Muscle is Medicine
Muscle is far more than strength. It is the body's largest metabolic organ and the main site for blood-sugar disposal. It is also a key driver of mobility, balance, and long-term health. When the muscle mass declines, the body ages faster. Conversely, a decent muscle mass prolongs life expectancy.
In the UK, GLP-1 therapies have revolutionised weight management. These medications help reduce excess fat. However, they also suppress appetite to the point where muscle loss becomes a real risk, especially in adults over the age of 40. Research shows that GLP-1 users may lose considerable amounts of fat-free mass unless they're supported with resistance exercise and targeted nutrition.
What does Ageing and GLP-1 Use Mean for Muscle
Understanding the impact of aging and medication on muscle health
From midlife onwards
Muscle mass declines physiologically. According to studies, people are expected to lose 3–8% of muscle mass per decade after the age of 40. This rate accelerates more after the age of 60. GLP-1 medications compound this effect as they reduce calorie and protein intake. Over time, this can weaken strength, slow metabolism, increase fall risk, and make weight regain more likely once the treatment stops.

Muscle Is Medicine: What It Means for You
| Principle | Why It Matters | What FORZET™ Supports |
|---|---|---|
| Muscle drives metabolism | More muscle = higher resting calorie expenditure. | Helps maintain lean mass during reduced appetite. |
| Muscle protects movement and balance | Strength reduces falls, injury risk, and frailty. | Supports functional capacity and energy. |
| Muscle regulates blood sugar | The main site of glucose uptake after meals. | Supports metabolic control alongside GLP-1 therapy. |
| Muscle reduces weight-regain risk | More muscle = less rebound after GLP-1 discontinuation. | Helps stabilise body composition long-term. |
FORZET™ During and After GLP-1 Therapy
During treatment
- Supports preservation of lean mass.
- Helps counter metabolic slowdown.
- Improves the quality of weight loss (more fat will be lost than muscle).
After treatment
- Reduces the likelihood of fat-dominant rebound weight gain.
- Supports strength, energy, and physical confidence.
- Helps maintain long-term healthspan and not just weight change.
