There’s no set timeframe for losing one inch off your waist and it’s impossible to predict where your body will lose fat first or last. The rate at which you lose inches off your waist is also dependent on factors such as genetics, age, and overall body composition.
However, a healthy and sustainable approach to weight loss typically results in a slow and steady reduction of body fat over time. This means that losing one inch off your waist may take anything from two to four weeks or more depending on your starting point and your consistency with diet and exercise (6).
