Bi Sci 001 Monday March 15, 1999 Announcements: Review Session tonight at 110 Wartick Lab, from 6:30-7:30 Lecture notes: How much protein do we really need? The RDA is .8 gm. of protein per kilogram (2.21 lb.) of body weight for non- athletes. Estimates: * for athletes add .4 g/k to get 1.2 g/k/day. (50% more) * for a 150 lb. Athlete (68 kg) the means approx. 82 gm. of protein per day. * 1/2 a chicken breast is 30 gm. of protein * 1/4 hamburger is 25 gm. of protein * 1 cup of milk is 8 gm. of protein. *** Rule of thumb: 1 oz. of meat is 7 gm. of pure protein.*** Energy balance "Energy in" should equal "Energy out" Too much in = weight gain Too much out = weight loss There are 3,500 kcal worth of energy in one pound of fat. To lose one pound of fat you must: a) take in 3,500 fewer kcal b) use up an excess of 3,500 kcal c) a combination of both It is better to combine calories restriction with exercise the to use calorie restriction alone.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
