When attempting to reduce weight, we regularly make life-style adjustments, including train to a weight-reduction plan of extra fruit and veggies, lean proteins, and wholesome fat. We in the reduction of on quick meals and junk meals, all of the whereas dreading starvation pangs and that nagging voice, “Hey, I’m nonetheless hungry!”
What will we do? Typically we flip to higher-calorie meals that our our bodies can’t cease craving.
There are the explanation why our our bodies crave extra, acquire extra, and—strive as we’d—have hassle shedding and protecting weight off. The most typical causes are genetics, bodily or psychological sickness, and metabolism. You’ve in all probability heard about basal metabolic charge (BMR), which is the speed your physique burns energy whereas resting. Exams present that folks with a sooner metabolism naturally burn extra energy than folks with slower metabolic charges.

When energy aren’t all burned—or metabolized—our our bodies use a mechanism to retailer extra energy in cells. You see, our our bodies by no means know for certain when our subsequent meal will arrive. Sadly, when our our bodies sense an absence of meals (for instance, when weight-reduction plan or fasting), our metabolic charge slows. Clearly, that’s not what we’re searching for once we’re attempting to reduce weight.
The method of metabolism entails insulin, a naturally occurring hormone produced within the pancreas. After we eat energy, insulin directs the physique’s cells to absorb glucose from the bloodstream. As glucose strikes into our cells, blood glucose ranges decrease. This solves the issue of extended excessive blood glucose ranges which will trigger issues, like sort 2 diabetes.
It seems {that a} treatment known as semaglutide, a glucagon-like peptide (GLP-1) receptor agonist is perhaps our greatest weight-loss pal. Semaglutide will increase insulin secretion, which is nice for folks dwelling with sort 2 diabetes. It’s additionally good for people who find themselves chubby or overweight. Semaglutide additionally helps eradicate pangs of starvation that trigger us to overeat and snack.
The human physique has a objective to keep up homeostasis, all the time preventing to maintain its equilibrium. We train and lower high-calorie meals, however our our bodies inform us, “Wait, I don’t need to change!” So, we eat, after which we really feel unhealthy as a result of we will’t ignore meals cravings.
Don’t really feel unhealthy! It’s simply our physique’s mechanism working to keep up stability. Don’t worry, both. Worrying about cravings solely drags us down, including emotional pressure that may thwart our efforts to reduce weight.
We now know that semaglutide could assist.
In case you are dwelling with sort 2 diabetes, you would possibly already be taking a semaglutide treatment. If you don’t reside with sort 2 diabetes, semaglutide is now out there to fight weight reduction for some non-diabetic folks. This implies that you could be now use treatment to assist fight cravings in your struggle to reduce weight.
The Historical past of Semaglutide Historical past
A workforce of researchers working for the pharmaceutical firm Novo Nordisk first developed a semaglutide drug in 2012. The treatment, later named Ozempic, had beforehand run a sequence of scientific trials to check its efficacy—its desired outcomes—as a longer-acting different to liraglutide. Why? As a result of liraglutide wasn’t FDA accepted for the estimated 30 million folks dwelling with sort 2 diabetes whom researchers knew would profit from a longer-acting blood glucose management.
Liraglutide is a sort of treatment just like semaglutide, and each are GLP-1 receptor antagonists. GLP-1 receptor antagonists assist folks with sort 2 diabetes management their diabetes as a periodic remedy. Nevertheless, all new drugs should undergo scientific trials to substantiate efficacy earlier than getting FDA approval. This takes time.
One other Novo Nordisk scientific trial revealed that semaglutide may deal with sort 2-related weight problems by decreasing meals cravings and starvation. This semaglutide may additionally scale back physique fats. It was thrilling, prompting a second scientific trial, a part 3 randomized managed trial. This new trial discovered {that a} once-weekly injection, or 2.4 mg. of the drug, resulted in a mean discount of −14.9% physique weight at 68 weeks. In actual phrases, that’s like a 200-pound particular person shedding as much as 30 kilos!
With FDA approval in 2017, Novo Nordisk started advertising the treatment below the identify Ozempic.
Semaglutide Makes use of
Individuals who need assistance to manage their sort 2 diabetes with a semaglutide take both Ozempic, Wegovy, or Rybelsus. The medication supply some nice advantages. Along with weight reduction, the once-weekly self-administered shot may help scale back the dangers of sort 2 diabetes-related cardiovascular occasions and likewise keep decrease blood glucose ranges.
After all, there are different GLP-1 drugs, like Trulicity, however they don’t include semaglutide. Due to this fact, customers don’t expertise such excessive weight reduction outcomes.
How Semaglutide Drugs Assist Decrease Weight
Referred to as “incretin mimetics,” semaglutide mimics the hormone known as “glucagon-like peptide-1” (GLP-1). The GLP-1 hormone targets the areas of the mind that regulate meals consumption and urge for food. Some professionals name it a ‘starvation hormone’ as a result of the hormone makes us really feel full.
The pancreas performs an essential function in regulating how one other hormone, insulin, works. Keep in mind, homeostasis is the physique’s manner of sustaining equilibrium. After we eat a meal, we’re ingesting energy that increase our blood glucose (sugar). The pancreas in non-diabetic folks reacts by secreting insulin. Insulin helps keep a balanced blood glucose degree. Steadiness is homeostasis.
Take into consideration the way you ponder the prospect of consuming a favourite meals. You may’t wait. However at a sure level you start to really feel full. In truth, sooner or later, you’re so VERY full, you may’t eat yet another chew. Ugh!
That is homeostasis, because of insulin and the method of metabolism. It’s the physique’s manner of managing meals consumption in order that we don’t overeat.
How does a wholesome pancreas know that it must get to work? Amazingly, the gastrointestinal tract (intestine) responds to meals consumption by signaling to the pancreas, instructing it to start releasing insulin proper now. It’s known as the incretin impact.
When the gastrointestinal tract acknowledges glucose, incretins are despatched out to the pancreas. Instantly, the pancreas acknowledges the incretins and begins releasing (or holding onto) the correct amount of insulin wanted to match the glucose.
In different phrases, incretins stop us from growing hyperglycemia (excessive blood glucose). Now we perceive the pancreas’ response to consuming. However how does our intestine initially acknowledge caloric consumption?
The gut produces intestinal mucosa made up of two incretin peptides, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like peptide 1 (GLP-1). The incretin impact begins with these two peptides.
The physique’s peptides, although, react in a different way to blood glucose. GIP suppresses glucose secretion by managing the discharge of insulin as wanted (not an excessive amount of, not too little).
In the meantime, the GLP-1 receptor agonists transfer from the intestine to the pancreas to satisfy with and stimulate the GLP-1 receptors. The receptor agonists mainly say, “Maintain onto a few of that insulin for some time so we will take within the meals’s vitamins.”
Individuals with type-2 diabetes have GLP-1, however the incretin impact normally doesn’t work correctly. Their blood glucose will increase as a result of the pancreas doesn’t acknowledge GLP-1. Consider this communication disruption like your mobile phone whenever you’re on a mountain street: dropped calls occur.
What about individuals who don’t have diabetes? In non-diabetics, GLP-1 is well-connected; it all the time is aware of our blood glucose ranges. There aren’t any mountains interfering with communication.
GLP-1 additionally helps decelerate the method of emptying the abdomen. That is useful once we weight-reduction plan as a result of we really feel full longer. After we really feel full longer, then we don’t need additional snacks.
In response to a meal, the gastric inhibitory polypeptide (GIP) already started its work from the pancreas. When blood glucose ranges rise throughout and after consuming, GIP intensifies insulin launch each instantly and later—as wanted.

Incretin Impact: The intestine acknowledges meals and releases GLP-1 receptor agonists that meet up with the GLP-1 receptors within the pancreas. Now, glucose regulation begins as insulin strikes into the bloodstream to decrease blood glucose ranges whereas concurrently inhibiting glucagon (sugar) launch.
GIP, dwelling within the pancreas, helps regulate glucagon launch. In a well-working system, GIP is aware of when to carry on to glycogen, and when to launch glycogen.
Additionally in non-diabetics, GIP solely stimulates glucagon secretion at low glucose ranges, inflicting researchers to suggest that GIP has one other operate.
- First, GIP stabilizes blood glucose ranges by secreting glucose to manage hypoglycemia (low blood glucose).
- Concurrently, GIP additionally secretes insulin to decrease hyperglycemia (excessive blood glucose).
In different phrases, GIP is a really good stabilizer.
The FDA unanimously accepted semaglutide to be used by non-diabetic sufferers in 2021. Which means for those who don’t have diabetes, however you battle to manage weight, you might now additionally take semaglutide, administered by injection or orally.
You will want to satisfy the requirement for non-diabetics: these with a BMI of 30 kg/m2 or larger could now be prescribed semaglutide.
Conclusion
Semaglutide performs an advanced job involving the pancreas, intestine, mind, and extra. It’s a course of that makes us shake our heads and say, “No marvel dropping pounds is such a battle.” The physique isn’t simply good, it’s a tough employee, too, all the time striving to realize and keep homeostasis. This makes dropping pounds troublesome. It’s good to know you will have the facility of semaglutide in your facet.
