Over the previous 12 months, the query has been coming in from in every single place – from my sufferers and members of the family, from colleagues and passengers I chatted with on airplanes: Is Ozempic proper for me? Or any of the blockbuster weight reduction and diabetes medicine that just lately caught the world’s consideration? Whereas filming my new documentary in regards to the medicine, it turned clear that many individuals have at the least thought of taking GLP-1 drugs, drawn to the potential of steadier blood sugar, higher coronary heart well being and particularly weight reduction.
Though weight problems is now probably the most widespread ailments within the developed world, there may be nonetheless a lot debate about how it’s recognized and what precisely causes it. Some consultants query whether or not it’s even a illness in any respect.
All these matters turned the main target of an intense dialogue I had in Copenhagen this spring with Dr. Jens Juul Holst, a Danish scientist who helped uncover the molecules that are actually fully upending the diabetes and weight reduction subject. By now, you’ve gotten certainly heard of Wegovy, Mounjaro, Zepbound and Ozempic. Some say Holst is a future Nobel Prize winner for this work, whereas others say he helped additional gas a wildly costly trade to deal with one thing higher addressed with weight-reduction plan and train.
Holst is a pleasant, energetic, trim and wholesome 79-year-old who nonetheless rides his bike to work day by day. He defined that the unique purpose of a world workforce of researchers was to discover a molecule that would probably deal with peptic ulcer illness, not diabetes or weight problems. Though it wasn’t in the end useful for ulcers, he informed me, it was by way of a collection of serendipitous discoveries that they realized that concentrating on GLP-1 might as an alternative dramatically decrease blood sugar and physique weight. And importantly for a lot of who had struggled with weight problems, these molecules appeared to work when nothing else had. He knew he had helped uncover one thing probably transformative.
When the primary variations of those drugs had been accepted 20 years in the past, you could be stunned to be taught, there was little fanfare. Hardly anybody heard about them throughout these early days. A part of the rationale was the interior handwringing amongst pharmaceutical executives by no means assured folks would inject themselves to drop some pounds — and, sure, amongst scientists like Holst, unclear on what precisely they had been treating.
Weight problems: A illness in and of itself?
For starters, there is no such thing as a query that weight problems is linked to all kinds of different ailments, resembling sort 2 diabetes, most cancers, coronary heart illness and stroke, to call just a few. Nevertheless, that doesn’t imply the hyperlink at all times exists for everybody or that weight problems was by itself the perpetrator. In any case, there are many individuals who have weight problems however don’t have any proof of coronary heart illness or diabetes. Their blood stress is regular, and so they take no drugs. There aren’t any abnormalities of their blood work or impairments of their regular bodily operate. Their solely illness is an elevated BMI — an excessive amount of weight for his or her top.
After I requested Karin Conde-Knape, the pinnacle of drug growth at Novo Nordisk, the maker of Ozempic and Wegovy, about this, she smiled and mentioned, “sure, we name them the ‘completely satisfied overweight.’” The priority, she added, is that “these sufferers are on a trajectory towards growing these different ailments.”
Conde-Knape was suggesting that weight problems ought to nonetheless be labeled as a illness as a result of it should inevitably result in issues — even when it doesn’t proper now. As issues stand now, many main medical organizations, together with the American Medical Affiliation and the World Well being Group, would agree together with her, however it’s nonetheless a wildly polarizing matter that has develop into extra pressing than ever with the introduction of those medicine.
A study printed within the Lancet this week tasks that in 2050, 43.1 million kids and adolescents in the US and 213 million adults can be chubby or overweight. And but, at a time once we can measure particle dimension of small lipid molecules and genotype tumors, it’s outstanding that we nonetheless depend on a primitive methodology referred to as BMI to diagnose weight problems.
BMI, or body mass index, is measured with a formulation first used almost 200 years in the past, when mathematicians – not physicians – had been making an attempt to find out the perfect weight for people; extra particularly, “the quantifiable traits of the conventional man.”
Solely European males had been included within the authentic measurements – no girls, no kids. And it wasn’t till greater than 100 years later, within the Fifties, that insurance coverage corporations realized extra of their claims had been coming from individuals who had been overweight. Earlier than that, nonetheless, there was no acknowledged correlation between BMI and general well being. BMI doesn’t even distinguish between muscle mass and fats mass. That’s why the fittest, most chiseled and health-conscious particular person you realize would possibly nonetheless be thought of overweight.
Holst, together with others, mentioned a greater measure of weight problems could be the straightforward use of a tape measure to test your waist-to-hip ratio, which may assess visceral fats, along with physique mass index.
The controversy about whether or not weight problems must be thought of a illness, particularly as measured by BMI, will most likely proceed. However there may be an space of settlement I discovered with almost everybody I spoke to in regards to the matter: Very like despair and habit are actually described as ailments of the mind, scientists are more and more saying the identical about weight problems – that, for many individuals, being overweight just isn’t a selection or reflective of a scarcity of willpower. And, curiously sufficient, it could be this new class of medicines that basically strengthened this level.
Right here’s why.
The GLP-1 molecules are described as post-nutrient hormones, that means substances the human physique releases after consuming meals. Collectively, they stimulate your pancreas to make extra insulin, decelerate how shortly meals strikes into your intestines and activate areas within the mind that make you are feeling full or satiated.
As a neuroscientist, I discovered this final level notably fascinating. It seems that some folks by no means actually really feel full, regardless of what number of energy they’ve consumed. As an alternative, they’ve a relentless, maddening meals chatter of their brains. Whilst they’re consuming one meal, they’re already occupied with the subsequent one, as an alternative of ever feeling really satiated. It’s a part of the rationale they proceed to eat way more energy than they require. For them, GLP-1 drugs can fairly actually quiet these voices of their head.
Holst can be very targeted on this explicit mechanism of the GLP-1 medicine however worries that it could go too far.
Over a meal of espresso and attractive pastries, he informed me that these medicine appear to remove the enjoyment of meals for some folks. It’s maybe his largest concern. Folks cease socializing as a lot, he informed me, understanding they gained’t be hungry for dinner. They could additionally develop into too skinny too quick and have the related sagging pores and skin and fatigue. For others, it’s the lack of lean muscle mass that accompanies their weight reduction and places them at larger threat for falls. As a result of the drugs work by slowing digestion, horrible constipation turns into a aspect impact that’s an excessive amount of for some to bear.
Take into account this: Greater than half the individuals who begin these drugs find yourself stopping them inside simply 12 weeks. For some, the drugs are too costly and might ultimately develop into out of attain financially. Others develop a tolerance to the medicine, and over time, they might cease working as properly. However for lots of people, it’s these unwanted effects – together with the lack of pleasure – that drives their dissatisfaction with the meds.
And once more, it was that lack of pleasure that was notably regarding to Holst. “It’s a heavy worth to pay,” he informed me.
For now, the query retains coming: Who ought to contemplate taking these medicine? Ought to I attempt these medicine?

There may be little doubt that for most individuals, common train and consuming proper continues to be the most effective technique for weight reduction and general well being. Excessive-fiber diets, for instance are inclined to launch extra pure GLP-1. Amongst individuals who took GLP-1 drugs and stopped, these almost certainly to maintain the load off had integrated way of life modifications in a significant method.
Most individuals do regain weight after stopping the drugs, however importantly, not all folks and never all the load. For these capable of maintain weight off, these drugs weren’t a lifelong resolution, however moderately a burst of motivation to assist reverse their weight problems trajectory.
Sure, now we have numerous work to do in higher defining and assessing weight problems. That’s what Holst actually needed me to know after his many years of labor on the subject. Within the meantime, nonetheless, these drugs would possibly lastly present a lifeline for many who have really struggled for too lengthy.
