What Is Tirzepatide? 

In a report published in November 2023, the U.S. Food and Drug Administration or FDA approved Zepbound, also known as tirzepatide, for chronic weight management in adults. This medicine can only be used by adults suffering from obesity or who are overweight. 

The ideal candidates for tirzepatide must have a body mass of:

  • 30 kg/m2 or more

  • 27 kg/m2 or more with at least one weight-related condition

Tirzepatide was initially developed to treat type 2 diabetes but became an effective solution for weight loss. The name of the brand for tirzepatide that solely works for diabetes is Ozempic. It shouldn't be confused with Zepbound which is just for obesity. 

Tirzepatide is used as a weekly injection, which is supposed to be administered for a long time to kick off its outcome. 

In some cases, intake may stretch to a lifetime. Your consultant might be the right person to tell you the intake duration. That's because, according to certain studies, some people who stop taking tirzepatide suddenly, easily regain all the weight loss. 

How Effective Is Tirzepatide for Weight Loss? 

Tirzepatide can be effective for tirzepatide if you make significant life changes along with its consumption. It includes following a healthy, calorie deficit diet and a proper workout routine.

In a study, 300 participants took tirzepatide for around 88 weeks. They experienced a mean weight reduction of 25.3% during this tenure. This decrease was far more than those who took a placebo.  

One random trial posted on The New England Journal of Medicine, people who took high doses of tirzepatide saw a 21.4% decrease in their weight within a year. 

It’s important to note that all the participants that took part in the above trials went on a calories-deficit diet and were also asked to workout regularly. So, tirzepatide alone won’t make you slim; it can only aid your weight loss efforts.

How Does Tirzepatide Work for Weight Loss? 

Now that you understand tirzepatide’s effectiveness for weight loss, let's dig deep to find how it achieves it all. 

Tirzepatide for weight loss works by reducing your appetite and prolonging your feeling of fullness. As a result, you consume fewer calories in a day. 

Unlike other weight loss medications, tirzepatide is a combination of two categories: a glucagon-like peptide-1 (GLP-1) receptor agonist and a glucose-dependent insulinotropic polypeptide (GIP) receptor agonist. Therefore, it is called the dual GLP-1/GIP receptor agonist. 

Tirzepatide for weight loss works by mimicking two hormones, GIP and GLP-1. These are incretin hormones that push the pancreas to release insulin while signaling the liver to reduce the amount of glucose it is making. As a result, the blood glucose levels decrease. 

In addition to this, tirzepatide signals your brain about your full stomach. This makes you eat less. 

This medication also slows down the movement of food in your stomach, allowing you to stay full for a long time.

Does Tirzepatide Work for Weight Loss Quickly?

You may be wondering how quickly this substance can change your life. Well, everyone's timeline for tirzepatide is different. How quickly you lose weight depends on several factors, such as your diet, age, activity levels, and habits. 

That said, some people who practice a strict diet and a workout routine start losing weight within a month or two of taking tirzepatide. Regardless of when you start seeing a difference in your weight, tirzepatide works best when taken for a long time. 

In most studies conducted on tirzepatide’s effectiveness for weight loss, participants were administered the drug for 72 weeks or more. That's because weight loss programs like these should always be based on long-term results rather than quick outcomes. 

Who Should Use Tirzepatide? 

As stated earlier, tirzepatide injection is for anyone who is obese or overweight and is seeking weight management. Tirzepatide, when combined with a good diet and exercise, ensures gradual weight loss. 

Who Shouldn't Use Tirzepatide? 

Here is a list of people who shouldn't take tirzepatide. 

  • Anyone who is not obese or overweight

  • People with kidney issues

  • Anyone who takes nonprescription medicines such as aspirin

  • People who take medicines for appetite control, asthma, hay fever, colds, cough, or sinus issues

  • Users who can’t stop their alcohol consumption

The recommended maintenance dosages are 5 mg, 10 mg, or 15 mg SC per week.
