Unfortunately, how long it takes to lose weight (and fat) varies from person to person. I recommend having realistic expectations, because the weight you gained over the past few years or decades might not come off within a few weeks; it might take months or even years to reach your desired weight. However, the better your metabolic health is, the easier it will be to lose and maintain a healthy weight. For example, I recently dropped from 10.8% to 8.8% body fat in just a few weeks by reducing my carbohydrate intake from 120 to 75 grams daily. Coincidentally, I worked out much less than usual during that time period. I attribute that rapid decrease in body fat to my excellent metabolic health and my body’s ability to efficiently use all fuel sources (from body fat or food).
