High fat foods are high in calories because fat has more calories per gram than the other nutrients. Instead of having 3 calories per gram like carbohydrates and protein, fat has 9 calories per gram. Basically this means that each molecule of fat contains more food energy than the other nutrients.

What type of molecule has the highest caloric value per gram?
Fats, also known as lipids, have the highest caloric value per gram, providing approximately 9 calories per gram. This is significantly higher than carbohydrates and proteins, which both yield about 4 calories per gram. The dense energy content in fats makes them a key energy source for the body, especially during prolonged physical activity or periods of fasting.
Why does the caloric value vary among biological molecules?
The caloric value of biological molecules varies due to differences in their chemical structures and the types of bonds they contain. Carbohydrates, proteins, and fats have distinct molecular compositions, with fats typically providing more energy per gram due to their higher hydrogen-to-oxygen ratio and more extensive carbon chains. Additionally, the energy released during metabolism depends on the complexity of the molecule and the energy required for its breakdown. Consequently, fats yield more calories than carbohydrates or proteins when oxidized for energy.
Which nutrient has the greatest caloric density?
Fats (lipids) have the greatest calorific density, whether they are oils or animal fats.

What is the caloric value of lipids?
Lipids do indeed have a high caloric value.
What is the caloric value of diesel oil?
The higher calorific value of diesel oil is 44,800 kj/kg and 19,300 btu/lb. The lower calorific value of diesel oil is 43,400 kj/kg.
What is the RDA for trans fats?
Trans fats are to be avoided for proper dietary measures. The RDA (Recommended Daily Allowance) for trans fats is less than 1 percent of the caloric daily intake
What is caloric value of carbohidrate?
7kcal/g
Minerals have no caloric value and thus do not contribute as an energy resource but they are important in regulating various bodily functions?
Minerals do not have a caloric value so the answer is true.
What are estimated average requirements for fats?
Estimated average requirements for fats typically suggest that dietary fats should comprise about 20-35% of total daily caloric intake. For adults, this translates to around 44 to 78 grams of fat per day, depending on individual caloric needs. It is recommended to prioritize unsaturated fats, such as those found in fish, nuts, and olive oil, while limiting saturated and trans fats for better health outcomes.
