Ozempic and others in a brand new class of weight-loss medicine have been known as “the medical sensation of the last decade.” Are they worthy of all of the hype?
For a deep dive, please see my primer on this subject. OZEMPIC: Dangers, Advantages, and Pure Options to GLP-1 Weight-Loss Medicine is out there as an e book, audiobook, and paperback. You can too view my video collection free of charge on the Ozempic subject web page or our YouTube channel. Listed here are among the key takeaways.
What Is GLP-1?
A naturally occurring hormone in our physique, glucagon-like peptide-1 (GLP-1) performs a task in regulating our blood sugar, urge for food, and digestion. Our gastrointestinal tract releases greater than 20 totally different peptide hormones, together with GLP-1. The first stimuli for secreting GLP-1 are meals wealthy in fat and carbohydrates, and GLP-1’s predominant motion is to sign satiety to the mind. It additionally slows our digestion. Delaying the speed at which meals leaves our abdomen not solely helps us really feel fuller for longer, but in addition helps with our blood sugar management. When GLP-1 or an agonist (mimic) is dripped into folks’s veins, urge for food is lowered, resulting in markedly lowered meals consumption—a lower in caloric consumption by as a lot as 25 to 50 %.
About GLP-1 Medicine
Our GLP-1 hormone acts as an urge for food suppressant by focusing on components of the mind chargeable for starvation and cravings. GLP-1-secreting cells don’t solely line our intestines; they’re additionally in our brains. These new anti-obesity medicine are GLP-1 agonists, mimicking the hormone’s motion by binding to GLP-1 receptors.
Our physique breaks down GLP-1 so shortly that it hardly makes it even one time round our circulatory system, which is why we are able to’t simply take the hormone instantly. A compound was found—within the venomous saliva of a lizard known as the Gila monster—that mimics GLP-1 however is immune to breakdown. Utilizing that compound as a template, the primary GLP-1 agonist was created and authorised for the remedy of diabetes about 20 years in the past. As a substitute of most of it being cleared from the physique inside two and a half minutes, like native, pure GLP-1, a lot of the drug stays within the physique for 2 and a half hours. That also means twice-daily injections, although, so then got here liraglutide, which lasts all day.
What Is Ozempic?
Ultimately, semaglutide was developed and branded as Ozempic, which might be injected simply as soon as a week. Ozempic was authorised in 2017 to deal with diabetes. Inside a couple of years, a day by day oral model had been developed, once more for diabetes, however researchers operating these medical trials observed a shocking aspect impact: Individuals’s appetites diminished.
How Does Ozempic Work?
In a method, GLP-1 agonist medicine work like contraception tablets. The Tablet mimics placental hormones, thereby tricking our physique into considering we’re pregnant on a regular basis. Ozempic-type medicine mimic GLP-1, thereby tricking our physique into considering we’re consuming on a regular basis. That’s the way it dials down our starvation drive.
Ozempic for Weight Loss
Within the longest trial thus far, greater than 17,000 people have been randomized to injections of both high-dose semaglutide or placebo for 4 years. General, these on the drug misplaced 9 % extra physique weight than these within the placebo group, however all the burden was misplaced within the first 65 weeks. Though they continued to get injected each week for 3 extra years, they didn’t lose any extra weight over the next 143 weeks.
Weight reduction tends to plateau as a result of the identical quantity of effort to chop energy—whether or not by means of willpower, medicine, or surgical procedure—is met with rising resistance as ongoing weight reduction more and more prompts our suggestions management circuit, stimulating our urge for food. Within the case of the GLP-1 medicine, the burden loss brought on by the preliminary drop in urge for food is undercut by an obvious exponential enhance in caloric consumption as our physique ratchets up our starvation once more. Inside 12 months, this resistance, mixed with the decreased caloric wants from being lighter, matches the persistent effort to chop energy, and weight reduction plateaus. And, as quickly as we cease taking the medicine, our full urge for food resumes and we begin regaining the burden we initially misplaced.
The Price of Ozempic
Wegovy, the high-dose Ozempic used for weight reduction, prices as much as $1,350 a month, which, once more, could need to be paid in perpetuity since any misplaced weight can pile again on should you cease taking it. So, that would value greater than $16,000 a yr if paid out-of-pocket for these whose insurance coverage doesn’t cowl it.
Ozempic Facet Results
Probably the most widespread negative effects embrace nausea, vomiting, diarrhea, and constipation. Gallbladder points are one other aspect impact; extra ldl cholesterol shed from fats cells can crystalize in our bile like rock sweet, forming gallstones.
Uncommon however critical opposed results are additionally rising. The bundle inserts for each semaglutide and tirzepatide record a collection of “warnings and precautions” that embrace thyroid tumors, acute irritation of the pancreas (pancreatitis), acute gallbladder illness, acute kidney damage (which will stem from dehydration resulting from extra vomiting or diarrhea), allergic reactions, a heightened threat of bottoming out blood sugars whereas on blood sugar–decreasing drugs, worsening eye illness for these with kind 2 diabetes, a rise in coronary heart fee requiring monitoring, and suicidal ideas and behaviors.
What Is “Ozempic Face”?
“Ozempic face” is a time period used to explain a distorted facial look amongst customers of the drug. (Related accounts have been made from “Ozempic butt.”) Media reviews have linked the drug with facial ageing, however the sagging look has been ascribed merely to the accelerated lack of fats within the face. Whereas this interpretation appears logical, a assessment of the phenomenon concluded that “this rationalization can not totally account for the markedly accelerated facial ageing….” Different components suspected as being chargeable for the looks of untimely facial ageing embrace the lack of facial muscle mass, diminished structural integrity of the pores and skin, and modifications in stem cell operate and hormonal secretion.
Is Ozempic Secure?
Within the first quantitative benefit-versus-harm steadiness evaluation, the researchers concluded that these attaining a ten % weight reduction had a greater than 90 % likelihood that the advantages of taking the medicine outweigh the harms, however the reverse was discovered for people attaining solely a 5 % weight reduction.
Right now, we don’t know concerning the long-term harms or advantages as a result of a few of these medicine and dosing schedules are so new. To complicate issues, the American Academy of Pediatrics has advised providing these medicine for teenagers and even tweens as younger as age 12. These medicine work by appearing on the mind, so who is aware of what impact they could have on childhood growth and past if younger folks find yourself taking them for the remainder of their lives. Though we now have proof of close to-term profit over a couple of years, we can not assume long-term security till it has been demonstrated.
Ozempic Options
We don’t have to take GLP-1-mimicking medicine. Not solely can the ingestion of a plant-based meal greater than double GLP-1 secretion, in comparison with a meat meal, however plant-based diets may also trigger weight reduction by boosting our resting metabolic fee and incorporating “calorie-trapping” high-fiber meals that flush energy away. The most important examine of individuals consuming strictly plant-based discovered they’re about 35 kilos lighter on common.
After we eat a donut, its fats, sugar, and starch get absorbed shortly, excessive up, earlier than reaching the a part of our digestive tract the place we produce many of the hormone that suppresses our urge for food, GLP-1. For the reason that cells that produce GLP-1 in response to calorie publicity are concentrated on the finish of our digestive tract, whereas the vast majority of the energy we eat are absorbed early on, most energy by no means make it down far sufficient. That’s why our appetites aren’t suppressed very a lot lately. From a GLP-1 standpoint, when now we have that donut, it’s like we by no means ate a lot of something. No marvel we attain for donut quantity two.
Our prehistoric ancestors are believed to have consumed as a lot as 100 day by day grams of fiber, which is greater than six instances what most of us are getting lately. We developed consuming large quantities of entire plant meals—the one locations fiber is present in abundance. That enabled out pure satiety mechanisms to maintain us from overeating. By consuming the best way nature meant, we are able to launch GLP-1 the best way nature meant. That helps explains why within the medical literature, in comparison with every other method of consuming that didn’t contain portion management, an entire meals, plant-based weight loss program has been proven to result in higher common weight reduction than every other weight loss program.
