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 downside. The atmosphere 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 system—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 crucial 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 life-style adjustments required to repair the difficulty. It’s no surprise many individuals have been hoping for a tablet or remedy that fixes the weight problems downside. 

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

Initially designed as diabetes medicine, these brokers mimic the results 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 “alerts” fullness. There are all types of optimistic downstream results as nicely:

  • Decrease glucose manufacturing
  • Extra glucose uptake by muscle groups
  • Elevated insulin sensitivity 
  • Decrease blood strain
  • Improved endothelial perform

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

Do the weight problems medicine work for reducing weight?

Sure. They work. Out of all the load loss medicine the trade has pushed and examined and tried, the GLP-1 agonists really assist individuals shed some pounds.

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

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

Now, this didn’t make them skinny. On the finish, most have been nonetheless chubby or overweight. 15 p.c of 233 kilos is about 35 kilos. That’s a terrific enchancment, but it surely’s not sufficient to get you to a traditional physique weight. Moreover, there was a serious plateau of weight reduction within the semaglutide group round 68 weeks. They didn’t actually lose any extra weight after that (as a gaggle), they usually even began to barely achieve 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 chubby, and the load wasn’t persevering with to come back off—and it could have been beginning to come again on.

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

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

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


I see some potential downsides, nonetheless.

Potential Downsides of GLP-1 Agonists

  • You most likely need to take it for all times. A current paper adopted a gaggle of people that had taken semaglutide for over a yr and misplaced a number of 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 many of the weight off. Those that went off the drug shortly regained many of the weight and misplaced nearly the entire different well being advantages (blood sugar, blood lipids, blood strain, and so forth.).
  • It’s costly. At the least as of now, the month-to-month value of a GLP-1 agonist subscription is $1500. Insurance coverage could cowl a lot of that, however it’s important to be severely chubby or wait til these medicine are prescribed for delicate chubby—however even then, assuming you have got insurance coverage, somebody’s paying.
  • Liraglutide has been proven to extend adipogenesis, the creation of latest fats cells, no less than in mice. Even because the rodents misplaced weight, they elevated the variety of fats cells of their physique. This can be a course of that usually happens in childhood. It’s one motive why childhood weight problems is so onerous to beat and so usually results in grownup weight problems. You could have a ton of “further” 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 enhance the creation of latest fats cells, what occurs once you cease taking it? What occurs in 5 or ten years? Do these “empty” fats cells shortly refill? It’s an fascinating query we merely don’t know the reply to. But.
  • GLP-1 agonists enhance resting coronary heart fee, with the longer-lasting variations like injectable semaglutide (the most typical used for weight reduction) resulting in sustained and long-lasting rises in resting coronary heart fee. Whether or not this portends a rise in well being points down the highway stays to be seen, but it surely’s typically accepted {that a} larger resting coronary heart fee is a foul factor.
  • GLP-1 agonists trigger nausea and diarrhea. They’re really the most typical unwanted side effects individuals complain about, they usually could even contribute to the disinterest in meals individuals report. It’s onerous 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 some pounds, however anecdotally, it doesn’t appear to occur when individuals shed some pounds following a Primal manner of consuming and exercising. This might doubtlessly be averted by merely emphasizing protein and ensuring to elevate heavy issues somewhat than counting on the semaglutide to do all of the work.
  • The advantages stage off after about 68 weeks. They could proceed in case you bump up the dose, however that will even enhance 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 medicine 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 important 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 chubby into true leanness. To try this, you even have to deal with different facets of your food plan and life-style to actually make the adjustments stick and prolong them into perpetuity.

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

In the end, most individuals studying this don’t want semaglutide injections. You’re already keen to do the work and make everlasting adjustments to your food plan, life-style, 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 medicine—in any case, I strongly suspect there’s no free lunch with regards to stuff like this—they might be helpful on internet to individuals who’d in any other case by no means contemplate altering their food plan and life-style.
