Leading Causes of Weight Gain and Obesity

Obesity is one of the biggest health problems in the world.

It’s associated with several related conditions, collectively known as metabolic syndrome. These include high blood pressure, elevated blood sugar and a poor blood lipid profile.

People with metabolic syndrome are at a much higher risk of heart disease and type 2 diabetes, compared to those whose weight is in a normal range.

Over the past decades, much research has focused on the causes of obesity and how it could be prevented or treated.

Many people seem to think that weight gain and obesity are caused by a lack of willpower.

That’s not entirely true. Although weight gain is largely a result of eating behavior and lifestyle, some people are at a disadvantage when it comes to controlling their eating habits.

The thing is, overeating is driven by various biological factors like genetics and hormones. Certain people are simply predisposed to gaining weight .

Of course, people can overcome their genetic disadvantages by changing their lifestyle and behavior. Lifestyle changes require willpower, dedication and perseverance.

Nevertheless, claims that behavior is purely a function of willpower is far too simplistic.

They don’t take into account all the other factors that ultimately determine what people do and when they do it.

Here are 10 factors that are leading causes of weight gain, obesity and metabolic disease, many of which have nothing to do with willpower.

1. Genetics
Obesity has a strong genetic component. Children of parents with obesity are much more likely to have obesity than children of lean parents.

That doesn’t mean that obesity is completely predetermined. What you eat can have a major effect on which genes are expressed and which are not.

Non-industrialized societies rapidly develop obesity when they start eating a typical Western diet. Their genes didn’t change, but the environment and the signals they sent to their genes did.

Put simply, genetic components do affect your susceptibility to gaining weight. Studies on identical twins demonstrate this very well .

2. Engineered Junk Foods
Heavily processed foods are often little more than refined ingredients mixed with additives.

These products are designed to be cheap, last long on the shelf and taste so incredibly good that they are hard to resist.

By making foods as tasty as possible, food manufacturers are trying to increase sales. But they also promote overeating.

Most processed foods today don’t resemble whole foods at all. These are highly engineered products, designed to get people hooked.

3. Food Addiction
Many sugar-sweetened, high-fat junk foods stimulate the reward centers in your brain .

In fact, these foods are often compared to commonly abused drugs like alcohol, cocaine, nicotine and cannabis.

Junk foods can cause addiction in susceptible individuals. These people lose control over their eating behavior, similar to people struggling with alcohol addiction losing control over their drinking behavior.

Addiction is a complex issue that can be very difficult to overcome. When you become addicted to something, you lose your freedom of choice and the biochemistry in your brain starts calling the shots for you.

4. Aggressive Marketing
Junk food producers are very aggressive marketers.

Their tactics can get unethical at times and they sometimes try to market very unhealthy products as healthy foods.

These companies also make misleading claims. What’s worse, they target their marketing specifically towards children.

In today’s world, children are developing obesity and becoming diabetic and addicted to junk foods long before they’re old enough to make informed decisions about these things.

5. Insulin
Insulin is a very important hormone that regulates energy storage, among other things.

One of its functions is to tell fat cells to store fat and to hold on to the fat they already carry.

The Western diet promotes insulin resistance in many overweight and individuals with obesity. This elevates insulin levels all over the body, causing energy to get stored in fat cells instead of being available for use .

While insulin’s role in obesity is controversial, several studies suggest that high insulin levels have a causal role in the development of obesity .

One of the best ways to lower your insulin is to cut back on simple or refined carbohydrates while increasing fiber intake .

This usually leads to an automatic reduction in calorie intake and effortless weight loss — no calorie counting or portion control needed .

6. Certain Medications
Many pharmaceutical drugs can cause weight gain as a side effect .

For example, antidepressants have been linked to modest weight gain over time .

Other examples include diabetes medication and antipsychotics .

These drugs don’t decrease your willpower. They alter the function of your body and brain, reducing metabolic rate or increasing appetite

7. Leptin Resistance
Leptin is another hormone that plays an important role in obesity.

It is produced by fat cells and its blood levels increase with higher fat mass. For this reason, leptin levels are especially high in people with obesity.

In healthy people, high leptin levels are linked to reduced appetite. When working properly, it should tell your brain how high your fat stores are.

The problem is that leptin isn’t working as it should in many people who have obesity, because for some reason it cannot cross the blood-brain barrier (16Trusted Source).

This condition is called leptin resistance and is believed to be a leading factor in the pathogenesis of obesity.

8. Food Availability
Another factor that dramatically influences people’s waistline is food availability, which has increased massively in the past few centuries.

Food, especially junk food, is everywhere now. Shops display tempting foods where they are most likely to gain your attention.

Another problem is that junk food is often cheaper than healthy, whole foods, especially in America.

Some people, especially in poorer neighborhoods, don’t even have the option of purchasing real foods, like fresh fruit and vegetables.

Convenience stores in these areas only sell sodas, candy and processed, packaged junk foods.

How can it be a matter of choice if there is none?

9. Sugar
Added sugar may be the single worst aspect of the modern diet.

That’s because sugar changes the hormones and biochemistry of your body when consumed in excess. This, in turn, contributes to weight gain.

Added sugar is half glucose, half fructose. People get glucose from a variety of foods, including starches, but the majority of fructose comes from added sugar.

Excess fructose intake may cause insulin resistance and elevated insulin levels. It also doesn’t promote satiety in the same way glucose does .

For all these reasons, sugar contributes to increased energy storage and, ultimately, obesity.

10. Misinformation
People all over the world are being misinformed about health and nutrition.

There are many reasons for this, but the problem largely depends on where people get their information from.

Many websites, for example, spread inaccurate or even incorrect information about health and nutrition.

Some news outlets also oversimplify or misinterpret the results of scientific studies and the results are frequently taken out of context.

Other information may simply be outdated or based on theories that have never been fully proven.

Food companies also play a role. Some promote products, such as weight loss supplements, that do not work.

Weight loss strategies based on false information can hold back your progress. It’s important to choose your sources well.

The Bottom Line
If you have concerns about your waistline, you should not use this article as an excuse to give up.

While you can’t fully control the way your body works, you can learn how to control your eating habits and change your lifestyle.

Unless there is some medical condition getting in your way, it is within your power to control your weight.

It often takes hard work and a drastic lifestyle change, but many people do succeed in the long run despite having the odds stacked against them.

The point of this article is to open people’s minds to the fact that something other than individual responsibility plays a role in the obesity epidemic.

The fact is that modern eating habits and food culture must be changed to be able to reverse this problem on a global scale.

The idea that it is all caused by a lack of willpower is exactly what food producers want you to believe, so they can continue their marketing in peace.
