I'd also consider raising your carbs a little to see if that helps if the sodium doesn't -- even if you doubled your carb allowance to 40g that's still very low but allows for a lot more fruit and vegetable variety.

Energy come from 2 sources, the first and easiest is carbs, the second and harder is fat. You have reduced carbs, you must increase fat... No carbs and no fat equals no energy.

Can't see your food diary, but more fat than you think is "good fat" eg butter, cream, the fat on meat... all those things we were told were bad for us are actually good for us on this WOE when you restrict carbs. Don't only eat those good fats like salmon and other oily fish - they are lovely too but less filling. During your first week or two of adapting to low carb, don't worry about calories, just make sure you are eating enough to feel full. Trying to restrict calories too much during adaptation will definitely make you feel bad.

Good luck.

I use butter and hwc in my eggs. I cook with butter instead of nonstick sprays and put the hwc in the eggs before I scramble them or make an omelette.

Oh yes @Kitnthecat, I put some more butter on top, when cooked and is sooooo good! Okay, time to cook some eggs! Lol!
