How much weight can you lose on Ozempic?


Ozempic or semaglutide (generic name) is a once weekly injection for the treatment of type 2 diabetes. It is used along with diet, exercise and other medications to control blood sugar levels in patients with type 2 diabetes.

How does it work? Ozempic for weight loss and blood sugar control

Ozempic belongs to a class of medications called glucagon-like peptide-1 (GLP-1) agonists. It works by signalling the body to produce more insulin when the blood sugar level is high. It is thought to help with weight loss by slowing down the emptying of the stomach, thus making you feel full quicker. Furthermore, it also acts in areas of the brain that regulate appetite and food intake. Together, these functions can help you feel less hungry, causing you to eat less food and lose more weight. If you don’t like taking an injection, Rybelsus (oral semaglutide) may be an option for you.

Evidence for Weight loss for Ozempic during clinical trial

Ozempic had multiple clinical trials across multiple countries involving thousands of patients. I will summarize the weight loss in each trial below along with a link to the published article if you are interested in reading up on more details. Note: I’m just listing the mean absolute weight loss that was reported in the patients that were taking Ozempic, check out the trial to see how it compares to the placebo or comparison group.

In Sustain 1 trial at week 30, patients that were taking 0.5 mg of ozempic weekly had an average weight loss of 8.22 lbs (3.73 kg) and patients that were taking 1 mg of ozempic weekly had an average weight loss of 9.98 lbs (4.53 kg).

In Sustain 2 trial at week 56, patients that were taking 0.5 mg of ozempic weekly had an average weight loss of 9.48 lbs (4.3 kg) and patients that were taking 1 mg of ozempic weekly had an average weight loss of 13.44 lbs (6.1 kg).

In Sustain 3 trial at week 56, patients that were taking 1 mg of ozempic weekly had an average weight loss of 12.34 lbs (5.6 kg).

In Sustain 4 trial at week 30, patients that were taking 0.5 mg of ozempic weekly had an average weight loss of 7.65 lbs (3.47 kg) and patients that were taking 1 mg of ozempic weekly had an average weight loss of 11.40 lbs (5.17 kg).

In Sustain 7 trial at week 40, patients that were taking 0.5 mg of ozempic weekly had an average weight loss of 10.14 lbs (4.6 kg) and patients that were taking 1 mg of ozempic weekly had an average weight loss of 14.33 lbs (6.5 kg)

In conclusion, the studies showed that you can lose a significant amount of weight on Ozempic while improving your blood sugar control. Higher dose of Ozempic was associated with greater weight loss. On average, in the first 6 months to a year, the clinical trials have shown that you can lose 7-10 lbs on ozempic 0.5 mg weekly dose and 10-14 lbs on ozempic 1 mg weekly dose.

Ozempic lowers the risk of heart attack and stroke

Patients with type 2 diabetes are at higher risk of heart attack, stroke and kidney disease. Taking ozempic has been shown to lower the risk of heart attack, stroke and death in adults with diabetes and known heart disease. It may also reduce the risk of new kidney disease or slow down the worsening of kidney disease.

Ozempic dose

Initially, you will be started on ozempic 0.25 mg subcutaneous injection once a week for 4 weeks and then increased to 0.5 mg one weekly. After a further 4 weeks on 0.5 mg weekly dose, it can be increased to 1 mg once weekly to get better blood sugar control if needed. You are started on a lower dose and increased slowly to help reduce side effects and make ozempic more tolerable. You should take ozempic as prescribed by your doctor.

How much weight can you lose in a month with ozempic?
It is hard to predict how much weight you can lose in a month while on ozempic. Most of the trials used a longer time-frame of several months and higher doses were associated with more weight loss. Since you start at a lower dose and then titrate up, you might not see significant weight loss in the first month but if you stick with it, studies shows that you are likely to achieve weight loss.
