Diabetes and Nutrition: Adequate Nourishment During Weight Loss

March is one of my favorite months. Along with several family birthdays, it is also National Nutrition Month. Established by the Academy of Nutrition and Dietetics, this annual campaign encourages individuals and communities to make informed food choices and build sustainable eating habits. This year’s theme, “Discover the Power of Nutrition,” aligns closely with the direction of the American Diabetes Association 2026 Standards of Care.

To celebrate, each week this month I will take a closer look at updates to nutrition guidance in Section 5 of the 2026 Standards. This week, we will explore shifts in the language and recommendations around intentional weight loss, including the importance of using an interdisciplinary approach and actively screening for malnutrition.

Raising the Standard for Weight Management

With the launch of ADA’s new division, the Obesity Association, there is a clear emphasis on obesity as a chronic disease that requires long-term, person-centered care. The updated guidance reinforces that weight loss remains a cornerstone of cardiometabolic risk reduction, while also raising the bar on what we should be targeting and how we support people in getting there.

Consider a Higher Baseline Weight Loss Target

The 2025 ADA Standards of Care recommended that individuals with overweight or obesity aim for at least 3–7% weight loss. The 2026 Standards were revised to recommend a treatment plan that aims for at least 5–7% weight loss from baseline body weight.

While not a dramatic change, it is clinically meaningful. Evidence consistently shows that achieving at least 5% weight loss can improve glycemia, blood pressure, cholesterol, and overall cardiometabolic risk.

The updated language also emphasizes that weight management should not be passive or incidental. It should involve a structured treatment plan that integrates:

The behavioral health component is particularly important. Sustainable weight loss is not simply about calorie reduction. It requires attention to eating patterns, stress, sleep, medication effects, and psychosocial factors.

A Stronger Emphasis on Nutritional Adequacy

Previously, the Standards explicitly advised screening for malnutrition, particularly after metabolic surgery or with weight loss pharmacotherapy. The updated recommendation shifts the focus to counseling and regularly monitoring individuals who are intentionally losing weight to ensure adequate nutritional intake.

This change reflects the evolving landscape of obesity treatment, including more widespread use of pharmacologic therapies and aggressive caloric restriction strategies. Rapid or significant weight loss, especially when appetite is suppressed, can increase the risk of:

The new guidance calls on clinicians to proactively monitor nutritional adequacy rather than waiting to identify overt malnutrition. This includes assessing protein intake, dietary variety, and key micronutrients, particularly in individuals with reduced overall food intake.

Practical Takeaways for Clinicians

The 2026 updates reinforce a balanced message: pursue meaningful weight loss when appropriate, but do so with clinical oversight and attention to nutritional sufficiency.

- Aim for at least 5-7% weight loss in individuals with overweight or obesity, using a comprehensive and individualized treatment plan.
- Integrate behavioral health strategies alongside nutrition and physical activity recommendations.
- Monitor nutritional adequacy regularly in patients pursuing intentional weight loss, especially those using weight loss medications.
