This is especially important for individuals with type 2 diabetes who are looking to manage blood sugar levels and promote weight loss.
Both medications are designed to treat type 2 diabetes, but they’ve different mechanisms of action.
Rybelsus slows down gastric emptying, controls appetite, and promotes weight reduction, whereas metformin stimulates insulin sensitivity and controls glucose production in the liver, also contributing to weight loss.
However, clinical trials have shown that Rybelsus induces substantially greater weight loss than metformin, with a mean body weight reduction of -14.9% from baseline compared to -5.8% for metformin.
In a 68-week trial, Rybelsus resulted in a notably greater proportion of patients achieving ≤5% and ≤10% weight loss compared to metformin.
Dosing and Administration
To effectively manage your type 2 diabetes and weight loss path, you’ll need to understand the dosing and administration of both Rybelsus and metformin.
Regarding Rybelsus, the recommended starting dosage is 3 mg once daily, which can be increased to 7 mg or 14 mg once daily if necessary and tolerated. You’ll need to take Rybelsus orally, with 4 ounces of plain water, and swallow the tablet whole.

Real-World Experience and Results
You’ve probably wondered which medication yields the most impressive weight loss results in real-world scenarios, and the data is convincing: Rybelsus consistently outperforms metformin in respect to both the magnitude and percentage of weight loss.
In a 68-week trial, Rybelsus resulted in a mean weight loss of 12.3 kg (9.4% of body weight) compared to 2.6 kg (2.1% of body weight) with metformin. That’s a significant difference!
Semaglutide 2.4 mg was found to have induced an overall mean body weight reduction of 14.9% for patients without diabetes in the STEP 1 trial and 9.6% for patients with diabetes in the STEP 2 trial at 68 weeks 16 , 23 The present study had slightly higher proportions of patients who were female, overweight, had class 3 obesity, or who had baseline comorbidities of hypertension, dyslipidemia, and obstructive sleep apnea compared to the STEP 1 trial. 16 Moreover, individuals with type 2 diabetes, who have been shown to experience less weight reduction than those without diabetes, were not excluded from the analysis. Nevertheless, the body weight outcomes from this real‐world study align with the results from the STEP 1 trial at a comparable time point.
In this study, a total of 961 patients with type 2 diabetes found that Rybelsus led to a greater percentage of patients achieving ≥5% weight loss (63.2% vs 23.1% with metformin).
What does this mean for you? If you’re struggling to manage blood sugar levels and lose weight, Rybelsus might be a better fit for your treatment plan.
It’s essential to discuss your options with your healthcare provider, since both medications come with serious side effects. However, if weight loss is a top priority, Rybelsus seems to be the clear winner.
