Rybelsus not working: the numbers first
Rybelsus studies mainly focused on blood sugar. The weight studies shown here are from Wegovy, the same medicine at a higher dose.
| Trial | Dose group | Average weight lost | Placebo or comparison | Weeks | Who was in it |
|---|---|---|---|---|---|
| STEP 1 | Semaglutide 2.4 mg weekly | 14.9% | 2.4% | 68 | Adults with obesity or overweight, without diabetes |
| OASIS 4 | Wegovy pill 25 mg daily | 13.6% | 2.4% | 64 | Adults with obesity or overweight, without diabetes |
| STEP 2 | Semaglutide 2.4 mg weekly | 9.6% | 3.4% | 68 | Adults who were overweight or obese, plus type 2 diabetes |

What makes it stall, and what helps
- See where you are in the dose steps. Every trial listed above shows less weight loss at the lower doses
- Over the past month, count how many doses you missed or took late
- Keep a record of a few days of food and drinks. As portions shrink, liquid calories and grazing build up
- Include protein at every meal and keep up strength exercise, so most of the weight you lose is fat.
- Look at your sleep and stress, because both affect appetite.
- Ask your pharmacist whether any other medicine you take might cause weight gain.
- If your progress has stalled for months, ask your prescriber about switching medicines. Also ask about checking your thyroid or blood sugar.
