You’ve probably heard the buzz about weight-loss injections like Ozempic and Wegovy. Maybe you’ve seen celebrities swear by them or read stories about people dropping stones in just a few months. But here’s the real question—are these injections actually worth it?
Yes, they can help with weight loss, but at what cost? Before jumping on the bandwagon, here’s what you need to know.
The Good: What The Research Says
These medications were originally designed to help people with type 2 diabetes, but they’ve quickly gained attention for their weight-loss effects. And there’s solid evidence that they can offer some impressive benefits beyond just shedding pounds:
Better Heart Health – Research shows lower rates of heart attacks, strokes, and high blood pressure in users. Given the link between obesity and heart disease, this is a big win.
Brain & Mental Health Improvements – Studies suggest these drugs may reduce the risk of Alzheimer’s and even help with conditions like schizophrenia, substance abuse, and depression.
Lower Risk of Chronic Diseases – Fewer cases of liver cancer, kidney disease, and bacterial infections have been reported among users, likely due to lower overall inflammation in the body.
Weight Loss That Helps Beyond the Scales – Losing weight can help with conditions like sleep apnea by reducing fat around the airways, improving sleep and overall well-being.
The Downsides: It’s Not All Positive
Like any medication, these drugs come with side effects—and some are more concerning than others.
Muscle Loss & Weakness – The Hidden Risk
One of the biggest red flags emerging from research is that these injections don’t just help you lose fat—they can also cause muscle loss. A study found that up to 40% of weight lost on these drugs comes from lean muscle rather than fat.
And that’s a serious problem. Losing muscle doesn’t just mean you’re getting smaller—it means you’re getting weaker.
Less muscle = less strength & mobility. Struggling to do everyday tasks? Feeling weaker despite losing weight? That could be why.
Your metabolism slows down. Muscle burns calories, even at rest. Losing muscle means your body needs fewer calories, making it easier to regain weight later.
Loss of independence. As we age, muscle loss becomes even more of a concern. Strength isn’t just about looking toned—it’s about being able to move well, stay active, and feel good in your body.
Digestive Issues – Many people report nausea, stomach pain, and conditions like diverticulitis or haemorrhoids, making the medication hard to tolerate.
Joint Pain & Arthritis – Surprisingly, some users have reported increased joint pain and arthritis, even though weight loss usually helps relieve joint strain. Scientists think this could be linked to inflammation changes caused by the drug.
Other Side Effects – Some people experience low blood pressure (leading to dizziness and headaches), kidney stones, and disrupted sleep patterns.
Should You Consider Weight Loss Injections?
They might be worth it if…
You have type 2 diabetes or obesity-related health risks, and your doctor recommends them.
You’re struggling with weight loss and have already tried sustainable lifestyle changes without success.
You’re aware of the risks and willing to combine medication with strength training and proper nutrition to protect your muscle mass.
Think twice if…
Your weight isn’t seriously affecting your health. The risks might outweigh the benefits.
You’re using them as a ‘quick fix.’ If you don’t change your habits, the weight will likely return.
You’re not planning to support your body with strength training and proper nutrition—losing muscle will make you weaker, not healthier.
The Bigger Picture: Lifestyle Still Wins
At the end of the day, weight-loss injections aren’t a substitute for a healthy lifestyle. If you’re not moving your body, fuelling yourself well, and getting enough rest, these drugs won’t magically fix things.
And let’s be real—who wants to be skinny but weak? Feeling strong, mobile, and energetic should be the real goal.
If you’re looking for real, long-term health improvements, a sustainable approach is key. Strength training, good nutrition, and building habits that work for you are still the foundation of long-term success.
At POWER, we focus on helping people get stronger, feel better, and improve their health in a way that actually lasts. No fads, no gimmicks—just proper training and support that works for real life.
If you’re considering weight-loss injections, ask yourself: What else could I be doing to support my health right now?
Real strength doesn’t come from an injection. It comes from moving better, training smarter, and having the right support. Let’s make that happen.
