Calories are the energy in food that helps your body do everything from sleep to run. The calories in food can come from carbs, fats, and proteins. Your body can use calories to fuel activities or store them for later use as body fat.

Monounsaturated fats are healthy fats found in olive oil, avocados, and some nuts. In fact, some evidence suggests that monounsaturated fats have positive health effects, including weight loss, a reduced risk of heart disease, and reduced inflammation.

Omega-6 acid is the name of a type of unsaturated and polyunsaturated fat. The human body is unable to synthesize this essential fat and needs to be supplemented from external foods containing Omega-6 acid.
