Answer 1

Fats have more calories than carbohydrates and proteins, with one gram of fat providing about nine calories, compared to four calories for a gram of carbohydrates or proteins.

Step-by-step explanation:

Fats are one of the six nutrients and can be found in animal products, nuts, and oils. They have more calories than carbohydrates and proteins. This is because fatty foods are calorie-dense, meaning that they contain more calories per unit mass compared to carbohydrates or proteins. For example, one gram of fat has approximately nine calories, whereas one gram of carbohydrates or proteins has about four calories each. This high energy content is why animals, including humans, may seek lipid-rich food.

Furthermore, fats, also known as lipids, play several vital roles in the body. They are used for building cell membranes, are high in brain and nerve cells, and help with the absorption of fat-soluble vitamins such as A, D, E, and K. Despite these benefits, an excess intake of fats can lead to the storage of extra energy in fat deposits, potentially resulting in weight gain and associated health risks.
