I've been eating a carnivore diet for about 6 weeks. The weight does drop quite quickly. Introduce some carbohydrates though and the weight gain is staggering! I’m led to believe that eating carbohydrates, does introduce more water molecules or you retain more water, not really sure the full facts on this, but I will look it up.
We had a few treat days over one weekend, which included bread, chocolate and wine. That culminated in a 7 lbs weight gain.
I now know to be a bit more conservative regarding treat days. I did managed to do a 3 day fast last weekend (72 hours) just drinking black coffee.
I’m back to 197.6 lbs, so I’m almost back to 195.7 lbs, 9 days to get here.
