Preliminary analysis means that individuals who attain a wholesome weight and enhance their metabolic well being whereas taking GLP-1 medication could possibly preserve these features even once they change from weekly to biweekly and scale back their dosage.
These findings might have main real-world implications, stated lead writer Mitch Biermann, M.D., a bariatric and inner drugs specialist at Scripps Clinic Carmel Valley in California.
“The primary concern I obtain from sufferers who’re hesitant to start out remedy is that there isn’t a method to decelerate remedy as soon as they’ve misplaced weight. This knowledge supplies an instance of an method that’s typically extremely profitable and will inspire folks to start out remedy within the first place,” says Dr. Biermann.
Greater than 3 out of 4 folks maintained upkeep weight after switching to once-every-2-week injections
The examine was a retrospective chart evaluate, that means the researchers checked out medical data retrospectively reasonably than enrolling contributors in a randomized managed trial. This examine was small. The examine included simply 30 sufferers in a main care bariatric clinic who had achieved regular weight or resolved a weight-related well being situation after receiving weekly GLP-1 remedy (on this case, both Ozempic (semaglutide) or Zepbound (tirzepatide)).
Most individuals had been taking lower than the utmost advisable dose on a weekly schedule for 38 weeks earlier than switching to biweekly. When given usually, they misplaced a median of about 15% of their physique weight. Common BMI decreased from 29.5 to 24.5.
Key findings from the evaluation embody:
- Physique weight and fat-to-muscle ratio remained roughly the identical. After switching to biweekly injections, I misplaced a further 2 to 4 kilos on common, and my physique fats loss improved barely, however remained about the identical.
- Metabolic well being remained secure. Enhancements in glycemic management, triglycerides, and systolic blood strain remained related after dose discount.
- Most contributors continued to drop some weight. Solely 4 of 30 folks regained weight and selected to return to weekly dosing.
The remaining 26 sufferers continued to take care of their outcomes with a diminished dose, though some selected to increase their dosing schedule by two weeks or extra.
In actual fact, some docs are already serving to sufferers taper their GLP-1 doses.
Like many well being care suppliers who prescribe GLP-1, Yuval Pinto, MD, steadily reduces the frequency of dosing for sufferers who need to strive it.
“It may be efficient, and the examine outcomes offered listed here are promising,” says Dr. Pinto, a doctor in weight problems and household drugs at Johns Hopkins College of Drugs in Baltimore, who was not concerned within the examine. “Nonetheless, this examine concerned a small variety of folks and the outcomes had been obtained from a retrospective chart evaluate reasonably than a randomized examine, so they need to be considered as preliminary.”
Pinto says there are lots of elements that have an effect on weight. Taking medicines similar to GLP-1 is one instance, however different medicines, circumstances similar to sleep apnea, and weight-reduction plan and train may trigger adjustments. He factors out that the examine didn’t take these elements into consideration.
Dr. Peminda Kabandugama, an endocrinologist and weight problems drugs skilled on the Cleveland Clinic in Ohio, stated the discovering that most individuals had been in a position to preserve their weight was “somewhat shocking.”
“The pharmacokinetics (how the drug strikes by the physique) of GLP-1 medication point out that they’ve a half-life of 5 days, which signifies that the present commonplace of utilizing these medication each seven days additionally extends this,” says Dr. Kabandugama, who was not concerned within the examine. Half-life is the time it takes for the preliminary focus of a drug within the physique to lower by half.
The findings might also be influenced by the small quantity of people that participated within the examine, he added.
“Whether or not individuals are profitable in relieving signs could also be associated partly to how the drug is metabolized and the size of its ‘regular state,'” Pinto says. This varies from individual to individual relying on age and liver and kidney operate.
Giant-scale analysis is required
There are a “very small share” of people that do not regain the load they misplaced even after they cease taking GLP-1, however they’re the exception, Pinto says.
If these new findings are confirmed in bigger research, he theorizes, they might assist some folks take GLP-1 for longer and preserve a wholesome weight if they’ll proceed the costly routine for longer.
“The consensus amongst all medical societies is that it’s good to take these medication indefinitely, however in actual life that is not an possibility for most individuals. Sooner or later, your insurance coverage will cease taking them,” he says.
“The typical size of time an individual takes GLP-1 in america is one yr and two months,” he says.
Life-style elements similar to train might assist scale back drug doses
You may most successfully preserve your weight reduction efforts in case you train steadily, Biermann says.
“Now we have a nationwide survey known as the Nationwide Weight Administration Registry of people that have been shedding pounds for a few years. The typical quantity of train for folks in that group is one hour per day,” he says.
“Some sufferers use their medicines even much less typically than as soon as each two weeks, however they uniformly say they train quite a bit,” Biermann says.

All consultants agree that if you wish to change your GLP-1 dose or frequency, it is best to first speak to your well being care supplier.
“There is no such thing as a commonplace of look after learn how to de-escalate remedy, so completely different docs have completely different experiences and practices,” Biermann says.
In case you’re taking GLP-1 and need to regulate your dose for monetary causes, a change in insurance coverage protection, or since you not need to take the drug, it is best to speak to your physician about the perfect path ahead, Pinto says.
Mr. Pinto may be very open to conversations with sufferers who ask about discontinuing GLP-1 or spacing out doses. “Affected person-centered care is the perfect care,” he says.
First, he evaluations with sufferers what their objectives are and what they’ve achieved thus far. “Let’s examine if we have improved your prediabetes. Has your fatty liver, sleep high quality, train, and weight-reduction plan improved?”
So long as a affected person’s metabolic profile improves and so they attain a wholesome weight, “I am superb,” Pinto says. He’ll proceed to watch their weight and muscle mass as soon as a brand new dosing schedule is agreed.
“Would not it’s shocking if after a couple of months a affected person features muscle mass however their weight stays the identical? If the load rebounds, you are in hassle, as a result of you are going to find yourself with the identical drawback you began with,” says Pinto. Working along with your supplier might help you progress in the correct course, he says.
