WEIGHT MANAGEMENT Dietary Guidelines Recommendation: A calorie is the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. Calories in food provide energy in the form of heat so that our bodies can function. Our bodies store and \"burn\" calories as fuel. To maintain body weight in a healthy range, balance calories from foods and beverages with calories expended. To gain weight, consume more calories than you expend and to lose weight, expend more calories than you consume. The daily recommended caloric intake for the average American is 2,000 calories per day. The number of calories needed can vary per individual based on sex, body size, activity levels, metabolism, etc. 1. 3,500 calories equal 1 pound (lb). For example, an individual wanting to gain weight could consume an extra 500 calories/day for 7 days and gain 1 pound in a week. To lose weight, an individual could either consume less calories than needed and/or expend more calories through exercise. Please answer the following questions below and show full work:

A) Tom does not like to exercise. Tom weighs 300 pounds and has been instructed to lose 20 lbs by his doctor. If Tom cuts out 500 calories from his diet everyday until he reaches his goal weight of 280 Ibs, how many weeks until he achieves his goal? (3 pts) I

B) Jack weighs 130 lbs and wants to gain weight. He has been working out for 3 days/week for the past 6 months. He works out for one hour and burns 1,000 calories during his workout. He has calculated that if he consumes 1,500 calories per day, his weight will stay the same so he eats 2,500 calories every day to make sure he will gain weight. How many net calories is Jack consuming per week? At this rate, about how many weeks will it take him to reach 140 lbs?
