1. BMI= (weight in pounds * 703 ) = (220*703)/69² = 32.5 ———————————— height in inches² According toAlfred’s body mass index, (BMI)Alfred is in the obesity category and therefore he is not in the appropriate BMI range, as his BMI should be between 18.5-24.9 category. [2] The general recommendations I would make are to increase the amount of exercise he does as it mentioned that he isn’t very active.Another recommendation I would make would be to change up his diet in order to reduce his calorie, and fat intake such as saturated fats, and cholesterol. I would also recommend more physical activity daily in order to bring down his weight and maintain a healthy lifestyle. 2. EER (men) = [662 - (9.53*Age)] + PA*[(15.91*wt) + (5.39.6*ht)] = [662 - (9.53*19)] + 1.11*[(15.91*99.79) + (5.39.6*1.7526)] = [662 - (181.07)] + 1.11*[1587.66 + 945.70] = [480.93] + 1.11*[2533.36] = [480.93 + 2812.0296] = 3292.96 It was mentioned before thatAlfred’s daily physical activity is very low, meaning he is not very active. According to the Canada’s food guide, males between the ages of 19 to 30 who are classified in the low physical activity category should have the estimated energy requirement of 2700.[2]After using the estimated energy requirement formula for males, it was calculated thatAlfred’s EER is 3292.96. This number is above the required amount which is not seen as a positive thing as it can lead to weight gain. Since the calculated number is significantly higher than the recommended number it is proven whyAlfred’s body mass index is in the obesity category, and his low physical activity rate is a giant contributor, along with an unhealthy diet. The EER shows energy accuracy by using one’s height, weight, and physical activity. SinceAlfred’s physical activity is extremely low compared to his recommend a better diet without unhealthy fats, and a lower calorie intake. Secondly, I would highly recommend increasing his physical activity rate as it is extremely low and will bring his EER number down to more of an appropriate and suitable amount. 3. carbohydrates: 479.27 x 4 = 1917.08/ 4708.50 = 0.407 x 100% = 40.7% fat: 245.31 x 9 = 2207.79/4708.50 = 0.469 x 100% = 46.9% proteins: 150.43 x 4 = 601.72/4708.50 = 0.128 x 100% = 12.8% By looking at these calculations, it is evident that according to the current DRIAcceptable Macronutrient Distribution Ranges (AMDRs),Alfred is not meeting the requirements for carbohydrates because a suitable range would be between 45-65%, and fat because a suitable range adjustments with his diet for example replacing white bed with whole wheat, and adding more grains into his diet. His best bet is to add more whole wheat into his diet since it is a healthy source of carbohydrates and will make an equal balance of macronutrients in his body. Although he may be low on carbohydrates according to theAMDRs, he is extremely high on fat. 46.9% of his total calorie intake is fat, which i
