Some Graphs Showing why we Get Fat

 

Obesity rates have tripled since 1980 and have increased particularly fast in children. This must be due to changes in the environment because our genes don’t change this quickly.

This article contains graphs with historical trends and results from obesity studies, showing some of the main reasons why we get fat.

People Are Eating More Junk Food Than Ever

Food Spending, Smaller
At the turn of the 20th century, people were eating mostly simple, home-cooked meals. Around 2009, about half of what people ate was fast food, or other foods away from home.

This graph actually underestimates the true change, because what people are eating at home these days is also often based on processed foods.

The Obesity Epidemic Started When The Low-Fat Guidelines Were Published

Low Fat Guidelines and Obesity Epidemic

 

There was an epidemic of heart disease running rampant in the U.S. in the 20th century. A lot of scientists believed fat, especially saturated fat, to be the main dietary cause of heart disease (although this has since been disproven). This led to the birth of the low-fat diet, which aims to restrict saturated fat. Interestingly, the obesity epidemic started at almost the exact same time the low-fat guidelines first came out.

Putting the emphasis on saturated fat, while giving processed low-fat foods high in sugar a free pass, may have contributed to negative changes in the population’s diet. There are also massive long-term studies showing that the low-fat diet does NOT cause weight loss, and does not prevent heart disease or cancer.

People Are Drinking More Sugary Drinks and Fruit Juices

Caloric Beverage Consumption in USA

The brain doesn’t “register” liquid sugar calories in the same way as it does solid calories.  That’s why liquid sugar calories are usually added on top of the daily calorie intake. Unfortunately, most fruit juices are no better and have similar amounts of sugar as soft drinks. Studies have shown that a single daily serving of a sugar-sweetened beverage is linked to a 60.1% increased risk of obesity in children.

Sugar is bad… but sugar in liquid form is even worse.

The fats we are eating have changed dramatically in the past 100 years or so.

At the beginning of the 20th century, we were eating mostly natural fats like butter, ghee and lard… but then they were replaced with margarine and vegetable oils. These refined oils are highly inflammatory, leading to disease.

People Are Sleeping Less

Historical Sleep Trends in Hours Per Night
Poor sleep can affect various hormones, contributing to increased hunger and cravings. In recent decades, average sleep duration has decreased by 1-2 hours per night.

Short sleep duration is one of the strongest individual risk factors for obesity. It is linked to an 89% increased risk in children, and a 55% increased risk in adults.

People may argue about the causes of obesity… whether it is sugar, carbs, fat, or something else.But the fact is, the diet and environment have changed has altered the way our brains and hormones work. These changes affect the biological systems that are supposed to prevent us from getting fat. This is the underlying reason for the increased calorie intake and weight gain, NOT a lack of willpower.
