How do you know what diet is right for you? You can find it out through trials and errors and, finally, if you are lucky, you will find the diet that suits you well. Or you can approach the task more scientifically. Here I will try to help you to find the energy level your body needs. After we know your requirements we will be in a position to find the proper diet for you.

People are divided into 5 groups depending on the type of job they are doing. Here I will tell you about 4 groups. We will not consider 5th group, as it mostly depend on jobs with a very high level of physical activity.

 

1st group: very light physical activity

 

This group consists mostly of office workers; managers, engineers, teachers, secretaries, scientists, authors etc. People in this group spend most of their day at their desks and get very little physical activity.

 

2nd group: light physical activity

This group would include a large part of service workers; salesmen/women, shop assistants, car drivers, agronomists, veterinaries, nurses, hospital attendants etc. People in this group spend a great part of the day on their feet but are not engaged in physical job.

 

3rd group: moderate physical activity

Members of this group include: machine operators, metalworkers, textile workers, bus drivers and truck drivers, foodservice workers, public works, transportation workers etc. This group spends some part of the day in moderate to heavy physical activities.

 

4th group: high physical activity

This group include: builders, agricultural workers, metallurgists, foundry workers, oil and gas industry workers, woodworkers etc. Members of this group spend most of the day engaged in heavy physical activities.

 Every group is divided by age categories. You can estimate your body’s energy requirements, but you should remember, it’s only an approximate value.
