samuri, that’s why a cyclical keto diet is great. <20g carbs per day in the week then you can pretty much eat what you like (sensibly, obviously) at the weekend. To me this seems very sustainable, it just takes a bit extra planning/prep to make salads or bake low carb almond/flax bread for lunches at work. Also, based on my friends experience, the weight doesn’t go back on when you hit your target weight and go back to eating carbs again, so long as you don’t go back to pigging out every day..
The only thing I’m missing is the convenience of being able to just grab a sandwich or something from the shops if I’m in a rush. Besides, what’s not to love about cooking up a big steak or some bacon and eggs loaded with cheese and still be burning excess fat?!
I don’t think cutting out carbs this severely is entirely necessary (I lost about 11 stone without cutting carbs) but it can help shift stubborn fat or overcome a plateau I reckon.
