It is not appropriate to give a fixed “kilos per week” number for vinegar water. Weight change depends on calorie deficit, water balance, sleep, stress, activity level, and starting body weight. Vinegar may offer a small, indirect support for appetite or meal control in some people, but it is not a primary weight-loss tool. High doses can cause irritation and reduce consistency. The realistic goal is not a one-week miracle but a sustainable plan executed over weeks and months.
