Question

You and a group of friends are spending your vacation hiking through the mountains. It is cold in the mountains. You will be expending a lot of energy while hiking and you will need plenty of energy to help keep you warm.You should pack foods high in ________ to provide the most energy or kilocalories per gram of food.

Answer 1

You must pack food that has high concentrations of fat and protein. Food like granola bars and canned meat are a good source of energy and heat. This is because the body breaks this food down easily converting it into usable energy. Though some people would suggest that you pack food that are high in carbohydrates, fats and proteins are long-term sources of energy that you would need for your hiking trip. 

Answer 2

Answer: The correct answer is fat.

Explanation:

Though, our body uses carbohydrates as the primary source of energy but fats provide more energy and heat as compared to the carbs.

Each gram of fat provides 9 Kcal of energy as compared to 4 Kcal of energy produced by carbs or proteins.

In addition, fats or lipids are long term energy reserves of the body. So, they are able to provide you energy during long duration of physical activity such as hiking.

Fats also help in making an insulating layer around the body which decreases the surface lost of heat and thus, help in keeping you warm.
