Been ketogenic for 8 months now
No bread, pasta, rice, spuds, sugar, and very little fruit other than a few berries. Dropped from 87 kg to 75kg and feel great. General mood is much better too. No carbs other than low levels in veg and lots of lard / olive oil / omega 3 oils. Meat / fish, lots of veggies and eggs are where it is at folks.
The count calories . 'eat a balanced diet; thing sounds like good sense. Everybody down the pub will nod and agree. Except it is wrong. Simply wrong. Half the modern diet is some sort of cheap corn / potato/ rice based unhealthy junk. We are not evolved to eat the stuff. Fatness, t2 diabetes, leptin resistance, inflammation are the result.
