Strategies for healthcare professionals to help patients maintain weight loss

Why is long-term weight loss maintenance so challenging for patients?

Long-term weight loss maintenance is challenging because both biological and psychological factors drive patients to regain lost weight. Biologically, after weight reduction, the body adapts by burning fewer calories and increasing hunger, creating a “metabolic storm” that promotes regain.¹ only 20% of people who lose weight will maintain it, while the majority return to their original weight or higher.^1,2 Psychologically, sustained motivation is important for achieving weight loss. A supportive communication between healthcare professionals and patients that does not stigmatize weight gain and focuses on its management can help establish realistic weight-loss goals and enable tailored guidance and treatment options.³

What psychological factors influence weight regain?

Behavior and psychological factors play a critical role in weight maintenance. An “all-or-nothing” mindset, where one dietary lapse feels like total failure, is associated with rigid dietary restrain impeding a person’s ability to maintain a healthy weight.⁴ By contrast, patients who practice flexible restraint and self-compassion are more resilient.⁵ Emotional triggers such as stress, loneliness, or boredom also contribute to overeating, particularly when food becomes a coping tool.⁶ Repeated weight cycling can erode confidence and create learned helplessness. Healthcare professionals can help patients reframe lapses as learning experiences rather than failures, fostering self-efficacy and perseverance, essential traits in long-term success.⁷

How can healthcare professionals keep patients motivated to maintain weight loss?

Healthcare professionals can maintain patient motivation through ongoing, empathic communication and behavioral reinforcement.^3,7 Regular follow-ups, even brief digital check-ins, reinforce accountability and normalize the ups and downs of weight control. Motivational interviewing is particularly effective. It is a communication style that helps healthcare professionals and patients understand patients’ situation, realities, and barriers for behavior changes that are required to improve health outcomes.^3,8 Clinicians should emphasize non-scale victories, such as improved energy, reduced joint pain, or lower blood pressure — rather than focusing solely on numbers.⁹ Cognitive-behavioral strategies, including self-monitoring, stress management, and setting realistic goals, enhance commitment. Evidence suggests that patients who sustain weight loss for two to five years have a significantly greater chance of maintaining it for life.¹⁰

What is the “yo-yo effect” and how can it be prevented?

The “yo-yo effect,” or weight cycling, refers to the repeated pattern of losing and regaining weight. This phenomenon often results from restrictive dieting and psychological fatigue. Research has shown that around 20% of overweight individuals are successful at long-term weight loss (when defined as losing at least 10% of initial body weight and maintaining the loss for at least 1 year).² Physiologically, weight loss triggers compensatory changes in biological pathways associated with energy expenditure, energy storage, and appetite,¹ while psychologically, the deprivation of rigid diets triggers rebound overeating.⁴

To prevent weight cycling, healthcare professionals should help patients:

• Adopt sustainable habits rather than short-term diet plans.¹¹
• Practice self-monitoring through regular weight checks and meal logs.¹⁰
• Engage in daily physical activity, about 60 minutes of moderate exercise, to maintain metabolism.²
• Develop coping strategies for stress and emotional triggers.¹²
• Participate in long-term maintenance programs or support groups.¹³

Ultimately, the goal is to normalize consistency over perfection and frame weight management as an ongoing, empowering process.

What kind of long-term support improves outcomes?

Long-term weight maintenance is more successful when healthcare professionals provide structured, continuous support. Obesity is a chronic condition that requires ongoing management, not a one-time intervention.¹⁴ Regular follow-ups every one to three months reinforce adherence and allow early course correction.¹⁴

1. Promote Evidence-Based Behaviors²

• Encourage high levels of physical activity (≈1 hour/day of moderate-intensity activity like brisk walking).
• Recommend a low-calorie, low-fat diet and help patients plan sustainable meal patterns.
• Stress the importance of eating breakfast daily to maintain energy balance.
• Advise regular self-monitoring of weight (daily or weekly) to detect early weight regain.
• Support consistent eating patterns across weekdays, weekends, and holidays.

2. Address Psychological and Behavioral Factors²

• Screen for and manage depression and dietary disinhibition (loss of control over eating), as these predict weight regain.
• Teach relapse prevention skills: catching small weight gains early and taking corrective action.

3. Leverage “Teachable Moments”²

• Use medical triggers (e.g., diagnosis, physician advice) as opportunities to motivate patients for lifestyle change.

4. Provide Long-Term Support¹⁴

• Offer ongoing follow-up beyond the initial weight loss phase to reinforce behaviors.
• Encourage cognitive restraint (conscious control over eating) without promoting rigid or extreme dieting.

Implementation Tips for Clinicians

• Use open-ended questions to evoke reflection and motivation.⁸
• Reinforce autonomy and self-efficacy to sustain engagement.⁸
• Highlight non-scale victories to maintain morale.⁹
• Encourage self-monitoring and flexible thinking.¹⁰
• Maintain an empathic, collaborative tone to reduce stigma and promote trust.⁸
