Okay, I see... I'm holding this thing upside down.
Was also reading kilograms as pounds... working roughly from the averages, looks like that 1700 calories a day figure you gave might be about right for the daily average intake for the month. I guess that does change things some--it's plausible for your metabolism to slow down enough to explain the numbers, for one thing. The 3500 calorie/pound of body weight lost thing is a little silly. But if we assumed it was true, that two kilograms you lost the last 30 days translates to 466 calories a day, roughly 2166 a day. That's a pretty plausible daily calorie burn.
I always find anything but rapid weight-loss pretty frustrating, myself. Get under the rate at which water normally fluctuates, and a lot of the time it really is hard to tell what's going on.
For the hundred days, you've lost 10 kg by the scale. If for the calendar year, you've lost 25 kg's it looks like things have accelerated? Even the last month, you've lost about 2 kilograms. That's only 24 kilograms a year. I wouldn't call this a stall so much as a dissatisfaction at the rate of loss.
Within low carb, you pretty much have two options (since you've already restricted calories). You could increase the ratio of fat to protein, make the diet more ketogenic. Or you could decrease the ratio--eat more protein, slightly less fat. I've used both--I used a high protein version of Atkins to lose weight, went higher fat for maintenance. For some reason, while high protein served me well while losing, once I'd lost the weight, I became prone to binging on "trouble" low carb foods like nuts, peanuts and cheese. Eating very high fat--around 85 percent--stopped the binging tendency.
