The bulk of research suggests that the ketogenic diet is more effective than conventional diets in helping you lose weight and shed body fat. One of the reasons why the ketogenic diet provides such reliable weight loss results is because it consists primarily of highly-satiating whole foods like meat, high-fat dairy, and low-carb vegetables while removing all carb-rich, sugar-laden processed foods from the diet. By eating in this way, you will feel full while eating fewer calories and losing weight.
Finally, if you want to speed things up a bit I can highly recommend switching to intermittent fasting for your meal frequency which is not eating for most of the day then eating in just a short window of a few hours, can be whenever is most convenient for you but I find afternoon/evening window works best, the shorter the window the better, this can be quite hard for a lot of people to begin with as your brain is trained to expect food at certain time of the day but it doesn’t really need it, and after a few days of doing it you won’t get hungry anymore at those times as your body will be quite happily burning your stored body fat for fuel 🙂
