What Is The Best Injection For Weight Loss?

Welcome to our comprehensive guide on finding the best injection for weight loss! If you're on a journey to shed those extra kgs and considering injectable options, you're in the right place. In this blog, we'll delve into the world of weight loss injections.

What Are Weight Loss Injections?

Weight loss injections are a type of medical treatment designed to aid in weight loss efforts by administering specific compounds directly into the body through injections. These injections typically contain ingredients that are believed to boost metabolism, increase energy levels, promote fat burning, or suppress appetite.

As of April 2024, we have two weight loss injections in our pharmacy available through prescriptions through our medicated weight management serviceWegovy and Saxenda.

What is Wegovy?

Wegovy is a weight loss prescription medication. It's a once-weekly injection that works by mimicking a hormone called GLP-1, which helps to regulate hunger and appetite. Wegovy is approved for use in adults with a BMI of 27 or greater who also have a weight-related condition such as high blood pressure, high cholesterol, or type 2 diabetes.

We go through this more in depth in our Wegovy Weight Loss Page.

What is Saxenda?

Saxenda is another weight loss medication and like Wegovy, Saxenda also mimics the GLP-1 hormone to help reduce appetite and regulate blood sugar levels. Saxenda is approved for use in adults with a BMI of 30 or greater or in adults with a BMI of 27 or greater who have a weight-related condition.

What is the Best Injection For Weight Loss?

The best available weight-loss injection in the UK in 2023 was semaglutide (brand name Wegovy).

Research has shown that semaglutide 2.4 mg (Wegovy) can support weight loss of up to 20% after one year.

Should You Consider Weight Loss Injections?

While ideally, weight loss should be achieved through improved eating habits and lifestyle changes, for many individuals, the struggle with weight loss is complex and multi-faceted. In such cases, additional support may be necessary. GLP-1 medications, such as semaglutide, have been developed to provide this support.

By reducing hunger and the urge to overeat, these medications can empower individuals to make healthier choices and address the underlying factors contributing to their obesity. However, it's important to consult with a healthcare provider such as those at Kennedy's Pharmacy to determine if weight-loss injections are appropriate for your specific situation, as they may not be suitable for everyone.

Sustainable Weight Management Outside of Weight Loss Injections

While weight loss injections can be a helpful tool for some individuals struggling with obesity, it's crucial to recognize that they are just one component of a comprehensive weight loss approach. Sustainable weight loss is best achieved through a combination of healthy eating habits, regular physical activity, and lifestyle modifications.

It's important for users to understand that weight loss injections alone are not a magic solution and should be used in conjunction with other lifestyle changes. Developing long-term habits such as choosing nutrient-rich foods, practicing portion control, staying hydrated, getting enough sleep, and managing stress are essential for maintaining weight loss results over time.

Furthermore, seeking support from healthcare professionals, nutritionists, or dieticians can provide valuable guidance and accountability on your weight loss journey. By taking a holistic approach to weight loss and addressing underlying lifestyle factors, individuals can achieve lasting results and improve their overall health and well-being.


Are Wegovy and Saxenda safe to use?

Both medications have been approved by the FDA for use in adults with a BMI of 27 or greater. However, as with any medication, they come with potential side effects and should only be used under the guidance of a healthcare professional.

How long do I need to take Wegovy or Saxenda?

The length of treatment will depend on your weight loss goals and medical history. A qualified practitioner will determine how long you need to take the medication.

Can I take Wegovy or Saxenda if I'm pregnant or breastfeeding?

No, both medications are not recommended for use during pregnancy or breastfeeding.

Do I still need to diet and exercise while taking Wegovy or Saxenda?

Yes, weight loss medications should be used in conjunction with a healthy diet and regular exercise to achieve the best results.

Can Saxenda and Wegovy Be Used Together?

Liraglutide and semaglutide are not indicated for concurrent use. Since all GLP-1 medications have the same mechanism of action, they are not helpful when used concurrently. Talk to a healthcare provider for more information.
