Factors That Affect the Outcomes of Weight Loss

Take Your Dosage Consistently Every Day

Saxenda is a medication that is to be taken once every day. Giving yourself the injection around the same time every day is important. Choose a time that is convenient for you, and you can remind yourself to take your medication. Stick to a schedule that suits you. It does not matter if you take your Saxenda before or after a meal. 

Give the Medication Time to Work

Initially, the dosage of the medication is less, and it gradually increases over time, so the drug takes time to show the desired result of weight loss. Give time for your body to adjust to the medication, and don’t rush the process, as it may cause more harm than good. You shouldn’t expect instant results with such medicines.

Follow a Nutritious, Low-Calorie Diet

Saxenda is used to working alongside a low-calorie diet to give the best results. You can discuss the best diet plan with your nutritionist. And follow the appropriate no. of calories that you should aim for to lose weight and keep it off. Keeping track of your calorie intake and meals will help you achieve your goals. 

Follow a Regular Exercise Routine

Before starting any physical activity or exercise, discuss with your care provider to find the exercises that work best for you.

How Long Does It Take to Lose Weight Using Saxenda?

Losing weight using Saxenda can take several weeks as when you initially start taking the medications, the dosage is less, and it will gradually increase over time. This is to help you avoid side effects like nausea, diarrhea, vomiting, and constipation. Once you reach the dosage of 3mg/ daily, then the impact of the medication will reach its full potential, and the weight loss will increase. Some people start losing weight within two to four weeks of starting the medication and lose 2-4% of their weight. 

Clinical trials found that some individuals lost up to 5% of their weight after eight weeks of treatment. After using Saxenda for one year, some people lost 9.2% or 21 pounds, an incredibly significant weight loss. But always remember that different people have different results with Saxenda. The weight loss or any side effects associated with the medication will depend on your experience. 

When you talk to your care provider at the 16-week appointment, they will inquire whether Saxenda is helping you in your weight loss journey. If you have yet to lose 4% of your initial body weight, you will be asked to stop it. Sometimes, even when the person does everything right, he still cannot lose weight; then it means that their body is not responding to Saxenda, and you should try another approach for losing weight. Keep in mind that everyone’s experience with the medication will be different.
