- 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.

- Basal 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_forwardThe long-term stability of weight is often considered a marker of energy balance. According to Hall et al., why does weight change in the short term not necessarily represent energy imbalance? Changes in body weight include changes in body water, which may be variable Rapid turnover of fat stores can lead to short term changes in body weight Variations in energy stored per unit of body weight exist All of the abovearrow_forwardDiscuss the relative effectiveness of dieting and exercise in losing weight noting that most athletic activities consume food energy at a rate of 400 to 500W while a single cup of yogurt can contain 1360KJ (325 kcal) specifically is it likely that exercise alone will be sufficient to lose weight? You may wish to consider that regular exercise may increase the metabolic rate, whereas protracted dieting may reduce itarrow_forward
