Evidence-Based Strategies to Maintain Weight After GLP-1

In my previous post, I explained why the maintenance phase of GLP-1 therapy stands on its own. Now let’s get into the core strategies people use to maintain their progress during this crucial phase.

There is no single official or universally standardized maintenance protocol for GLP-1 medications. However, expert advice, clinical studies and updated medical guidelines offer a helpful framework to guide your approach. These insights allow you and your healthcare provider to customize an approach that suits your personal needs. to develop a strategy tailored to your individual situation.

Important: Maintenance strategies must be tailored in close partnership with your healthcare provider. Your unique response patterns, medical history, and health goals matter. This overview serves only as a basic starting point to help guide your discussions - it is not a medical advice.

Strategy 1: Continuing Medication (The Clinical Standard)

This is the most evidence-based approach and the one recommended by most obesity medicine specialists. The rationale is simple: if you have a chronic disease, you continue the treatment that manages it.

Within this continuing taking meds strategy, there are three common variations:

✓ Titrating Down to a Lower Maintenance Dose

The core of this strategy is finding the lowest effective dose. The ideal maintenance dose differs for each person, based on how they respond and tolerate the medication.

Usually, the dose is gradually lowered from the higher levels used during active weight loss. This step-down method lets the patient and doctor track changes in weight, appetite and the crucial food noise.

For instance, a patient might find that a lower dose of tirzepatide, such as 10mg, 7.5mg, or even 5mg, is sufficient to sustain the therapeutic benefits. A lower maintenance dose should keep the food noise manageable, helping prevent old eating habits and weight regain.

✓ Spacing Out Injections

Instead of weekly injections, patients extend the interval to every 10, 12 or 14 days. This is done to make prescriptions last longer, combating cost while finding a "sweet spot" of appetite suppression. This approach is highly anecdotal and requires careful monitoring for the return of appetite. Some patients use this method during insurance transitions, though it may compromise effectiveness.

✓ Staying on the Highest Effective Dose

Many patients remain on the dose that helped them achieve their goal weight, such as 2.4mg Wegovy or 15mg Zepbound/Mounjaro. This provides the maximum continued benefit for appetite suppression and glycemic control. While medically robust, this strategy is often limited by cost, insurance coverage and tolerability of side effects.

Strategy 2: Discontinuing Medication (Weaning Off)

This involves transitioning off the GLP-1 entirely, with the goal of maintaining weight through lifestyle alone. While appealing, it is the most challenging path with sobering evidence about long-term success.

It is ideal for people who’ve adopted healthier eating, regular exercise, and stress management while on GLP-1 therapy, and who have steady support from coaches, nutritionists or community. This is for those who stay honest with themselves about relapse risks and know their body well.

From what the data shows, only about 10-20% of people manage to keep the weight off after stopping GLP-1s.

In the STEP-1 trial with Semaglutide (Wegovy), weight climbed quickly after patients switched to placebo. The same pattern showed up in the SURMOUNT-4 trial for Tirzepatide (Mounjaro), with a 14% regain over a year. Even long-term users in SURMOUNT-1 regained weight after stopping.

Practical Considerations for Weaning

• Taper Slowly: Most who attempt this do so by gradually weaning down the dose and spacing out injections over several months. Abruptly stopping from a maximum dose is highly discouraged.

• The 5-Week Rule: It takes approximately 5 weeks for the medication to fully clear your system. You may not feel the full physiological effect of a dose change (like the return of food noise) until your body's drug levels drop zero.

• Track Relentlessly: During a taper, data is your safety net. Weigh yourself daily, log your food intake and monitor hunger cues. This helps you spot trends early before the scale creeps up or old habits creep back in. If you see a pattern forming, you can course-correct quickly.

Strategy 3: Bridging to Alternative Anti-Obesity Medications

This is an emerging strategy aimed at maintaining weight loss after stopping a GLP-1, often using older, more affordable generic medications. A recent study explored this approach and demonstrated initial success, offering hope for patients who lose insurance coverage or cannot afford long-term GLP-1 treatment.

The study method involved patients who had lost weight on a GLP-1 being switched to a combination of other anti-obesity medications for maintenance. The most common medications used were metformin, topiramate, and bupropion. Phentermine was also used but often avoided in primary care due to its status as a controlled substance. Naltrexone was also incorporated into treatment regimens.

Key findings: Patients often required more than one of these generic medications to successfully maintain their weight loss. However, it is a small study, and this approach requires careful medical supervision and management of multiple medications.

Making Your Decision: A Personalized Approach

Choosing a maintenance strategy is not a one-size-fits-all decision. It should reflect your individual circumstances, medical history and personal preferences. Consider how well you tolerate your current medication, your insurance coverage situation, the strength of your cravings, your support system and your preparedness for potential weight regain scenarios.

It is a critical conversation to have with your healthcare provider, weighing the scientific evidence against your personal circumstances.

Remember: chronic weight management often requires ongoing intervention, just like other chronic conditions. This isn't about willpower - it's about finding sustainable, personalized strategies that fit your life and individual biological needs.
