The value of currency is that it renders items as different as a banana or a TV all down to the same measurable units. But are calories really an effective “currency” for measuring weight loss? Dr. Jason Fung joined THINK to make the case against calories.

Calories are a measure of energy and are commonly used to describe the energy content of foods. Watch out to know the amount of calorie a person needs daily.

Video Transcription: Hello folks,
Today we are going to discuss about calories and the amount of it, a person needs daily for a healthy living.

Calories are a measure of energy and are commonly used to describe the energy content of foods. The number of calories the body consumes in a day is different for every person. 2,000 calories is a rough average of what people eat in a day.

Counting calories may help you lose weight, but focusing on the sources of calories like carbohydrates and proteins that are obtained from foods such as whole-grain, fish and poultry can bring better overall nutrition.

There are three main factors involved in calculating how many calories your body needs per day
BMR known as basal metabolic rate, is the amount of energy your body needs to function at rest. When compared, men have a higher BMR than women.

The second factor is physical activity, includes everything from walking, lifting, and just moving around burns calories, but the number of calories you burn in any given activity depends on your body weight.

The thermic effect of food is the final addition to the number of calories your body burns. This is the amount of energy your body uses to digest the food you eat.

To calculate the number of calories you expend in this process, multiply the total number of calories you eat in a day by 0.10, or 10 percent and you will get the results.

If you’re wondering how many calories to eat every day to maintain an ideal weight – that’s a loaded question. You know you probably shouldn’t hit that all-you-can-eat buffet with the gusto of an Ironman competitor, but you aren’t sure how many calories you can safely consume without gaining that flab on your stomach.

To make this simple question even more confusing, it isn’t just the number of calories we consume that keeps us looking great and feeling good, but the kind of calories we consume. First, though, let’s look at a general caloric guideline for both men and women.

Generally speaking, for individuals who aren’t training to swim across the English Channel or climb Mt. Everest, they can count on eating between 2000 and 2500 calories a day to maintain their weight. For women, it’s the smaller number, and men can usually stand to consume a little more due to their higher muscle mass. This causes them to burn calories at a faster rate. Anyone who increases their muscle mass; however, will burn calories faster, but there are other factors in the equation such as:

– Your natural metabolic rate – the millions of chemical interactions in your body that determine how fast your heart beats, you breathe, you burn fat, etc. Most of your calories are burned every day when you are at rest. This is called your basal metabolic rate. (BMR)
– Your age – As we get older we burn calories more slowly
– Hormonal factors – conditions like hyperthyroidism or hypothyroidism can cause you to burn calories too fast or too slow
– The weather where you live – People who live in very cold or very hot climates will burn more calories to keep their bodies at a comfortable temperature
– Drugs you take – many drugs can interfere with the body’s metabolism, causing it to slow down or speed up
– Your level of physical activity – though most of our calories are burned when we are doing nothing, regular exercise tends to increase our BMR
– Diet – the absence of certain important vitamins and minerals can either boost your metabolism or hinder it. If you don’t eat enough iodine found in leafy green vegetables, for instance, this can affect your thyroid gland and cause you to become obese

To burn a pound of fat or to gain one, you will typically need to either cut 1500 calories from your diet or add them. Depending on the factors, and your goal to either lose weight or gain it, you can decide if you can hit that all-you-can-eat buffet. Just mind your reach if you’re standing behind the Olympic Swimmer Michael Phelps. He’s rumored to eat 12,000 calories a day!
