Any tips on how to keep things moving. I think the lack of carbs leads to lower water retention which is responsible for the quick weight loss but I get constipated. Is it just me?

Hi Sugaraddict
Have a look at these posts for lots of ideas https://thebloodsugardiet.com/forums/topic/constipation-how-to-increase-fibre/
or just search constipation in the search box at the top of this page.
Further to what I wrote in those posts, I find that flax seed and chia seeds help me get moving. Sprinkle some of each (a couple of teaspoons) on some greek full fat yogurt and stir in. Leave for 15 mins or so for the chia seeds to soften a little. You can buy ground flax seeds (also called linseed) – or you can but flax unground. You can sprinkle on some cinnamon and some vanilla essence if you want to add some more flavour.
Merry
