7500 in 1 kg of fat.
The difference between kcal and cal is 1000 cal = 1 kcal. However, we usually count food calories with kcal, and use kcal and cal interchangeably. Therefore, 9 kcal [Food Calories] = 9 cal. So, to the point: If there are 9 kcal in 1 g of fat, there are 9000 kcal in 1 kg of fat (1 kg = 1000 g).
9 kcal/g
1Kg fat about 7000kcal. NO ,IT IS NOT. 1 g OF FAT HAS 9 kcal /g. it is obvious that 1000g (1 kg ) of fat => 9000kcal!
Fat = 9 kcal 2,200 kcal x 0.30 kcal = 660 kcal 660 / 9 kcal = 73.33 g = 73 g of fat per day
Atlantic herring (raw): - 100 g has 158 kcal - 1 fillet (184 g) has 291 kcal Pacific herring (raw): - 100 g has 195 kcal - 1 fillet (184 g) has 359 kcal.
Simply - your recommended daily caloric intake consists of three types of so called macronutrients: Carbohydrates, found in bread, rice, paste, ... - at 4 kcal/g Protein, found in fish, beef, poultry, eggs - at 4 kcal/g Fats, found in Oil, Meat, butter - at 9 kcal/g so if your recommended intake ist 2000 kcal/day and 50g of fats you could eat like this: 50 g fats * 9 = 450 kcal 150 g protein * 4 = 600 kcal 250 g carbs *4 = 1000 kcal ------------------------------------ approx. 2000kcal of course if you eat less protein and more fat (typical western diet) you could have this: 100 g fats * 9 = 900 kcal 50 g protein * 4 = 200 kcal 200 g carbs *4 = 800 kcal ------------------------------------ approx. 1900kcal So you BELOW recommend kcal but ABOVE recommend fat intake. Hope this helps.
Consuming 1g of fat yields about 9 kcal/g and can produce around 38 ATP molecules. Consuming 1g of carbohydrate provides about 4 kcal/g and can produce around 36-38 ATP molecules. So, in this case, consuming 1g of fat would yield slightly more ATP compared to 1g of carbohydrate.
30g fat X 9kcal/g = 270 kcal divide the 270kcal by the total 1400 kcal = .19 .19 X 100 = 19%
Assuming 4 kcal/g for carb and protein and 9 kcal/g for fats, the total would be (15 x 9) + (25 x 4) + (20 x 4) = 315 kcal.
When we consume food, we get macronutrtients. These include carbohydrates, fats and proteins, the amount depneds on what food/foods are consumed. In terms of energy, fats provide 9 kcal/g, carbs 4 kcal/g and proteins 7 kcal/g. Therefore the most energy dense nutrient is fat and so on.
1 kcal equal 1 000 calories or 4,184 joules. 1 calorie is equal to the heat needed to increase the temperature of 1 g water with 1 0C.
