Um, you mentioned you're currently eating around 40 carb grams a day. Why don't you go back to Induction level of 20 total carbs a day (don't subtract fiber grams)?? And are you eating enough fat and calories? You should be consuming 10 to 12 calories per lb. of CURRENT body weight, and ideal fat intake around 60%, higher is fine.
I was stalled out for months, and by upping my calories from 1200 to 1700 per day, in the form of more fat (olive oil, mayo, flax seeds) I finally got things moving again ... plus exercise, but I had been doing that anyway.
Too few calories (minimum 1200 per day) will slow your metabolism to a crawl ... because the body is VERRRRY adaptive .. less fuel coming in, it turns the "thermostat" down to conserve.
Of course, you may try the fat fast or Stillman for a few days (I tried Stillman last fall ... very difficult, and not very palatable ..
) but it would be worth revisiting Induction for a few weeks.
Just reading what you eat ... I can't imagine where you're getting the 40 carbs from. I use fitday as well, and found I had to "customize" some of their figures, because the food I was eating was way different than what they listed (eg, they have smoked turkey sausage at 8 gm carb for 3 oz .... the brand I buy is 0.3 gm for 100 gm serving, which is a bit more than 3 oz)
Hope this helps, and keep us posted ..
