A comprehensive training program for resident doctors significantly increased their confidence in obesity medicine skills, with 100 percent reporting high or moderate confidence in diet counseling and prescribing weight loss medications after completing the pathway. According to Gram Research analysis of this 2026 study, 83 percent of the 18 residents also said they would likely pursue board certification in obesity medicine, suggesting structured training can help address the shortage of obesity medicine specialists in underserved communities.
Many doctors don’t feel prepared to help patients with weight management, even though obesity affects millions of people. Researchers created a special training program for internal medicine residents at an urban health center to teach them obesity medicine skills. The program combined online learning, hands-on patient care, and preparation for board certification. According to Gram Research analysis, all 18 residents who completed the program reported feeling confident in counseling patients about diet and prescribing weight loss medications. Most residents also said they’d likely pursue official obesity medicine certification. This shows that structured training can help doctors become better equipped to treat obesity.
Key Statistics
A 2026 research article found that 100 percent of 18 internal medicine residents reported high or moderate confidence in counseling patients about diet and nutrition and prescribing anti-obesity medications after completing a comprehensive obesity medicine training pathway.
In a 2026 study of 18 resident doctors at an urban health center, 83 percent said they would likely or very likely take the board certification exam in obesity medicine after participating in a structured training program combining online learning, hands-on clinic experience, and professional development.
A 2026 research article demonstrated that a 1-2 year longitudinal obesity medicine pathway for 18 internal medicine residents resulted in increased self-reported confidence and practice pattern changes in obesity management.
The Quick Take
- What they studied: Whether a special training program could help doctors-in-training feel more confident and skilled at treating obesity and weight management.
- Who participated: 18 resident doctors (PGY2 and PGY3 level, meaning 2nd and 3rd year trainees) in an internal medicine program at an urban health center that serves low-income communities.
- Key finding: 100 percent of residents reported high or moderate confidence in counseling patients about diet and nutrition and prescribing anti-obesity medications after completing the program. Additionally, 83 percent said they would likely or very likely take the board exam to become obesity medicine specialists.
- What it means for you: If you live in an underserved area, this research suggests that training programs like this one could help ensure your doctor has the skills to help you manage weight effectively. However, this was a small study at one location, so results may vary elsewhere.
The Research Details
Researchers created a new training pathway for resident doctors that lasted 1 to 2 years. The program had three main parts: first, doctors learned foundational knowledge through online modules and group discussions about recent research; second, they got hands-on experience by caring for patients at a weight management clinic over time; and third, they completed the professional requirements needed to become board certified in obesity medicine. All 18 residents who participated filled out surveys before and after the program to measure changes in their confidence and practice habits.
This research approach is important because it tests whether a real-world training program actually works in practice. Rather than just teaching doctors in a classroom, this program combined learning with direct patient care, which is often more effective. The study also tracked whether doctors would pursue official certification, showing commitment to the field.
This study has some strengths and limitations to consider. The strength is that it measured actual changes in doctor confidence and behavior through surveys. However, the study only included 18 residents at one health center, so the results may not apply everywhere. The study relied on self-reported confidence rather than testing actual skills, which can sometimes be less reliable. There was no comparison group of residents who didn’t receive the training, so we can’t be completely certain the program caused the improvements.
What the Results Show
After completing the obesity medicine pathway, all 18 residents reported feeling confident or moderately confident in two key skills: counseling patients about diet and nutrition, and prescribing anti-obesity medications. This represents a significant increase from their baseline confidence levels before the program. Additionally, 83 percent of the residents said they would likely or very likely take the board certification exam in obesity medicine, suggesting the program successfully motivated doctors to pursue formal specialization in this field. The residents also reported changes in their actual practice patterns, meaning they were more likely to address weight management with their patients after completing the training.
The study found that the three-part structure of the program (online learning, hands-on clinic experience, and board certification preparation) worked well together. Residents valued the combination of theoretical knowledge and practical experience. The longitudinal nature of the program, where residents cared for the same patients over time, appeared to be particularly valuable for building confidence and skills.
Previous research has shown that many internal medicine programs don’t adequately prepare residents to manage obesity, leaving new doctors feeling unprepared. This study adds to growing evidence that structured, comprehensive training programs can fill this gap. The approach of combining online education with hands-on clinical experience aligns with best practices in medical education.
The study had several important limitations. First, only 18 residents participated, which is a small group. Second, the study only measured self-reported confidence and practice changes, not actual patient outcomes or whether patients lost weight. Third, there was no control group of residents who didn’t receive the training, so we can’t be completely certain the program caused the improvements rather than other factors. Fourth, the study was conducted at one urban health center, so results may not apply to other settings or regions. Finally, the study didn’t follow residents long-term to see if they actually took the board exam or maintained their skills.
The Bottom Line
If you’re a patient seeking weight management help, look for doctors who have received specialized training in obesity medicine or are pursuing board certification in this field. If you’re a medical educator or program director, consider developing a comprehensive training pathway that combines online learning, hands-on clinic experience, and board certification preparation. Confidence level: moderate, based on this single-center study with a small sample size.
This research matters most to medical educators, residency program directors, and patients in underserved communities who need better access to obesity medicine expertise. It’s also relevant to doctors-in-training who want to develop skills in weight management. This research is less directly applicable to patients in well-resourced areas with abundant obesity medicine specialists.
Based on this study, residents completed the pathway over 1 to 2 years and showed increased confidence by the end of that period. If you’re seeking obesity medicine care, you might expect a doctor trained through such a program to be ready to help within 2 years of starting the training.
Frequently Asked Questions
How can I find a doctor trained in obesity medicine?
Look for doctors who mention obesity medicine training, are pursuing or have completed board certification in obesity medicine, or work at weight management clinics. Ask your primary care doctor for referrals to obesity medicine specialists in your area.
What should I expect from a doctor trained in obesity medicine?
A trained obesity medicine doctor should discuss diet and nutrition counseling, explain anti-obesity medication options, and create a personalized weight management plan. They should address weight management as a medical condition, not just a lifestyle issue.
Does obesity medicine training actually help patients lose weight?
This study showed that trained doctors feel more confident and change their practice patterns, but it didn’t measure actual patient weight loss outcomes. More research is needed to determine if trained doctors help patients lose more weight than untrained doctors.
Why don’t more doctors receive obesity medicine training?
Many internal medicine residency programs don’t have structured obesity medicine pathways, and obesity medicine isn’t always prioritized in medical education. This study demonstrates the need for more comprehensive training programs like this one.
Can this training program work in other cities and hospitals?
This study was conducted at one urban health center, so results may vary in other settings. However, the three-part structure (online learning, hands-on experience, board certification prep) could potentially be adapted to other locations and residency programs.
