How Many Calories Should We Eat a Day(2)

Recommended daily calorie intakes vary across the world. According to the National Health Service (NHS), UK, the average male adult needs approximately 2,500 calories per day to keep his weight constant, while the average adult female needs 2,000. US authorities recommend 2,700 calories per day for men and 2,200 for women.
The NHS stresses that rather than precisely counting numbers (calories), people should focus more on eating a healthy and well balanced diet, being physically active, and roughly balancing how many calories are consumed with the numbers burnt off each day. If you eat your five portions of fruit and vegetable per day, you will probably live longer, Swedish researchers reported in the American Journal of Clinical Nutrition (July 2013 issue).
According to the United Nations' Food and Agriculture Organization (FAO), the average person's minimum calorie requirement per day globally is approximately 1,800 kilocalories (7,500 kJ).

Over the last twenty years, sugar has been added to a growing number of foods we consume. Unfortunately, food labels in the USA and Europe do not include details on how much added sugar there is . Dr Aseem Malhotra, a cardiologist, wrote in BMJ in June 2013 that "(it has become) almost impossible for consumers to determine the amount of added sugars in foods and beverages."
Timing could be as important as how many calories you eat
A big breakfast helps bring your weight down or keep it down - researchers from Tel Aviv University explained in the medical journal Obesity that a large breakfast - one containing approximately 700 calories - is ideal for losing weight and reducing your risk of diabetes, heart disease, and high cholesterol.
When we eat our food probably matters as much as what and how many calories we eat.h
