The role of protein?

[bike man]

1. There are any number of googleable sites that deal with exercise vs carb/prot/fat ratio.

I try to maintain approx 20 - 21 percent of my daily caloric intake as fat, about 30% as protein, and the rest carbohydrate. For the most part I am successful.

I am 70, was recently measured at 16% body fat (although at 195 lbs the BMI chart is not kind to me). I lift weights 5 days a week, eat about 1700 calories/day, and consume about 124 ounces of fluids (includes the water in various food products), no sodas or other sugar beverages. I use a computer food journal and enter every morsel that passes my lips.

This works for me. YMMV

edited again. using DietPower 4.4, just finished the journal for today

total calorie intake 1488

fat 30.7 g (19%)
prot 137 g (37%)
carb 166 g (44%)
117 oz fluid, which includes the fluids in the various food items as well as beverages.
