NHS report unveils crucial factors and steps taken to help determine the number of calories people to take on a daily basis in order to balance diet, weight and maintain healthy living
On average, people in the UK are taller than those in USA, but according to NHS report both in the United Kingdom and the United States, the minimum number of calories recommended on a daily basis have unusual variation. In the UK, NHS recommends the average male and female to take up to 2,500 and 2000 calories respectively but in the US, authorities have sought men and women to maintain at least 2,700 and 2,200 calories.
Balancing diet, weight loss, fitness for healthy living and weight management is based on several factors such as age, body size, height of an individual, gender as well as overall way of life. For instance, a 22 year old male at a height of 6 feet would need more calories than a 70 year old woman at a height of 5 feet.
The prevalent rate of obese and overweight people in the United States is higher than those in the United Kingdom. NHS emphasizes the benefits of physical fitness and maintaining a healthy balanced diet instead of on daily calorie count. NHS also stressed the need to balance the number of calories consumed to the numbers burned on a daily basis.
UN’s Food and Agriculture Organization (FAO), records that the minimum numbers of calories to be taken each day by an average person worldwide are about 1,800 kilocalories. The biggest question, however, is linked to calories and kilocalories. What is the difference between the two? On scientific level, 1 kilocalorie is equivalent to 1000 calories, but these days, both terminologies have been used to refer to the same meaning.
In the past, calorie consumption was limited because people relied mostly on non-processed foods but manufacturing of processed foods has led to higher calorie intake. For instance, a normal cheeseburger in the USA about 20 years ago had about half the number of calories in the same cheeseburger today.
Calories mismanaged can negatively affect people’s lives. Calories are needed for survival and the body needs energy to function properly. The brain needs about 20% of energy to function while the remaining percentage is consumed by the rest of the body.
Harris-Benedict Principle popularly known as Harris-Benedict equation has been used to determine the basal metabolic rate (BMR). This methodology is applied when an individual intends to determine the required calorie intake on a daily basis. Balancing diet, weight loss, fitness would lead to reasonable body weight according to results indicated during BMR arithmetic. Verified reports have showcased that muscular people need more calories even at the resting stage than non-muscular people.
Age, gender, bone density, height as well as muscle fat are all factors considered when calculating the number of calories to consume each day.
Although BMI is taken as a considerable way to calculate weight, it is disregarded by some experts since it doesn’t reflect on muscle fat. The most cherished weight measuring technique is the waist-hip ratio although it also omits muscle fat ratio. Dr. Margaret Ashwell, an ex-science director of the British Nutrition Foundation and her team during the 19th Congress on Obesity in Lyon, France, on May 12th 2012 presented a new and easy method that calculates the ideal body weight. This technique is known as the waist-to-height ratio. Diet, weight loss, fitness were subjects addressed but the doctor pointed out that keeping the waist circumference to less than half the height could promote improved life expectancy.
