, and empty calories. Consistent with their naming, high-calorie foods are foods that are calorically dense, meaning that there are a high number of calories relative to serving size, while low-calorie foods have fewer calories relative to serving size. Foods such as fat, oils, fried foods, and sugary foods are examples of high-calorie foods. Being a high-calorie food does not inherently mean that the food is unhealthy however – avocados, quinoa, nuts, and whole grains are all high-calorie foods that are considered healthful in moderation. Low-calorie foods include vegetables and certain fruits, among other things, while empty calories, such as those in added sugars and solid fats, are calories that contain few to no nutrients. Studies have shown that there is a measurable difference between consuming 500 calories of carrots compared to 500 calories of popcorn. As previously mentioned, this in part can be attributed to differences in how the foods are consumed and processed. Carrots require far more chewing and can result in more calories burned during digestion. Again, the mechanism for these differences is not fully defined, but simply note that for weight loss purposes, the general formula of calories in minus calories out determining weight gain or loss does hold, but that the number of calories on a nutrition label is not necessarily indicative of how many calories the body actually retains. While there is no clear-cut or ideal amount of macronutrient proportions a person should consume to maintain a healthy diet or lose weight, eating a "healthy" diet replete with a variety of unprocessed foods such as vegetables, fruits, and lean meats is correlated with being healthier, and is more likely to result in sustainable weight loss. Also, remember that calories from drinks comprise an estimated 21% of a typical person's diet. Many of these calories fall under the category of empty calories. While sodas are an obvious culprit, drinks such as juices and even milk have large amounts of sugar and should be consumed in moderation to avoid negating their nutritional benefits. Ideally, a person should drink water, tea, and coffee without adding sugar in order to reduce calories gained from drinks.

How to reduce calories in a diet?
We can reduce the number of calories by simply eating less mass, or we can change our dietary macronutrient balance in order to consume less fats (high energy density) and more carbs and proteins. Since there is a sort of an upper limit to the amount of proteins we can eat in choosing the second option we often reduce fats and increase carbohydrates. There are low-carb diets such as Keto which shift the balance the other way. Evidence [5] points to this leading to losing less fats when dieting, even though one loses more weight overall, which is not good since fats are what is hard to get rid of and which is, at the same time, most beneficial to get rid of, so it appears that reducing fat intake and thus the overall caloric intake is the preferred way, in general.
