Hi, thank for using healthcare magic It can be difficult to lose weight. There are different weight loss diets that can be used and the response can vary from one person to the next. If you are sticking to the calorie and fat restriction of your low fat/low calorie diet and you are still having difficulty losing weight then you can consider low carbohydrate diet. It may work better for you. It is stated to work because the reduced use of carbohydrates lowers the insulin that is released. Insulin prevents the breakdown of fat , so lower insulin means greater fat breakdown. In addition there are weight loss medications that can be helpful. I hope this helps
