I've found the carnivore diet to my liking. I lost 7 kgs in two months with no exercise and one of those months was Dec and let's face it, I went off diet plenty for Christmas parties. Hubby lost 5 kgs in 2 weeks doing it properly. If you can water fast for that long, you can definitely survive the discomfort of carnivore and the sometimes getting bored of eating the same foods.
