- Consider a 96 kg adult, who is overweight. Weight loss would improve their general health and wellbeing. If 35 % of the body mass of this 96 kg adult consists of TGs (in adipose tissue), what is the total available fuel reserve, in kJ and kcal, in the form of TGs? 2. This 96 kg adult decides to begin a starvation diet to lose weight. They aim to reduce their weight to 75 kg, which will be a weight loss of 21 kg. If the only source of nutrient energy for this 96 kg adult is the oxidation of fatty acids stored at TGs, how long (in days plus hours) will it take for this person to lose 21 kg of their body weight under starvation conditions? The daily energy expenditure for this 96 kg adult is 8700 kJ. This is equivalent to the recommended Australian average daily energy intake of 8700 kJ. 3. Calculate the weight loss in kg/day under such starvation conditions if the oxidation of fatty acids stored as TGs were the…arrow_forwardConsider the energy budgets for a human, an elephant, apenguin, a mouse, and a snake.

A. Most of the energy stored in the human body is in the form of fat, followed by protein. The body has only limited capacity for storage of carbohydrate. B.

- What is the meaning of the term "Calories" written on food packaging? By convention, one Calorie (C), with a capital C, that is used for food is equal to one kilocalorie. On your Activity Sheet, paste a label or cut-out portion from food packaging indicating the number of Calories. (If you have no packaging at home, you may invent and draw your own label.) Convert these Calories into kilocalories and calories.arrow_forwardAssume that you want to lose 20 lb of body fat in 60 days. Your present dietary intake is 3000 Cal/ day. What should your caloric intake be, in Cal/day, to achieve this goal, assuming no change in exercise habits?arrow_forwardOne food calorie = 1 X 103 calories = 1 kcal. A typical adult ingests about 2200 food calories per day. (A) show that an adult uses energy at about the same rate as a 100-W light bulb. {B) Calculate the total annual metabolic energy expenditure of the 6 X 109 people on the earth and compare it with the 4 X 1020 J per year energy used by the world economy. Assume all persons consume 2200 food calories per day, which is obviously incorrect.arrow_forward
- A 1-oz (28.3-g) serving of regular potato chips has 10 g of fat and 150 Calories, whereas 1 oz of the socalled fat-free chips fried in olestra has only 75 Calories. Consider a person who eats 1 oz of regular potato chips every day at lunch without gaining or losing any weight. Determine how much weight this person will lose in one year if he or she switches to fat-free chipsarrow_forwardDifferent lifestyles and careers can result in completely different energy requirements -even between two similarly sized people of the same sex. (a) Compare the energy requirements of an office worker and a landscaper who mows lawns with a push mower for 8 hours each day. Who has the higher energy requirement and why? [2] (b) What might happen over the course of one year if they each consume the same number of Calories daily? Explain why.arrow_forwardhGH is an important part of fat metabolism, muscle development, and bone growth. Synthetic hGH can be used to treat children and adults suffering from hGH deficiency. More recently, competitive athletes have began taking hGH in an attempt to improve athletic performance. The use of hGH for athletics is banned by many major sporting organizations. A recent study of 44 athletes who took daily injections of hGH over 20 days showed that, on average, the athletes gained 4.2 lbs of muscle, but the gain in muscle did not translate to increased athletic performance.Evaluate each statement regarding the use of hGH by competitive athletes to determine whether the statement is an example of an ethical, economical, societal, or environmental issue. Athletes who play professional sports should be encouraged to take synthetic hormones to improve performance because their job is to win. Athletes who took hGH did not improve their sport performance but did improve their appearance and marketability.…arrow_forward
- Caroline is a 39-year old high school English teacher who weighs 141 pounds and does not get a lot of exercise. Based on this information, each day Caroline should consume _____ grams of protein for each kilogram of body weight, meaning that she should consume approximately _____ grams of protein per day. (Hint: 1kg = 2.2lb) 0.8; 51 0.8; 113 1.0; 64 1.2; 53arrow_forwardBasal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) Calculate how many Calories you burn overall in a day.arrow_forwardAn individual with an energy expenditure of 30 L of O2/mile and an RER of 0.2 would have to run how many miles to consume 500 kcal?arrow_forward
