The rapid rise of weight-loss injections is creating an unexpected boom for Britain's fitness industry, as users flock to gyms to combat the muscle-weakening side effects of these powerful slimming drugs.
Gyms across the UK are reporting a significant increase in memberships and personal training sessions from people using medications like Wegovy and Ozempic. These users are discovering that while the injections effectively reduce appetite and promote weight loss, they also cause concerning muscle depletion alongside fat reduction.
The Protein Priority
Fitness professionals note that clients on these medications are particularly focused on strength training and protein consumption. "We're seeing people who've never set foot in a gym before, now committed to resistance training programmes," explains a London-based personal trainer. "They understand that preserving muscle is crucial for both appearance and long-term health."
Supplement Sales Soar
The trend has also boosted sales of protein supplements and created new demand for specialised fitness guidance. Many gyms are developing specific programmes tailored to users of weight-loss medications, focusing on muscle preservation and metabolic health.
Nutritionists emphasise that without proper exercise and protein intake, up to 30-40% of weight lost through these medications can come from muscle tissue rather than fat. This muscle loss can slow metabolism and increase the likelihood of weight regain once treatment ends.
Industry Adaptation
Smart gym owners and personal trainers are capitalising on this emerging market by offering targeted services. From specialised nutrition plans to muscle-preservation workout regimes, fitness professionals are adapting their expertise to meet this new demand.
As one health club manager in Manchester noted: "These members are often highly motivated and consistent with their attendance. They're investing in their health in multiple ways, and we're here to support that journey."
The phenomenon represents a silver lining for the fitness sector, which faced significant challenges during pandemic lockdowns. Now, as weight-loss injections become more accessible through NHS prescriptions and private providers, gyms are positioned to become essential partners in sustainable weight management.
