Jake Is Getting Ready for Spring Training and Is Sitting

question 69

Multiple Choice

Jake is getting ready for spring training and is sitting down to a dinner of half a chicken, a rib-eye steak, black beans, and 5 slices of bacon. He has been eating typical dinners like this for about a month and has since gained 3 kg while exercising only briefly. Why hasn't Jake seen an increase in his biceps or abs?

• A) Dietary protein alone does not contribute to muscle accretion.
• B) It takes at least 6 months to document changes in muscle accretion.
• C) The weight he has gained can be attributed to a substantial increase in otherprotein stores.
• D) Because muscle accretion only responds to very lean meat choices, he should eliminate the fatty bacon and steak from his diet to promote muscle gain.
