I found the link back, maybe you should read this:

I hear ya on the frustration. I was in a similar situation but got back to losing again just a day or two ago. But I was definitely stalled for a week or so, and I've been at keto for about a month, so also fairly new to the game (and this is my first go at it.) The only thing I can suggest since you're pretty well versed in the science is that you should track your measurements and not just your weight. We all know that weight can fluctuate with water retention or if you gain muscle while burning fat (a reasonable expectation if you're working out regularly) but measurements don't lie. Keep it up, and I hope you break through your plateau soon!

Hi
I understand your frustration, it has taken me 2 years to get into ketosis. I'm now in the groove after reading a book about low carbing for athletes. I realised that I wasnt eating enough fat and too many grams of protein. I've cut my carbs from 50g to 30g and reduced my proteins to 0.6g per lb of lean mass.... the rest of my cals are working out to about 120g of fat. I realy hadn't realised just what a change I had to make in my diet to get into ketosis. That happened about a week ago and I'v lost 6lb this week, having struggled with an upward trend this summer, even though I cycled across europe for 8 weeks.

Here are a few mor tips you may find helpful:

1) if you eat too much protein, your body will convert excess into sugar, and then that counteracts the ketosis metabolic reaction as by indirectly adding more sugar to your diet. Don't eat more than 1.5 grams protein per kg of lean body mass. That's all you need to survive.
2) drink several glasses of water per day. I'm on a lchf diet too and notice that I don't do well on days that I skip drinking water. Helps to flush out the crap.
3) take a multivitamin supplement like centrum, omega 3 fish oil and vitamin D, I do that so my body doesn't go into freak out mode thinking it's not getting nutrients
4) you mention that you got your calorie set point from a variety of calculators on the internet, but didn't clarify wether or not you used a calorie deficiency in your formula. For example, to lose about a pound per week, you need a calorie deficiency of approx 3500 calories per week. Calculate the number of cals you need to survive in a week, and then minus the 3500. That should be your calorie set point for the week.
5) don't base your macronutrient % without considering how many carbs and protein you should limit yourself to. First figure out your daily calorie target using the 3500 calorie deficiency as described in (4). Then set your limit to 30 carbs max per day. Figure out how many calories 30 carbs are (120 calories), and minus that from your daily calorie max. Then figure out how much calories in protein you should be eating (1.5 grams protein per kg lean body weight, and there are 4 calories per gram protein) and minus that from your daily calorie target. In the end, the remaining calories after minussing the carbs and protein allowance are the calories you should be consuming as fat. This is a more accurate way to calculate your macronutrient needs. The 10/20/70 % rule is a rough rule of thumb, only works for people within a certain height and weight category. If you are outside that window (like I am) it will throw off your numbers.

Sincerely hope this helps. Hang in there tiger.
