Plateaus are normal: as you lose weight your calorie needs fall and your reduced appetite catches up. Adding strength training, auditing protein, or a dose step-up usually breaks it.
Often, yes — studies show people regain much of the weight after stopping, because the underlying appetite biology returns. That's why a step-down to maintenance is preferred over stopping abruptly.
Around 15% of body weight with semaglutide and up to ~20% with tirzepatide in trials over roughly a year, when paired with lifestyle changes.
On average 10–12% with semaglutide and 14–16% with tirzepatide by six months, alongside diet and activity. Individual results vary widely.
Trial data suggest 5–7% of starting weight by 12 weeks. If you've lost under 3%, your doctor will reassess the dose or molecule.
Realistically 2–4 kg in the first month, much of it as appetite drops and water shifts. The early weeks are mostly about titrating up, so don't judge the medicine yet.
The abdomen, outer thigh and back of the upper arm are all fine, and absorption is similar enough not to worry. Just rotate sites and avoid scars or stretch marks.
No. Pens are designed to deliver an exact dose; splitting risks inaccurate dosing. If a dose feels too strong, the answer is to slow the titration, not split pens.
It doesn't matter — the weekly injection isn't tied to meals. Oral semaglutide (Rybelsus) is the exception and must be taken fasted with a little water.
These are treatments for a chronic condition, often taken for years. They don't stop working over time; stopping usually brings appetite — and often weight — back.
Once you've reached your goal and held it for several weeks, your doctor steps you down to a maintenance dose — usually one or two steps below your peak.
