The correct answer is D. energy deficit.
An energy deficit occurs when you consume fewer calories than you burn on a given day. This means that you are burning more calories through physical activity and bodily functions than you are taking in through food and drink.
To understand this concept better, let's break it down step by step:
- 1. Calories: Calories are a unit of measurement for energy. When we consume food and drinks, our bodies break down the macronutrients (carbohydrates, proteins, and fats) and convert them into energy. This energy is used for various bodily functions like breathing, digestion, and physical activity.
- 2. Consuming fewer calories: When you consume fewer calories than your body needs, it creates an energy deficit. This deficit means that your body doesn't have enough energy from food to meet its needs.
- 3. Burning calories: On the other hand, when you burn calories, your body uses energy for activities like exercising, walking, and even sleeping. The more physical activity you do, the more calories you burn.
- 4. Energy deficit and weight loss: When you have an energy deficit, your body starts to use stored energy (such as fat) to make up for the lack of calories. This can result in weight loss over time.
So, in summary, an energy deficit occurs when you consume fewer calories than you burn on a given day. It is often associated with weight loss because your body taps into its stored energy to make up for the calorie shortfall.
