It really depends on what you are eating. All foods have different calorie counts. If you're dieting, pick yourself up a calorie count book at a book store. It'll help.
In general, 45% - 65% of your daily calories should come from carbohydrates.Example:If you eat 2000 calories a day, 900-1300 calories (225-325 grams) of carbohydrates are recommended.
To calculate the calories from fat, multiply the grams of fat by 9, since each gram of fat provides 9 calories. In this case, 10 grams of fat would yield 90 calories from fat (10 grams x 9 calories/gram).
To determine how many grams should come from carbohydrates in a 3000-calorie diet, you first need to decide the percentage of total calories that will come from carbohydrates. Typically, carbohydrates should make up about 45-65% of total calories. If we take 50% as an example, then 1500 calories would come from carbohydrates. Since there are 4 calories per gram of carbohydrates, you would need approximately 375 grams of carbohydrates (1500 calories ÷ 4 calories/gram).
calories com from 12 grams of fat is 118 cal.

There are 9 calories per gram of fat. So 20 grams of fat would be 180 (9 x 20) calories from fat... or 45% of the calories are from fat.
Every gram of fat has 9 calories. so 4 grams is 36 calories.
9 calories. So if something has 5 grams of fat, 45 calories come from fat.
7.5 grams 2000 (total daily allotted calorie intake) * 0.35 (35% of energy recommended to come from fat) = 700 total 80 grams @ 8 calories a gram = 640 total calories 700 - 640 = 60 calories remaining from fat 60 / 8 (calories per gram) = 7.5
To find the percentage of fat calories in the slice of apple pie, first calculate the calories from fat. Since fat has 9 calories per gram, 10 grams of fat would contribute 90 calories (10 grams x 9 calories/gram). Then, divide the calories from fat (90) by the total calories (180) and multiply by 100 to get the percentage. Thus, (90 / 180) x 100 = 50%. Therefore, 50% of the calories in the slice of apple pie come from fat.
One gram of carbohydrate contains approximately 4 calories. If the cereal contains 30 grams of carbohydrate, this would mean that 120 calories come from carbohydrates. 120 calories is 50% of 240; therefore, carbohydrates comprise of 50% of the total calories for your cereal.
