According to the Centers for Disease Control and Prevention (CDC), obesity in America is a serious, common, and costly chronic disease.
The prevalence of obesity in the United States has risen sharply under a new definition of the condition released by the Lancet Diabetes and Endocrinology Commission, according to research co-authored by Harvard-Mass General Brigham specialists.
When applying the new criteria, which expand upon the traditional use of body mass index (BMI) to include measures of body fat distribution, the prevalence of obesity increased from 40 percent to 70 percent among more than 300,000 people included in the study. The rise was more pronounced among older adults. (The results are published in JAMA Network Open.)
Lindsay Fourman, a Mass General endocrinologist and assistant professor at Harvard Medical School remarked, “We already thought we had an obesity epidemic, but this is astounding. With potentially 70 percent of the adult population now considered to have excess fat, we need to better understand what treatment approaches to prioritize.”
BMI measured body fat based on a person’s weight and height. The new criteria include other anthropomorphic measures – such as waist circumference, waist-to-height ratio, or waist-to-hip ratio-may further account for fat distribution and aid in differentiation between muscle and fat mass. Over 70 organizations have endorsed the new guidelines including the American Heart Association and the Obesity Society.
The American Society for Metabolic and Bariatric Surgery reports that “leading health organizations around the world recognize obesity as a chronic and progressive disease that stems from a combination of genetic, behavioral and environmental factors. This worsening and highly treatable public health issue is linked to many life-threatening diseases including type 2 diabetes, heart disease, obstructive sleep apnea, high blood pressure, and certain types of cancers.”
Obesity linked to disease:
- Linked to 30-53% of new diabetes cases.
- Increases risk of developing high blood pressure and high cholesterol – both of which make heart disease or stroke more likely.
- Over 70% of individuals with obstructive sleep apnea have clinical obesity.
- Major risk factor for cancer – increases risk for at least 13 types of cancer.
Key Factors Contributing to Obesity
- Diet: High-calorie, low-nutrient foods are widely consumed.
- Physical Activity: Many adults do not meet recommended levels of physical activity.
- Socioeconomic Status: Access to healthy foods and recreational facilities can vary significantly.
Obesity and Diet:
- According to the United Nations, the number of calories individuals in North America and Europe has been rising since 2000, equaling 3,540 per day in 2021.
- When the number of calories a person consumes is greater than the number of calories their body burns – their body stores extra energy as fat which contributes to weight gain.
- The quality of food eaten matters in that many processed foods contain an excess of ingredients like sodium, fat, and sugar. They often contain more calories than needed and are easier to digest, which can contribute to weight gain.
- Eating foods high in refined starch and sugar can raise your insulin, which can make you hungrier – causing you to eat more.
Children and Adolescents:
The CDC published in 2024, that approximately 1 in 5 children and adolescents in the United States have obesity. They reported that obesity affects some groups more than others, including adolescents. Hispanic and Black children, and families with lower incomes have a higher frequency of obesity. Health care for obesity is expensive for patients and the health care system. In 2019, the estimated annual medical cost of obesity among U.S. children was $1.3 billion. Medical costs for children with obesity were $116 higher per person per year than for children with healthy weight. Medical costs for children with severe obesity were $310 higher per person per year than for children with healthy weight.
Coca-Cola – a threat to human health:
Katherine Marengo, LDN, R.D. published a report in Medical News Today on February 10, 2023, entitled “Is Coca-Cola bad for you?”
Sugary drinks can contribute to many health conditions, including obesity, type 2 diabetes, and tooth decay. Research has shown that drinking a can of Coca-Cola can damage the body within an hour. According to the CDC, about half of the United States population will drink at least one sugary beverage on any given day. Young adults are the most regular customers of sugary drinks.
- There are 37 grams of added sugar, which equate to almost 10 teaspoons in a single can of cola.
- British pharmacist Niraj Naik reported that the intense sweetness of Coca-Cola resulting from its high sugar content should make a person vomit as soon as it enters the body. However, the phosphoric acid in the beverage dulls the sweetness, enabling people to keep the drink down.
- Naik further reports that blood sugar levels increase dramatically within 20 minutes of drinking the cola, causing a burst of insulin. The liver then turns the high amounts of sugar into fat.
- The effects of the cola are like heroin. Within 40 minutes, the body absorbs all the caffeine from the cola. This causes the pupils to dilate and blood pressure to increase. By this point, the cola has blocked the adenosine receptors in the brain, preventing drowsiness.
- According to Naik, the effect on the human body applies not only to Coca-Cola but to all caffeinated fizzy drinks.
Supplemental Nutrition Assistance Program (SNAP) – a new aggressive approach.
SNAP (Food Stamps) provides food benefits to low-income families to supplement their grocery budget so they can afford the nutritious food essential to health and well-being.
Food assistance recipients spend about 10 percent of their food budget on sugary drinks, while the rest of the population spends about 7 percent.
The Trump Administration is taking an aggressive approach in public health by approving waivers that allow states to restrict the purchase of junk food and sugary drinks with SNAP benefits. This initiative focuses on improving health and combating chronic childhood diseases. This approach grants states the flexibility to manage SNAP differently.
Obesity accounts for nearly $200 billion in medical annual expenditure. It increases the risk of chronic diseases and can lead to reduced life expectancy. Addressing this issue requires comprehensive personal accountability and responsible public strategies.
