An impressive research study was completed by Washington University on three million people for over a decade. The study was looking at how exercise and diet affects obesity. Such research studies have large numbers; lengthy time frames and cannot be attempted many times or doubted. This research proved that most of the people who increased their physical activity in that decade had positively affected mortality, diabetes and cardiovascular diseases. However, rates of obesity remained unchanged.
The conclusion was that the key to reverse obesity is in a controlled diet with a combination of exercise. Increasing physical activity is not enough. Other studies conducted in Australia observed the same results. The reason is not that people are becoming gluttonous, but because of the environment changing and the uncontrollable food industry.
Food characteristics have changed. Food is now served in larger portions, contains lots of calories and is so processed that it is causing many chronic diseases.
At this point, mathematics can help us understand WHY WE DON’T LOSE WEIGHT BY INCREASING OUR PHYSICAL ACTIVITY ONLY. To explain, do we understand that with one hamburger we consume about 600-800 calories and to burn those calories, we need to run about 5 miles (8km)?
Psychologists say that we devote so much time to adopt one healthy habit that we can’t do the same with another one. This means that we have to decide in which we must concentrate first – a healthy diet or exercise?
Unconsciously, when we start exercising we increase our food consumption thinking that we are burning those extra calories. The truth is that those who don’t watch their daily diet usually consume an average of 2800 up to 4000 calories. This makes it impossible to have the time to burn so many calories daily by exercising.
The tips for a healthy diet are in small portions, unprocessed foods, and 4-5 courses a day. We must keep in mind that exercise lowers the chance for chronic diseases and a healthy diet helps to keep our weight stable ensuring health and satisfaction.
In conclusion, all kinds of physical activities are good for our health, but to control our weight we should be eating properly and in moderation. This is so simple in theory and difficult in practice. Who can resist so many flavors and goodies? But it is tastier when you try and achieve your goals.
