1. Основной обмен - затраты энергии для поддержания жизнедеятельности организма в состоянии покоя. Общий обмен - это сколько человек фактически тратит энергии за единицу времени. 
2. Нормы питания рассчитываются исходя из возраста, пола, трудовой деятельности (физических нагрузок), веса, состояния здоровья. Продукты рациона подбираются в зависимости от состояния здоровья (могут быть при различных заболеваниях назначены специальные диеты N1-15), общее правило в соотношении углеводов, белков и жиров - 4:1:1.
3. Последний приём пищи должен быть за 2-3 часа до сна (чтобы не нагружать организм пищеварением, а дать отдохнуть). Взрослым рекомендовано есть не меньше трех раз  в сутки, детям - не меньше четырёх. По распределению - 30% завтрак, 40% - обед, 10% полдник, 20% ужин.

Task. Read the article about London police.

The History of the London Police

In 1700 London had no policemen at all. A few men protected the city streets at night.
Many people were poor and there were so many thieves who stole money in the streets that people stayed in their homes as much as possible.
In 1750, Henry Fielding started to pay a group of people to stop thieves. They were like policemen and were called ‘Bow Street Runners’ because they worked near Bow Street.
Fifty years later, there were 120 Bow Street Runners, but London had become very big and needed more policemen. In 1829, the first London Police Force was started with 3000 officers. Most of the men worked on foot, but a few rode horses.
Today, London police are quite well paid and for the few police officers who still ride horses, the pay is even better than for the others.
