Doctor Says 2 ‘Simple’ Food Mistakes Are Driving Rise in Obesity and Diabetes
For years, doctors have warned that nutrition plays a decisive role in long-term health, but recent trends suggest that this message is more urgent than ever. According to Dr. Frank Dumont, an internal medicine physician and executive medical director at Virta Health, modern eating habits are closely linked to the sharp increase in obesity, diabetes, autoimmune disorders, and even certain cancers seen over the past decades.
Dr. Dumont points out that lifestyle changes, particularly around food choices, have transformed the way people nourish their bodies. Diets today rely far more on processed products than they did in previous generations, with a notable rise in foods rich in simple carbohydrates and added sugars.
These shifts, he explains, contribute to metabolic stress. Highly processed foods can trigger repeated insulin spikes and chronic inflammation, two factors associated with a wide range of health complications. While medication remains important in many cases, Dumont emphasizes that daily dietary decisions often set the foundation for either disease prevention or progression.
Rethinking Fruit and Sugar Intake
One of the most common nutritional missteps, according to Dumont, is choosing fruit juice instead of whole fruit. Although juices contain vitamins and minerals, the processing removes much of the fiber that naturally slows sugar absorption in the body.
Fiber plays a critical role in how the body handles sugar. When fruit is eaten whole, its natural sugars are absorbed more gradually, helping maintain balanced blood glucose levels. Juice, on the other hand, delivers sugar quickly, often without the same metabolic benefits.
Dumont stresses that fruit itself should not be treated as an enemy. For most people, especially those without severe insulin resistance, whole fruit can be a valuable part of a healthy diet. The key lies in understanding personal metabolic health and choosing forms of food that support it rather than overwhelm it.
The Hidden Cost of Breaded Meals
Another seemingly small choice with outsized consequences involves breaded and fried foods, particularly popular chicken-based meals. Dumont explains that breaded options are typically high in refined carbohydrates, which can undermine metabolic balance when consumed regularly.
A simple adjustment, such as choosing grilled chicken instead of fried, can significantly improve the nutritional quality of a meal. When paired with vegetables or leafy greens and a balanced dressing, this alternative offers protein and nutrients without unnecessary additives.
Even when eating at fast-food restaurants, Dumont believes healthier decisions are possible. Selecting grilled proteins over breaded ones can reduce excess carbohydrates and help maintain steadier energy levels throughout the day.
Food as a Tool for Healing
Throughout his medical career, Dumont observed that many patients relying solely on medication continued to see their health decline. This pattern led him to explore the deeper impact of nutrition and lifestyle on chronic conditions.
Contrary to what he was taught during his training, Dumont found that people are capable of sustaining meaningful dietary changes when given clear, practical information. When individuals understand how food interacts with their bodies, healthier choices become both manageable and satisfying.
Today, Dumont sees patients regain confidence as they learn to listen to their own physiological responses. By aligning nutrition with individual needs, many experience improvements that once seemed out of reach. For him, this shift represents a powerful reminder that informed eating habits can be just as transformative as medical treatments.
