Math is everywhere in our life. Math is very important for us. Also math uses when you calculate calories, weight etc. So I focus on math in dietary science. Let's start learning.
What are calories?
What are calories?
Calories are a measure of energy, normally used to measure the energy content of foods and beverages. In science, it's defined as the amount of energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius. Many people think weight lose is simply about cutting calories. They believe that to lose weight, you must reduce calories,to gain weight, you must add calories. I will say it is true, however it is not that easy.
Counting calories
Counting calories
Energy difference at the end of the day = Energy in (as food) – energy used (in exercise or just in living)
This formula is easiest and basic of counting calories.
All foods contain calories. Healthy foods have lower caloric values than foods that are contain more fat and sugar. The body burns calories and uses them as fuel to power its everyday activities. If one consumes more calories than they burn, he or she will gain weight. calories are constantly being burned in the body, even when a person is asleep.
How Many Calories Should You Eat on Average?
How Many Calories Should You Eat on Average?
Counting calories are important. Also it is important to know how much you have eaten a day.
Average woman needs to eat about 2000 calories per day to maintain, and 1500 calories to lose one pound of weight per week. An average man needs 2500 calories to maintain, and 2000 to lose one pound of weight per week.
We can know from this, we eat more than 2000 calories or 2500 calories, we will gain weight. Other hand, you calculate calories and if it does not exceed the average, you will not gain weight.
However, this depends on numerous factors. These include age, height, current weight, activity levels, metabolic health and several others.
How Math Relates To Food Science
How Math Relates To Food Science
The science of food is primarily based on math, as it revolves around numerical values. For example quantity measurements, rates at which foods burns, and ratios of liquids to solids in food.
Exercise time required to lose weight? (Example)
Exercise time required to lose weight? (Example)
- I compare the exercise required for 60 kg people to lose 1 kg body fat.
1, Running (weight (kg)×distance(km)
⇒1Kg Body fat＝7200kcal
⇒7200（kcal)÷60（Kg）＝120(km)
⇒120（Km）÷10（Km/ho）＝12(hours)
2,swimming
⇒The calorie consumed by 60 kg person for 1 hour swimming: about 500kcal
⇒7200（Kcal）÷500（Kcal/hours）＝14.4 (hours)
