I'm am no expert...by any means. But that seems reeeeeally low to me. Are you lacking energy at all?

Maybe you're pregnant.

I stay under 10grams per day and it hasn't affected my cycle or my energy. In fact my energy levels have been higher than I can remember and have not needed carbs to give me energy to do my high intensity workouts. I also had non-existent cycles, often needing to take Provera in order to bring a cycle on after months of nothing. I have been doing low carb now for nearly a year and it has also not affected my kidneys, I've had blood work done often since I started eating this way and all of my results have come back good. I used to shoot between 20-30 grams per day and I stopped losing.

By looking at your food diary, I'd say you're not eating enough. I think anything under 1200 calories is too low. I'd almost wonder if that had anything to do with af being mia. Did your doctor tell you how many calories to aim for? And how are you feeling? Metformin can be dangerous if it makes your blood glucose levels too low.

Wow that is really low. From my understanding, I thought low carbers weren't supposed to go under 20g/day for an extended period of time. I don't see a lot of veggies in your diary which would concern me personally and I think low carbers favor berries, so I'd also look into that.

I am no expert though as I'm in the 200 carb/day range.

My endocrynologist and nutritionist recommended at least 120g a day so I would say you are eating low. Atkins and South beach will take you lower than that but the question would be how sustainable is extreme low carbing? Do you intend to eat that low for the rest of your life when you are at goal and trying to maintain?

Do you want to be down that low? I always thought you had to be but imo i dont think it is necessary. When i did that low of carb i wasnt eating too well, i ate alot of meat, higher fat because it had no carbs and didnt eat too many veggies because they would put me over. I currently do lower carb, but i dont actually count, i just stay away from breads, pasta, grains and fruit - except apples and the occasional banana, and i have been having good success with it. I went alittle carb heavy last week to see if it would make a difference and it definitely did, i didnt lose. This week i cut those things out and im down on the scale.

I know for myself eating that low carb brought me to eat way high on the fat scale and it wasnt good fats most of the time because it came from meat. My body worked better with higher carbs from veggies and such and lean proteins. Not exactly sure how you eat but just trying to give you some options. I felt very deprived being the low carb and now i dont and im losing better then i did when i went super low. Just something to think about

Why are you eating so low on carbs? Is there a specific plan you are following?

Did your doctor say how many carbs? Because it was my understanding that a normal low carb diet is 100g carbs/day or less, sometimes 50g carbs/day is used as well. I've only heard the 20g carb/day as a suggestion for a very short period of time.

You don't need to eat potatoes but including more veggies and some low sugar fruits may be a good idea.
