What is the largest contributing cause of obesity in the United States
One third of the worlds population today is affected by obesity, according to the ndc “In the USA, the most dire projections based on earlier secular trends point to over 85% of adults being overweight or obese by 2030. Although growth trends in developing countries are leveled in the USA the trend is rising.

We and others have found some success with the small changes approach to preventing excessive weight gain. Rodearmel et al. demonstrated in two prospective studies that small changes in diet and physical activity could reduce excessive weight gain in overweight and obese children when delivered as part of a family intervention.60, 61 The ASPIRE trial showed that overweight and obese sedentary adults randomized to a 16-week intervention that used small changes in diet and physical activity lost significantly more weight than both the standard didactic group or control group.62 Although weight loss for the small changes group was small (average of 4.62 kg), it was clinically significant (5% of body weight). Importantly, the small changes group also maintained weight loss, decreased waist circumference, and abdominal fat loss at three months post-treatment
what can be done and individual level to reverse the growing obesity trend in the United States
5.2. Individual Behaviors
In the decades preceding the 21st century, the vast majority of research on obesity risk factors focused on individual-level, largely modifiable behaviors. The role of diet and physical activity in mitigating obesity risk and reducing prevalent obesity have received the most attention, and with good reason: 15% of deaths in 2000 in the USA were attributable to excess weight, owing to poor diet and physical inactivity (38). Caloric intake and expenditure needed for weight maintenance or healthy growth has historically taken center stage (39), and caloric restriction remains today a primary focus of most popular and clinical weight-management and weight-loss approaches.
Beyond overall caloric intake to regulate body weight, a tremendous amount of research has attempted to resolve the roles of diet quality and dietary patterns, including those specifying combinations of macronutrients (40). Evidence from clinical trials have almost universally shown that caloric restriction, regardless of dietary pattern, is associated with better weight outcomes (40). Although the metabolic nuances and relative merits of the differing dietary patterns for various comorbid conditions are still being investigated, the evidence seems to suggest that merely adhering to a diet—nearly irrespective of what type of healthy diet it is—has an impact on weight loss/control (41–43).
For long-term maintenance of healthy weight, evidence from observational cohorts indicate that diets that are considered “healthier” lead to better long-term weight maintenance, or at least mitigate weight gain typically associated with aging through middle age. For example, research in US health professionals pointed to averaged 4-year weight gain throughout middle age as being strongly associated with increasing intake of potato chips and potatoes, sugar-sweetened beverages, and processed and unprocessed red meats, but inversely associated with the intake of vegetables, fruits, whole grains, nuts, and yogurt (44). Specific food groups, such as sugar-sweetened beverages, have received considerable attention largely because added sugar consumption (primarily as sugar-sweetened beverages) has been rising concomitantly with prevalent obesity (45). Indeed, the weight of the evidence about the role of sugar-sweetened beverages in obesity (46,47) is a strong impetus for public health interventions and policies, such as limiting advertising on these beverages as in Mexico (48), attempts to limit beverage sizes permitted for sale as in New York City (49), taxation, eliminating sale in schools, etc.
5.2.2. Physical Activity, Sedentary Behaviors, and Sleep
Personal behaviors beyond diet (physical activity, sleep, sedentary and screen time, and stress) have also been independently associated with weight change and maintenance in adulthood. Combined with diet, these elements have synergistic and likely cumulative effects on an individual’s ability to maintain or obtain a healthy body weight over the life course. Recently reviewed evidence from randomized trials and observational studies support 2008 US recommendations for weight management (50), consistently showing that in general, 150–250 minutes per week of moderate intensity activity is required to prevent weight gain, or aid in weight loss when accompanied by dietary restriction (51). Activity (>250 minutes per week) is associated with weight loss and weight maintenance after weight loss (51). Leisure-time activities involving sitting, but which are not truly restful behaviors, such as getting <6 or >8 hours of sleep in adults and adolescents (44,52–55) or <10–11 hours of sleep in children (52), television viewing or screen time (44,56,57), and other leisure-time sitting (58) are also associated with weight gain.
