In recent years, weight-loss injections, like Mounjaro and Wegovy, have been hailed as breakthrough solutions for those struggling with obesity.
But are these drugs really the miracle they’re cracked up to be, or is there a darker side to their rapid weight loss claims? As more research comes to light, concerns are growing that these jabs may be doing more harm than good.
The Weight Loss Miracle or Temporary Fix?
A recent study published in The BMJ delivered some unsettling news about the long-term effects of GLP-1 agonists, the class of drugs that includes popular brand names like Wegovy.
The findings suggest that people who lose weight on these injections are likely to regain it within 18 months of stopping treatment, and perhaps even faster than those who lost weight through traditional methods.
Not only is the weight likely to return, but any cardiovascular benefits—such as improved cholesterol levels—seem to vanish as well.
This study has added fuel to the fire for critics, particularly two prominent doctors, Paul Barrington Chell and Monique Hope-Ross, whose recent book Beyond Weight-Loss Jabs takes an in-depth look at the potential risks of these drugs.
Muscle Loss and Fat Gain: The Unseen Damage
Barrington Chell and Hope-Ross aren’t just concerned about the weight returning after stopping the injections; they’re deeply worried about what that weight is made of.
Research has shown that a significant portion of the weight lost on GLP-1 jabs comes from lean tissue mass, not just fat.
When the weight inevitably comes back, it tends to be in the form of fat, while the muscle mass doesn’t regenerate.
“Your fat mass is increasing, and your lean tissue mass is decreasing.
And that’s a very frightening thought,” says Dr. Paul Barrington Chell.
The impact on the body is potentially devastating, as the loss of muscle and the gain of fat can accelerate the decline in physical health, making people more susceptible to long-term issues.
Nausea, ‘Composting Stomachs,’ and Other Side Effects
Anyone who has taken these weight-loss injections is familiar with the common side effect of nausea, with up to 70% of users reporting it.
But what many don’t realize is that this isn’t just an annoying inconvenience—it’s a sign that the drug is delaying gastric emptying.
“Your stomach is essentially composting the food inside,” explains Dr. Hope-Ross. This slowed digestion means food can sit in the stomach for up to nine hours, causing discomfort and even producing unpleasant symptoms like sulphur burps.
Furthermore, the effect on the body isn’t limited to the stomach.
Dr. Barrington Chell warns that long-term use can also result in muscle atrophy.
“The only way to fix muscle loss caused by these injections is strength training—three times a week for 18 months,” he notes.
But with users already suffering from fatigue due to poor nutrition, sustaining that level of exercise can be incredibly difficult, if not impossible.
Bone Density and Long-Term Health Risks
Another concerning side effect of these injections is the risk of osteopenia, or reduced bone density, which could lead to osteoporosis and increase the likelihood of falls and fractures.
Dr. Barrington Chell asks, “How the hell do you replace the bone?” This loss of bone strength is a serious concern, especially when the long-term effects of these drugs are still not fully understood.
Despite the visible results on the scale, these injections don’t address the underlying causes of obesity.
“Thin does not equal healthy,” says Barrington Chell.
His point? Just because someone sheds pounds with these injections doesn’t mean their body is operating in a truly healthy way.
The cellular damage caused by the drugs may only emerge later in life.
Mental Health and Emotional Toll
Beyond the physical effects, there’s also the impact on mental health.
Weight-loss injections influence the brain’s dopamine system, reducing the ‘food noise’ that typically drives cravings.
While this might seem like a good thing for some, it’s not without its emotional consequences.
Dr. Barrington Chell argues that this dampening effect on dopamine can make life feel less enjoyable, affecting everything from food to hobbies.
The result? Users may lose their ability to find pleasure in the things they once enjoyed.
Recent studies have raised alarm bells about the increased risk of depression, anxiety, and even suicidal thoughts among those using GLP-1 drugs.
Between 2018 and 2023, there were 230 reports of suicidal events linked to these drugs.
While this is still rare, the risks are enough to make anyone reconsider.
A Better Solution? Lifestyle Change Over Medication
Rather than relying on these controversial injections, Dr. Barrington Chell and Dr. Hope-Ross advocate for a more natural approach to weight loss: dietary changes, intermittent fasting, and exercise.
Their plan isn’t about restricting calories or depriving yourself—it’s about training your cells to burn fat more effectively.
They suggest starting with a high-fat, low-carb diet to teach the body to become ‘fat adaptive,’ followed by intermittent fasting.
Fasting, they say, helps regulate insulin levels and forces the body to use fat as its primary energy source.
While fasting may seem daunting, Dr. Hope-Ross notes that the benefits are worth it.
“We fast for five to seven days four times a year, and we feel a sense of calm afterward,” she says.
In addition to diet and fasting, the doctors recommend strength training to combat muscle loss, as well as reducing stress to keep cortisol levels in check.
This holistic approach targets the root causes of obesity, rather than just masking the symptoms with medication.
The Bottom Line: Proceed with Caution
The market for weight-loss injections is booming, but so are the growing concerns.
While these drugs may help users lose weight in the short term, the long-term consequences—ranging from muscle loss and bone density issues to mental health concerns—remain largely unknown.
As Barrington Chell and Hope-Ross caution, “GLP-1 injections are a quick fix, but they don’t teach healthy habits, and they don’t address the real causes of obesity.”
For those seeking lasting change, the solution may lie not in a quick-fix injection, but in long-term lifestyle adjustments—ones that build a sustainable, healthy body from the inside out.
