The term convection generally refers to the movement of fluids, meaning liquids and gases, but in the earth sciences, convection also can be used to describe processes that occur in the solid earth.

The recommended range is 45 â 65% of calories as carbohydrate. For example, if you eat 1600 calories per day, and 50% of those calories are carbohydrate, you would eat 200 grams per day. Athletes need to eat at the high end of the carbohydrate range, to fuel training and competition.
Men: 250 additional calories per day. For example, if you are a guy with a daily calorie maintenance level of 2000 calories, you should now eat about 2250 calories per day to build muscle. Whatever your maintenance level is, just be 250 or so calories above it each day. Women: 125 additional calories per day. For example, if you are a girl with a daily calorie maintenance level of 2000 calories, you should now eat about 2125 calories per day to build muscle. Whatever your maintenance level is, just be 125 or so calories above it each day.
