Answer #1

1-84 kg

2-BMI is 25.9

8- carbohydrate intake 6-10 gm / kg

Carbohydrate Needs
The USDA recommends that 45 to 65 percent of your total daily calories come from carbohydrates.
For example: To consume 60% of total daily calories from carbohydrate sources:
• A moderately active 18-year old male who requires 2800 calories a day would need to consume 1680 calories from carbohydrate sources.
• A moderately active 18-year old female who requires 2000 calories a day would need to consume 1200 calories from carbohydrate sources.
Fruits, vegetables, grains, and milk are carbohydrate sources.
