Regarding Calories?

Question

Hi

when we see the ingrdients of products. It says that the energy provided by them is x(Kcal). Does Kcal means Kilo Calories? If not what do they exactly mean? How should we interpret it for calculating our daily consumption?

Answer 1

You or your parents may not be used to the idea of measuring energy in Joules. An alternative unit that is used is Calories. You see these on just about every food packet. One calorie is the same amount of energy as 4.2 Joules.

The daily use of energy is:
Baby --- 1000 kilo calories (1 Million calories)
Child --- 2000 kilo calories (2 Million calories)
Girl/Boy (i.e. you) --- 2,500-3000 kilo calories (3 Million calories)
Woman --- 2200 kilo calories (2.2 Million calories)
Man --- 3000 kilo calories (3 Million calories)
Manuel labourer --- 4000 kilo calories (4 Million calories)
Different foods contain different amounts of chemical energy.

For example, a 24 gram bar of chocolate contains the same amount of energy as 1kg bag of tomatoes..

Answer 2

In nutrition, a unit called the kilocalorie, also known as the diet calorie, is frequently mentioned. This unit is equivalent to 1000 cal, and is the amount of heat energy required to raise or lower one kilogram (1 kg) of pure liquid water by 1º C or 1º K. When the label on a package of food says that a serving contains 200 calories, it means that the sample would yield 200 kcal (not 200 cal) of heat energy if subjected to complete combustion. Kilocalories are used (and misused) to express the amount of food consumed in a serving, a meal, or a day. It has been said that a surplus of 7700 kcal of food intake will result in a mass gain of 1 kg, or that a surplus of 3500 kcal of food intake will produce a weight gain of one pound (1 lb), which represents 0.454 kg in the gravitational field of the earth at the surface. Some nutritionists and physicians, however, point out that this is a simplistic view, and can lead to abusive dieting and the neglect of physical activity as a factor in the maintenance of ideal weight and overall health.

Answer 3

No do no longer eat purely 2 hundred energy/day on your attempt to drop some pounds. i think of what you're doing is misinterpreting what you have learn wanting to lessen calorie utilization by way of 3500 energy/week so as to lose one million pound/week. and you will shrink energy by way of the two reducing nutrition intake or increasing activity ranges or a mixture of the two. in case you burn 3 hundred energy/day and shrink your caloric intake by way of 2 hundred energy/day which may be an entire alleviation of 500 energy/day. in case you probably did that 7 days/week you may have decreased the 3500 energy for that week which might equivalent the single million pound alleviation on your weight. so as which may be eating a weight loss plan of 2000 energy minus 2 hundred energy which may be 1800 energy/day. So your objective daily energy could be 1800 energy/day and you'd be determining burning 3 hundred energy/day. There are different factors touching directly to weight alleviation yet this easy answer works as a enormously solid education.
