The GLP-1 Secret Doctors Are HIDING
When GLP-1s hit the market, Big Pharma wasn’t just selling drugs…
They were selling a dream.
Just a weekly injection or a daily pill, and watch all of that extra fat melt off your body.
Now, the other shoe has dropped.
Patients’ energy levels are tanking… they’re breaking bones… and even reporting cases of scurvy.
All from dangerous nutritional deficiencies.
And it’s exposing one of the dirty secrets of mainstream medicine…
Most mainstream doctors don’t want to admit it. They’re embarrassed by it.
But they’re not qualified to hand out these drugs and manage the risks.
Let me show you why…
Now, I don’t mean to denigrate my own profession.
I truly believe that most doctors who prescribe GLP-1s mean well. They know how dangerous diabetes and obesity are for your health, and they want to help.
But that’s when things can go off the rails quickly…
GLP-1s can dramatically suppress your appetite and lead to serious nutritional deficiencies.
How much training do most American doctors have to address these problems?
Almost none.
I’m not kidding. Mainstream doctors today get almost no nutritional training during their undergraduate or graduate studies, even though nutrition affects our health more than anything else.
Back in 2017, researchers surveyed doctors from NYU’s Langone Health, including cardiologists. Just 13.5% of these docs felt adequately trained to give nutritional advice to patients.
They’re totally in the dark.
In a 2023 survey of more than 1,000 U.S. medical students, about 58% reported receiving no formal nutrition education during all four years of medical school—and those who did receive any training averaged only about three hours per year.
My own nutritional training in medical school lasted a total of five hours. Three of those hours were on IV nutrition, when patients can’t eat for themselves. For the other two, they dumped a handful of nutrition books in the classroom… and told us they were written by “quacks.”
That was it. I’m serious.
I spent decades studying nutrition on my own, because that was the only way to learn. But many doctors today have been failed by our medical education system and are flying blind.
So it’s no wonder we’re seeing some of these side effects pop up with GLP-1s, including:
- Fatigue (one of the most common side effects)
- Cases of scurvy, a severe vitamin C deficiency
- Increased risk of bone breaks
- Even case reports of sarcopenia, a muscle wasting that can lead to falls and frailty
These are all diseases of nutritional deficiency. Our medical system is ill-equipped to handle them, and patients are not being warned.
If you’re taking a GLP-1, you should be having your nutrient levels checked regularly at a minimum.
But the safest bet is probably to avoid these meds completely.
This isn’t even about whether they work anymore.
It’s about whether we’re capable and trained to handle their aftermath.
And we’re not.
