TLDR:
Veterans and civilians have similar obesity rates overall, but veterans show slightly higher rates of combined overweight and obesity in several studies. Obesity among veterans has risen over time, with recent estimates around 32 to 33 percent. Some evidence shows a spike in weight gain after leaving military service, making the post-discharge period a high-risk time for developing obesity.
Summary Comparison Table — Veterans vs General/Non-Veteran Adults
Source / Study (Year & Population) Overweight or Overweight + Obese (BMI ≥ 25) Obese (BMI ≥ 30)
Veterans Health Administration (2014 estimate) — U.S. Veterans Approximately 78 percent overweight or obese Included within the above estimate
2004 Behavioral Risk Factor Surveillance System (BRFSS) — U.S. Veterans Males: 73.3 percent; Females: 53.6 percent Males: 25.3 percent; Females: 21.2 percent
2018–2020 National Survey of Veterans (reported in a 2020 study) — Approximately 32.7 percent obese among veterans
2013 Census-based study of Veterans vs Civilians Veterans: Men 76.1 percent; Women 64.0 percent. Non-Veterans: Men 69.9 percent; Women 56.9 percent Not separately specified in this source
General U.S. adult population (2015–2016, CDC/NCHS) Approximately 71.6 percent had BMI ≥ 25 Approximately 39.8 percent obese

Notes on Interpretation
The 2004 BRFSS study concluded that after adjusting for age, s*x, sociodemographic factors, and health status, veterans were no more likely than non-veterans to be overweight or obese.
More recent data suggests obesity prevalence among veterans has increased, with one 2020 study reporting approximately 32.7 percent obesity among U.S. veterans.
Some analyses show a higher combined overweight and obesity rate among veterans compared to civilians. For example, one study found 76.1 percent of male veterans were overweight or obese, compared to 69.9 percent of male non-veterans; for women, 64.0 percent of veterans versus 56.9 percent of non-veterans.
General population statistics come from nationally representative data. Because the veteran population tends to be older and more male than the general population, meaningful comparisons should ideally adjust for these demographic differences.

What This Table Suggests (and Its Limitations)
In the early 2000s, overweight and obesity rates among veterans were generally similar to the U.S. adult population after adjusting for demographic factors.
More recent data indicates rising obesity rates among veterans, with current estimates around 32.7 percent, which is close to or slightly below general U.S. obesity rates depending on the year and the survey used.
Combined overweight and obesity (BMI ≥ 25) may be slightly more common among veterans compared to non-veterans, though results vary depending on the study methodology, sample population, and the extent of demographic adjustments.
One longitudinal study found that many service members experience a significant period of weight gain shortly after discharge. This post-service transition period appears to be a particularly high-risk window for accelerated weight gain compared to active-duty conditions.
