What is Mounjaro?
Mounjaro is a medicine that not only regulates blood sugar level but also works very well for weight loss. Dr Sarah Fishman explains the scientific reasons behind this. He is an experienced endocrinologist at Northwell Health’s Lenox Hill Hospital in New York. According to him, Monzaro works as a GLP-1 and GIP receptor agonist. These two mainly mimic the action of hormones called incretins. Their job is to control the amount of sugar in the blood.
Some pharmaceutical experts now think otherwise. Intellihealth, a company associated with excess fat loss treatment, has its Chief Medical Officer Dr. Leon I. Eagle. He is a fat loss drug specialist and endocrinologist. He revealed that some healthcare companies are using Mounjaro for weight loss despite not having FDA approval.
In 2022, a medical trial used Mounjaro in some people without diabetes to reduce excess weight. Participants were injected with Mounjaro at different doses every week such as 5 mg, 10 mg, 15 mg. Very surprising results were obtained. Those given the 5 mg dose lost 15%, those given the 10 mg dose lost 19.5%, and those given the 15 mg dose lost 20.9%.
Another study in 2023 found that Mounjaro worked very well for weight loss in obese people with type 2 diabetes.
How does Mounjaro work?
Mounjaro works a little differently than Ozmpic and Wegovir. It does not stimulate only one receptor, but acts on two receptors simultaneously, so it is called a ‘dual-agonist’.
Dual agonists are more effective than single-agonists for weight loss. These receptors are glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). When these receptors are activated, they control the amount of gloucse in the blood as well as reduce hunger, resulting in weight loss.
Ozempic and Wegovi activate only GLP-1 receptors but Mounjaro activates both GLP-1 and GIP receptors simultaneously.
Mounjaro can be taken weekly under the skin. It is available in single dose pen. Injections can be taken under the skin in the abdomen, thighs, and it is very important to change the injection site every time. 2.5 mg dose can be started initially and then the dose can be increased by 2.5 mg every four weeks till the appropriate dose is reached.
Dr. Fishman says the effective dose for weight loss depends on the individual. Some people get good results with a small dose like 2.5 mg or 5 mg, some with a medium dose like 7.5 mg or 10 mg, some use up to 12.5 mg or 15 mg.
A missed dose of it can be taken within the next 4 days or 96 hours. If it is more than four days then this dose should be taken on the specified day. Two doses of Mounjaro should not be taken three days apart.
How much weight do people lose with Mounjaro?
Clinical trials of Mounjaro have yielded very surprising results. Those given the 15 mg dose lost up to 21% in weight.

How to use Mounjaro for weight loss?
It is injected under the skin in the same way that Mounjaro is used for type 2 diabetes, for weight loss. The only difference is the dose and how many days it is used.
If using this medicine for weight loss or any other reason, it should start with the lowest dose of 2.5 mg. After four weeks, the dose can be increased up to a maximum of 15 mg on the doctor’s advice. It is better to follow the doctor’s advice in this regard.
A small dose of Mounjaro is taken initially just to allow the body to adapt to a new drug. Not much weight loss may occur at this dose. Not everyone needs to go up to the highest dose. Many people lose up to 5% weight on 5 mg. Clinical trials have shown weight loss of up to 15% at the highest dose, and some patients outside of the trial have lost up to 22% at the same dose.
