Question 99 (1 point) John routinely consumes 7,000 calories per day in excess of his energy expenditure. How much body fat would John store per day as a result of this practice? a) 1//2 pound b) 2 pounds c) 11//2 pounds d) 1 pound

<p> To answer this question, you need to understand the idea of energy balance as it relates to consumption and expenditure of calories, and how excess calories can lead to the accumulation of body fat. Here's a simplified viewpoint: positive energy balance—that is, more calories consumed than burned—is the fundamental cause of weight gain. This is because when you consume more calories than your body needs for immediate use, those unused calories get stored away for future use, quickly as fat tissue.<br />The often-referenced number for the amount of calories in a pound of fat is 3500 calories - this means it would need an extra 3,500 calories (over and above your maintenance level) to gain a pound of fat. Therefore, if John is consuming 7,000 calories a day more than his body is using, he would accumulate two pounds (7,000 ÷ 3,500 = 2) of fat a day if that energy isn't burned someway, providing all other factors remain the same and this excess energy isn't somehow burned off by him through additional physical activity or exercise.</p>
