I was really going for the 30 days, which I alone could do, despite being hard, shopping and cooking 'normal' meals for my family.
Tbh my wife stepped in because she saw me struggling mentally. She made a big batch of pulled pork for us all to eat together, and requested the fresh bread to go with it. Then she asked me to join the family and to give the carnivore thing a rest for now.
It's been great to have a food reset though. Cutting sugar is always good at least, as it's interesting to note how it creeps in to our diets.
I actually had zero tolerance to sugar, dairy and most food additives when I was a young child, and had a very restrictive diet, missing out on many sweets, treats and Birthday cakes. I seemed to build tolerance over the years. But I still notice signals if eat too much sugar in s short space of time.
