joja [24]

He complains of a poor appetite and being overly weak and tired. He also complains of cracks at the corners of his mount and a chronic sore throat which concerns him, given his cancer history. His usual diet is fairly consistent. He states that he rarely eats breakfast because he starts work at 6 a.m. He eats two deli meat sandwiches, "usually pastrami or salami," and a soda at 10 a.m., and may eat a candy bar in the afternoon when he gets off work. He often prepares frozen dinners or pizza at home in the evening and routinely drinks "about 4 or 5 beers" before going to bed. Occasionally he will cook a roast and mashed potatoes. He occasionally will have milk with cereal but rarely eats vegetables or fruit. He would like to know which vitamin supplement will give him energy.1.What is Samuel’s Ideal Body Weight?

50 + (0.91 × [height in centimeters − 152.4])

convert his height in inches to centimeters

67inches=170.18

50+(0.91*(170.18-152.4)

66.1798kg

What is his current percentage of ideal body weight?

61.2/66.178*100%

92.47%
