Body Mass Index
This is also called the Quetelet index. It is a form of measurement that is used for calculating the fat content in the body of organisms. Weight gain is directly related to an increase in fat content in the body. It is not a percentage weight but just a number (Grosvenor and Smolin, 2010). In addition, the body mass index can be used to explain the thinness or thickness of a person. This measurement can give a nutritionist a green light on how to advise a patient on weight issues and how to go about managing the issues. This applies to both weighty and nonweighty people.
BMI =Mass (Ib/) x 703/Height (In)
=205×703/(69)2=30.4
Daily Energy Requirements
Daily calories burned can only be calculated accurately using a physiological testing (James, 1990). Reggression analysis would provide a result as shown below:
(13.75 x Wt) + (5 x Ht) – (6.76 x Age) + 66 = kcal/day
= (13.75 x 205×703) + (5 x1.75×1.75)-(6.76 x38) +66
Daily energy requirements =1958 kcal/day or 8192kJ/day
Energy Balance
For Jack to maintain stable body weight, he needs to achieve energy. To get this balance, he needs to equalize the energy expended and energy ingested by his body. Weight gain or obesity results from reduced physical activity with increased intake of energy. Another reason could be occasional bouts of positive energy in the body. To gain this balance, it is important to have a check on the macronutrient intake rate.
The body oxidizes macronutrients to achieve a homeostatic nature in normal individuals. However, the priority for oxidation is for the macronutrients (Wardlaw and Smith, 2009). Carbohydrates are easily oxidated followed by proteins and lastly fats. The oxidative priority for fat is low, therefore taking a fat-rich food will mean that the balance ratio is compromised. This would lead to imbalance hence weight gain.
Jack will therefore need to increase his physical activity until it reaches the level of energy intake. This state is termed a steady-state or balanced state. A man weighing about 166Ibs should be 5’10’’ tall. If the guy weighs 106 pounds for 5 feet then he should add 6 pounds for each inch he adds.
Report and Recommendations
At the moment Jack is overweight. He has a condition that is not healthy to live with. To be overweight means that the body has a lot of stored fats. This can result in heart conditions that might result in a heart attack. In addition, it is associated with diabetes Mellitus which is type-two diabetes. Other conditions include osteoarthritis, Carcinoma disease, and respiratory problems. Weight loss options would be the best decision for Jack to deal with his condition.
Jack needs to do a lot of exercise and eat the right type of food (Wardlaw and Smith, 2009). At times it is advisable to lose weight by control of diet then afterward one can do exercise normally. Moreover, Jack should be able to balance his energy intake and expenditure habits. He should neither have positive energy nor negative energy but rather a steady state of energy.
Exercise is good for everyone. But, overweight people should do exercise to work on their fats. Swimming is one good example of exercise (Wardlaw and Smith, 2009). Walking and other cardiovascular exercises are also good for Jack. Therefore, he should make it a routine to visit the gym more often. Discipline is one important virtue when dealing with weight loss for better and healthy living. Moreover, having a positive attitude can also help out a great deal during exercise procedures for healthy living.
