At NativePath, we believe that rising obesity rates are mainly due to changes in the American diet over the last several decades.
As we stated earlier, when it comes to obesity rates by country, the U.S. has one of the highest—with rates increasing by a whopping 300% over the last 60 years. These rates started to see an uptick around the 1970s and 80s, when ultra-processed foods became more common in American households (5).
There are a few reasons why processed foods are detrimental to one’s weight loss journey:
For one, they're made with almost no whole foods. Instead, they’re packed with added sugars, salts, and artificial flavors. Not only that, they also include ingredients you’d never use in your own kitchen (think: artificial sweeteners, bulking agents, coloring agents, modified starches, hydrolyzed proteins, high fructose corn syrup, and hydrogenated oils). Yuck.
Hydrogenated oils are particularly concerning. These chemically processed vegetable oils didn’t even exist until the last hundred years, and serve no natural role in the human diet (6, 7). They are jam-packed into ultra-processed foods like fried food, frozen foods, and even coffee creamers and salad dressings (8, 9, 10). These oils have been linked to heart health issues, chronic inflammation, and yes, obesity.
As life gets increasingly fast-paced, it's enticing to reach for ultra-processed foods because of how convenient they seem. But the reality is that they’re empty calories with no fiber or nutritional value—and they’re destroying the health of our population. Even if you diligently count your calories each day, eating these ultra-processed foods can damage your health and affect your weight (11).
