Apple cider vinegar is not a primary weight-loss driver. At best, it may provide a small support for appetite or meal control. Increasing the dose to “lose weight faster” is not realistic and raises side-effect risk. The main levers remain calorie balance, protein and fiber structure, regular movement, and good sleep. If you use vinegar, dilute it, start low, and monitor stomach, throat, and dental tolerance. Claims like “how many kilos in one week” are not scientific targets. Build a sustainable system instead.
