Month 1 Semaglutide Results: Foundation Phase

The Science Behind These Numbers
These aren't marketing claims — they're based on the STEP 1 clinical trial, one of the largest weight loss medication studies ever conducted and published in the New England Journal of Medicine.
› 4 weeks: -2.3% body weight (-2.8 lbs) vs -0.5% placebo› 12 weeks: -7.4% body weight (-9.3 lbs) vs -1.7% placebo› 28 weeks: -12.4% body weight (-15.8 lbs) vs -2.4% placebo› 68 weeks: -14.9% body weight (-19.1 lbs) vs -2.4% placebo› 86.4% of patients achieved at least 5% weight loss› 69.1% of patients achieved at least 10% weight loss› 50.5% of patients achieved at least 15% weight loss› 32.0% of patients achieved at least 20% weight loss
Note: Real-world results typically show 10-20% lower weight loss than clinical trials due to stricter trial adherence, regular counseling, and motivated participant selection. Still — the results are substantial for most patients.

Frequently Asked Questions
How much weight can you lose in the first month on semaglutide?
In the first month on semaglutide, expect to lose 2-6 pounds as you start at low doses (0.25mg). Most weight loss begins in month 2-3 as doses increase to therapeutic levels.
How much weight can you lose on semaglutide in 3 months?
Most patients lose around 8-15 pounds by 3 months on semaglutide, depending on their starting weight, dose progression, and lifestyle changes. This is often the stage when appetite control becomes much more noticeable and before-and-after changes start to show clearly.
How much weight loss is typical after 6 months on semaglutide?
After 6 months, average semaglutide weight loss is 15-25 pounds (12-18% of starting weight), with many patients reaching their goal weight or plateau phase.
When do you see the best semaglutide results?
Best semaglutide results typically occur between months 4-8 when you reach maximum doses (1.7-2.4mg) and your body fully adapts to the medication's effects. The STEP 1 trial showed results still improving at 68 weeks.
Do semaglutide results last long-term?
Semaglutide results can last long-term with continued use. Most weight regain occurs if the medication is discontinued without lifestyle maintenance strategies. Patients who gradually taper and maintain healthy habits keep off 30-50% of their weight loss.
What factors affect semaglutide before and after results?
Results vary based on starting weight, diet adherence, exercise habits, genetics, medical conditions (PCOS, hypothyroidism), medication compliance, sleep quality, and lifestyle factors. Diet quality alone can affect results by 20-30%.
