All In regards to the New Weight Loss Medication


Man sitting in front of coffee table preparing Semaglutide Ozempic injection.America 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 methods. The parts are monumental. 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 crucial meals our ancestors developed consuming: animal protein. The most cost effective meals is the worst and the healthiest is the costliest.

It’s a giant mess, and many individuals resist the dietary and way of life modifications required to repair the difficulty. It’s no marvel many individuals have been hoping for a capsule or treatment that fixes the weight problems drawback. 

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 vogue fashions are taking these medication in huge portions. Silicon Valley tech circles are taking them—Elon Musk, most famously, is on semaglutide. In brief, virtually 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 chubby sufferers.

Initially designed as diabetes medication, these brokers mimic the results of glucagon-like peptide-1, an incretin hormone the physique releases if 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, conserving you full for longer. 

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

  • Decrease glucose manufacturing
  • Extra glucose uptake by muscle mass
  • Elevated insulin sensitivity 
  • Decrease blood strain
  • 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 losing a few pounds?

Sure. They work. Out of all the burden loss medication the trade has pushed and examined and tried, the GLP-1 agonists really assist individuals drop some weight.

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 had been girls. One group obtained the drug, the opposite obtained placebo. Each teams had 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 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 had been nonetheless chubby or overweight. 15 p.c of 233 kilos is about 35 kilos. That’s an incredible 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 gaggle), and so they even began to barely acquire by the top of the examine. It was a really minor uptick, however an uptick nonetheless.

Semaglutide wasn’t sufficient for them. They had been nonetheless principally chubby, and the burden wasn’t persevering with to come back 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:

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

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


I see some potential downsides, nevertheless.

Potential Downsides of GLP-1 Agonists

  • You in all probability should take it for all times. A current paper adopted a gaggle of people that had taken semaglutide for over a 12 months and misplaced lots 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 had been nonetheless on the sauce stored many of the weight off. Those that went off the drug rapidly regained many of the weight and misplaced virtually all the 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 price of a GLP-1 agonist subscription is $1500. Insurance coverage might cowl a lot of that, however it’s a must to be severely chubby or wait til these medication are prescribed for delicate chubby—however even then, assuming you’ve gotten insurance coverage, somebody’s paying.
  • Liraglutide has been proven to extend adipogenesis, the creation of latest fats cells, at the least 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 cause why childhood weight problems is so onerous to beat and so usually results in grownup weight problems. You may have a ton of “additional” fats cells from if you had 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 if you cease taking it? What occurs in 5 or ten years? Do these “empty” fats cells rapidly replenish? It’s an attention-grabbing 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} increased resting coronary heart fee is a nasty factor.
  • GLP-1 agonists trigger nausea and diarrhea. They’re really the most typical unwanted effects individuals complain about, and so they might even contribute to the disinterest in meals individuals report. It’s onerous to be hungry if 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 drop some weight, however anecdotally, it doesn’t appear to occur when individuals drop some weight following a Primal method of consuming and exercising. This might doubtlessly be prevented by merely emphasizing protein and ensuring to raise heavy issues slightly than counting on the semaglutide to do all of the work.
  • The advantages stage off after about 68 weeks. They could proceed if you happen to bump up the dose, however that may also enhance the possibility of unwanted 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) knowledge.

My Closing 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 chubby into true leanness. To do this, you even have to handle different features of your weight loss program and way of life to essentially make the modifications stick and prolong them into perpetuity.

I do suppose it may assist individuals stick with a greater weight loss program. Whereas the fanfare focuses on the truth that you may “eat no matter you need” and nonetheless drop some weight, it’s additionally been proven to scale back cravings for junk meals and starches. A sensible use of this drug could be to pair it with a wholesome low-carb weight loss program 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 enough 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 modifications to your weight loss program, way of life, and train habits that set you up for long run success. However hundreds of thousands of individuals aren’t. Whereas I’ve some main reservations about the long run results of those medication—in spite of everything, I strongly suspect there’s no free lunch relating to stuff like this—they could be helpful on internet to individuals who’d in any other case by no means contemplate altering their weight loss program and way of life.
