All In regards to the New Weight Loss Medicine

Man sitting in front of coffee table preparing Semaglutide Ozempic injection.The US and far of the industrialized world has an weight problems drawback. The setting is obesogenic. The meals is scrumptious and engineered by PhDs to focus on and titillate our mind reward techniques. The parts are huge. Half of our waking hours are dedicated to sitting slumped over in a chair staring into an digital gadget—for work and for pleasure. We eat carbs we don’t want, use seed oils in portions our our bodies haven’t tailored to dealing with, and largely keep away from an important meals our ancestors developed consuming: animal protein. The most affordable meals is the worst and the healthiest is the costliest.

It’s an enormous mess, and many individuals resist the dietary and way of life adjustments required to repair the difficulty. It’s no surprise many individuals have been hoping for a tablet or medicine that fixes the weight problems drawback. 

Over the previous couple of years, scientists seem to have discovered a category of medicines that may assist: GLP-1 agonists like semaglutide (bought as Ozempic® and Wegovy®) and liraglutide (aka Victoza® and Saxenda®). Hollywood celebrities and trend fashions are taking these medication in huge portions. Silicon Valley tech circles are taking them—Elon Musk, most famously, is on semaglutide. In brief, nearly everybody with the cash and entry and weight to lose is utilizing semaglutide and associated medication to remain skinny. I do know a number of docs who prescribe it for obese sufferers.

Initially designed as diabetes medication, these brokers mimic the consequences of glucagon-like peptide-1, an incretin hormone the physique releases once you eat meals. GLP-1 has two main results:

  • It stimulates the discharge of insulin and inhibits the discharge of glucagon. 
  • It slows down gastric motility and the passage of meals by way of the intestine, maintaining you full for longer. 

GLP-1 is a hormone that “indicators” fullness. There are all types of optimistic downstream results as properly:

  • Decrease glucose manufacturing
  • Extra glucose uptake by muscle mass
  • Elevated insulin sensitivity 
  • Decrease blood stress
  • Improved endothelial operate

The brand new weight reduction medication bind to the receptors that usually work together with GLP-1 and elicit the identical impact because the hormone itself. 

Do the weight problems medication work for shedding weight?

Sure. They work. Out of all the burden loss medication the business has pushed and examined and tried, the GLP-1 agonists truly assist individuals shed extra pounds.

A current paper examined semaglutide for 2 years in overweight individuals. The common beginning physique weight was 106 kilos, or 233 kilos. Common beginning BMI was 38. Most have been girls. One group obtained the drug, the opposite obtained placebo. Each teams have been endorsed to comply with a “behavioral intervention,” which in all probability means train and different typical issues.

By 104 weeks, the semaglutide group had misplaced a mean of 15.2 % of their body weight. The placebo group had misplaced a mean of two.6 %.

Now, this didn’t make them skinny. On the finish, most have been nonetheless obese or overweight. 15 % of 233 kilos is about 35 kilos. That’s a fantastic enchancment, but it surely’s not sufficient to get you to a traditional physique weight. Moreover, there was a significant plateau of weight reduction within the semaglutide group round 68 weeks. They didn’t actually lose any extra weight after that (as a bunch), they usually even began to barely acquire by the top of the research. It was a really minor uptick, however an uptick nonetheless.

Semaglutide wasn’t sufficient for them. They have been nonetheless principally obese, and the burden wasn’t persevering with to return off—and it might have been beginning to come again on.

However these medication aren’t nearly weight reduction. There are different helpful results, too:

  • Diminished blood stress.
  • Fewer cravings for junk meals.
  • Diminished main cardiovascular occasions (coronary heart assaults, strokes, and so on).
  • Higher glucose tolerance.
  • Diminished visceral fats.

So these weight problems medication additionally enhance different well being markers. That’s nice and means that the consequences when you’re taking the drug are principally optimistic.


I see some potential downsides, nonetheless.

Potential Downsides of GLP-1 Agonists

  • You in all probability should take it for all times. A current paper adopted a bunch of people that had taken semaglutide for over a 12 months and misplaced numerous physique weight within the course of. Half of them continued taking the med and the opposite half obtained placebo injections. This went on for 48 weeks. Those that have been nonetheless on the sauce saved a lot of the weight off. Those that went off the drug rapidly regained a lot of the weight and misplaced nearly all the different well being advantages (blood sugar, blood lipids, blood stress, and so on.).
  • It’s costly. A minimum of as of now, the month-to-month price of a GLP-1 agonist subscription is $1500. Insurance coverage might cowl a lot of that, however you must be severely obese or wait til these medication are prescribed for gentle obese—however even then, assuming you will have insurance coverage, somebody’s paying.
  • Liraglutide has been proven to extend adipogenesis, the creation of recent fats cells, no less than in mice. Even because the rodents misplaced weight, they elevated the variety of fats cells of their physique. It is a course of that usually happens in childhood. It’s one purpose why childhood weight problems is so arduous to beat and so usually results in grownup weight problems. You have got a ton of “additional” fats cells from once you have been overweight as a child, so filling them up turns into simpler and simpler. If liraglutide or semaglutide additionally improve the creation of recent fats cells, what occurs once you cease taking it? What occurs in 5 or ten years? Do these “empty” fats cells rapidly refill? It’s an attention-grabbing query we merely don’t know the reply to. But.
  • GLP-1 agonists improve resting coronary heart price, with the longer-lasting variations like injectable semaglutide (the commonest used for weight reduction) resulting in sustained and long-lasting rises in resting coronary heart price. Whether or not this portends a rise in well being points down the street stays to be seen, but it surely’s usually accepted {that a} larger resting coronary heart price is a foul factor.
  • GLP-1 agonists trigger nausea and diarrhea. They’re truly the commonest unwanted side effects individuals complain about, they usually might even contribute to the disinterest in meals individuals report. It’s arduous to be hungry once you really feel like throwing up.
  • GLP-1 agonists trigger lack of lean mass. This isn’t distinctive to GLP-1 agonist-related weight reduction; it’s typical everytime you shed extra pounds, however anecdotally, it doesn’t appear to occur when individuals shed extra pounds following a Primal approach of consuming and exercising. This might doubtlessly be prevented by merely emphasizing protein and ensuring to elevate heavy issues reasonably than counting on the semaglutide to do all of the work.
  • The advantages stage off after about 68 weeks. They could proceed should you bump up the dose, however that may also improve the prospect of unwanted side effects like nausea, diarrhea, and any points associated to elevated adipogenesis.
  • We don’t know what we don’t know. These are pretty new medication and we don’t have any good long run (10 to twenty years) information.

My Last Tackle GLP-1 Agonists

It’s not going to repair weight problems. All of the research discover that it helps customers shed vital physique weight however that there’s a lull within the loss. It’s not sufficient. It’s doesn’t get you previous weight problems and obese into true leanness. To do this, you even have to handle different points of your eating regimen and way of life to actually make the adjustments stick and prolong them into perpetuity.

I do assume it may well assist individuals follow a greater eating regimen. Whereas the fanfare focuses on the truth that you’ll be able to “eat no matter you need” and nonetheless shed extra pounds, it’s additionally been proven to cut back cravings for junk meals and starches. A wise use of this drug can be to pair it with a wholesome low-carb eating regimen primarily based on entire meals that emphasizes animal protein. Complete meals so that you’re getting the micronutrients you want and protein so that you’re getting enough protein to stave off muscle loss.

Finally, most individuals studying this don’t want semaglutide injections. You’re already keen to do the work and make everlasting adjustments to your eating regimen, way of life, and train habits that set you up for long run success. However thousands and thousands of individuals aren’t. Whereas I’ve some main reservations about the long run results of those medication—in any case, I strongly suspect there’s no free lunch in terms of stuff like this—they might be helpful on web to individuals who’d in any other case by no means take into account altering their eating regimen and way of life.
