More than two in five adults in the U.S. are living with obesity, according to a 2024 report. Some of us in this group know what it is like to feel stuck in a cycle of dieting, losing, and gaining it all back. 

You watch the scale move up, your energy drops, and your health risks rise, and nothing seems to work long-term.

That’s why many people ask about the best weight loss injection. At Oak Longevity, we offer science-backed treatments that support real, steady weight loss. 

In this guide, we’ll explain the top options and how they work, so you can finally see a realistic and sustainable path forward.

Popular Weight Loss Injections Explained

There are a few popular weight loss injection options that doctors discuss today. You’ve probably heard of some of them:

• Ozempic for Weight Loss (Semaglutide): Ozempic is approved to treat type 2 diabetes, but its active ingredient, semaglutide, can also help with weight loss when prescribed under medical supervision.
• Wegovy (Semaglutide): This drug has the same active ingredient as Ozempic but at a dose approved for weight loss. It helps people with obesity or those who are overweight with a related health condition lose weight and keep it off.
• Mounjaro (Tirzepatide): This weekly injection works by affecting two natural hormones in your body, GLP-1 and GIP. It can lead to significant weight loss for many people. While Mounjaro is approved for type 2 diabetes, doctors may prescribe it for weight loss.
• Zepbound (Tirzepatide): Zepbound contains the same active ingredient as Mounjaro but is specifically approved for chronic weight management. It is a weekly injection that targets GIP and GLP-1 pathways, helping reduce appetite and food intake.

How Do Weight Loss Injections Work?

Most leading weight loss injections belong to a group of medications known as GLP-1 receptor agonists. 

Think of GLP-1 as a natural hormone your body already makes. These medications copy their actions.

Here’s what GLP-1 medications do:

• Reduces Appetite
• Increases Fullness
• Slows Digestion

Mounjaro goes further by mimicking another hormone called GIP, which adds to these effects and potentially leads to even greater weight loss. 

Benefits and Risks of Weight Loss Injections

When considering weight loss injection options, it’s helpful to look at both the good and the challenging aspects.

Benefits:

• Significant Weight Loss: Many people see meaningful weight loss with these medications. Studies show that on average, a person loses 8% to 15% more weight with weight loss injections within 12 to 18 months than with diet, exercise, and oral medications alone.
• Improved Health Markers: Losing weight can lead to better blood sugar levels, lower blood pressure, and healthier cholesterol. 
• Support for Healthy Habits: These medications can help reduce constant food thoughts and cravings, making it easier to stick to your nutrition and activity plans.

Risks:

• Side Effects: Like all medications, GLP-1 and GIP/GLP-1 medications can have side effects. The most common ones are stomach-related, such as nausea, vomiting, diarrhea, or constipation. These often get better over time. 
• Not for Everyone: These medications are typically for adults with a certain BMI, or those who are overweight with a related health condition. They are not for cosmetic weight loss. 
• Ongoing Treatment: Many patients use these medications as a long-term treatment. You might regain some of your lost weight if you stop taking them.
