Overnutrition Definition

Over-nutrition

When people consumed more food than the body requires, that is referred to as over-nutrition. If people form a habit of eating more than the body requires, this could cause them to gain weight, and later they will become overweight or worse, obese. That is not a good thing as obesity is associated with many non-communicable diseases and could ultimately lead to death. 

The world Health Organization reported the steady increase of over-nutrition and diseases caused by it in developing and in the poorest countries. This is an indication that there is a huge knowledge gap on good nutrition versus bad nutrition and that lack causes people to make poor food and diet choices. 

 

Causes of over-nutrition

There are some underlying causes that could lead to over-nutrition and its diseases. 

Genetics

Although certain people come from families of obese people, it does not mean they will become obese. However, such people will need to be more cautious with what they eat, when they eat and also adopt some physical activities that will prevent gaining weight.

Poor food choices

The people that are too fond of processed, sweetened, saturated and trans fatty acids consume too much calories even though some of these food items seem little, e.g. potato chips, biscuits, chocolate. Moreover, most of these food items are not even filling, and thus people who consume them usually combine these foods with the healthier meals. At the end of the day, these people would have consumed too much calories. 

More importantly, when people are; stressed out, going through some life-challenges and other problems, they tend to confide on comfort foods which seem tasty and cheaper. That’s why most stressed and depressed people become overweight or obese. 

Addiction to food

A certain study confirmed that over-indulgence to processed foods like sweets, pizzas, etc. could be as addictive as abusing substance and alcohol. When people don’t have power over their food choices, they are headed for health disaster and it will be hard to break such bad habits. 

Insulin resistance

Having higher levels of insulin causes your body to store fat cells rather than encouraging the body to use consumed energy. It is therefore advisable to rather eat a low carb diet with more fiber to ensure your insulin levels are normal. Other causes include; 

  • Misinformation
  • Excessive marketing
  • Food availability, etc.
