Ozempic and Mounjaro: The Weight Loss Benefits of GLP-1 Agonists

The GLP-1 agonist drugs, Ozempic and Mounjaro, have gained significant attention for their ability to not only treat diabetes but also cause significant and sustained weight loss. This remarkable effect can be attributed to their impact on incretin hormones, specifically glucagon-like peptide-1 (GLP-1).

GLP-1 is a hormone released by the intestine in response to food intake. It plays a crucial role in regulating blood sugar levels by stimulating insulin secretion and inhibiting glucagon release. Additionally, GLP-1 slows down gastric emptying, leading to increased satiety and reduced appetite.

Ozempic and Mounjaro are designed to mimic the actions of GLP-1. When these drugs are administered, they bind to GLP-1 receptors in different parts of the body, including the pancreas, brain, and stomach. By activating these receptors, they enhance the effects of GLP-1, resulting in several beneficial outcomes.

One of the primary effects is the promotion of insulin secretion from pancreatic beta cells. This leads to improved glucose uptake by cells and a decrease in blood sugar levels. Additionally, GLP-1 agonists suppress the release of glucagon, which is responsible for increasing blood sugar levels. By blunting glucagon’s action, these drugs help maintain a more stable glucose balance.

In regards to weight loss, GLP-1 agonists exert multiple effects. They delay gastric emptying, which means food stays in the stomach for a longer duration, creating a feeling of fullness and reducing the urge to eat. Moreover, GLP-1 agonists act on the hypothalamus in the brain, helping to regulate appetite and satiety signals.

Furthermore, GLP-1 agonists increase energy expenditure and promote fat burning. They enhance the breakdown of stored fat while simultaneously decreasing the absorption of fat from the gastrointestinal tract. These combined mechanisms contribute to substantial weight loss over time.

It is worth noting that the weight loss achieved with GLP-1 agonist drugs varies from person to person. However, studies have demonstrated that patients using Ozempic or Mounjaro experience more significant weight loss compared to other diabetes medications.

In conclusion, the GLP-1 agonist drugs, such as Ozempic and Mounjaro, are effective treatments for diabetes while also offering the substantial benefit of promoting significant and sustained weight loss. By influencing incretin hormones, these medications provide a comprehensive approach to managing both blood sugar levels and body weight.

Glucose-regulating medications used to treat type 2 diabetes have also been shown to have very positive effects on obesity

Glucose-regulating medications used to treat type 2 diabetes have also been shown to have very positive effects on obesity, which may alter how obesity is treated.

Anti-diabetic drugs with glucose-regulating effects have been shown to have a significant weight-reducing effect in obese patients, with tirzepatid providing a weight reduction of more than 20%, comparable to bariatric surgery.

Semaglutide had the same good effect in a study among teenagers 4 , and a similar study is underway regarding tirzepatid.

Semaglutide and tirzepatide are peptides in the incretin class that mimic intestinal hormones and stimulate insulin secretion. Semaglutide works by activating the GLP-1 receptor, while tirzepatid works by activating both the GLP-1 and GIP receptors. Clinical effects include increased satiety, delayed gastric emptying, increased insulin and insulin sensitivity, decreased glucagon, and lower blood glucose levels. Side effects include nausea, vomiting, abdominal pain, constipation, and diarrhea.

In a direct comparative randomized trial, tirzepatid outperformed semaglutide 7 in terms of glucose control. Both drugs had highly beneficial effects on lipids, resulting in lower triglycerides, lower LDL cholesterol, and higher HDL cholesterol, as well as lower blood pressure.

These drugs are very expensive and must be taken for 12–18 months before the full effect occurs. And if the patient is unable to change their lifestyle, it is likely that the weight will increase again when the drug treatment stops.


The global obesity epidemic has worsened, with 650 million obese adults and 340 million between the ages of 5 and 18. New drugs represent a breakthrough, providing weight reduction, cardiovascular risk factors, glucose regulation, reverse fatty liver, and reducing the effects obesity has on osteoarthritis and cancer.

The downsides are the price, the side effects, the fact that the drugs have to be given as injections, and the risk of relapse as soon as the treatment is over. 

Semaglutide is also available as a tablet, but this form is much less effective at helping people lose weight. But this means that in the future, it might be possible to make oral drugs that have the same effects. Several similar new drugs are in the works, which could lead to more competition and lower, more reasonable prices.

Why is losing weight so important for type 2 diabetes?

By losing weight, people with type 2 diabetes can feel better and, in some cases, even be cured. Those who are affected shouldn’t punish themselves by starving themselves or going on crash diets. Only a healthy diet helps in the long run. There are a few easy rules to follow.

Everyone needs sugar to get energy to their body cells. When we eat carbs, our bodies break them down into sugar in the gut and send it to the blood. When the amount of sugar in the blood rises, the body makes insulin. With the help of this hormone, sugar in the blood can be sent to the muscle cells or temporarily stored in the liver. Insulin works like a key: it lets the sugar into the cells.

This mechanism is broken for people with type 2 diabetes. The insulin no longer works right in the cells, so they use less sugar. ” Insulin resistance” is the term for this. Because of this, the blood sugar level goes up, and the pancreas makes more and more insulin. 

The problem is that insulin not only lowers blood sugar, but it also turns extra sugar into fat around the belly. In turn, having too much belly fat makes insulin resistance worse. Because fat cells release hormones that make muscle cells and the liver less sensitive to insulin. The good news is that if the fat in the belly is cut down, the cells can once again respond better to insulin.

Lose weight with the three-meal principle.

You don’t have to starve yourself or give up fun in order to lose weight. Most people can lose weight by eating three healthy meals a day and cutting back on snacks like cookies, chocolate, and chips that are high in sugar and calories.

Eating only three times a day has a big benefit: when you go longer without eating, your blood sugar level drops. Because of this, less insulin is made. Since insulin is a hormone that makes you gain fat, having low levels of insulin helps break down fat.

In theory, even two meals a day could be enough. Intermittent fasting is a way for people with type 2 diabetes to lose weight. For instance, you might skip breakfast or dinner and give your stomach 16 hours to rest. Recent studies have shown that intermittent fasting is a good way to lose weight and has many other health benefits as well.

But this way of fasting isn’t good for people who are more likely to get low blood sugar. This risk is especially high for people who inject insulin or take sulfonylurea pills. Before starting intermittent fasting, people with diabetes should talk to their doctor to see if there are any health risks.

Lots of vegetables, few carbs, good fat

Nutritionists recommend the plate principle, which states that half of a plate should be covered with vegetables, a quarter with protein-rich products, and a maximum of a quarter with carbohydrates. Bread is allowed, but only with one meal, in the form of high-fiber whole grain bread.

The most important details are that if you want to lose weight, you should eat 500 grams of vegetables every day, including herbs, nuts, and low-fructose fruit. Sugar should be avoided as much as possible, especially in sodas and sweet juices. Apple juice contains at least as much sugar as cola, and ready-made products from the supermarket contain added sugar.

Oil can be used without guilt, but it should be the right one. Omega-3 fatty acids, such as those from rapeseed, linseed, and nut oils, are particularly recommended. Olive oil also has positive effects on health, but sunflower oil contains omega-6 fatty acids. Oatmeal can be used to combat insulin resistance, with 75 g of oat flakes boiled in water three times a day and smaller amounts of fruit, herbs, and vegetables.

Weight loss in small increments

If you want to lose weight, it makes sense that you would want to do it quickly. But this is even harder for people with diabetes than for healthy people, especially if they inject insulin or take medicine that makes insulin come out of their bodies more quickly. Because insulin makes it hard to lose fat.

Experts warn against expecting too much at once, as long-established eating habits cannot be changed overnight. Crash diets are discouraged, as pounds that are lost quickly are usually put back on. Patient people will be rewarded if they succeed in improving their diet over time.

Can you cure type 2 diabetes by losing weight?

Type 2 diabetes can be reversed with weight loss, according to a 2017 British DiRECT study. Almost half of participants were able to reduce their diabetes within a year, with 86 percent for those who lost 30 pounds. However, the effect is only permanent if you maintain a healthy lifestyle.

What role does sport play in weight loss?

Sport is beneficial for people with type 2 diabetes, improving blood sugar, blood pressure and lipid levels. However, it does not help with weight loss, as physical exertion leads to more hunger and appetite hormones being released, leading to more eating.
