@Mike Bike & krouxsa - I am sensitive to milk, but have not had that much of a response from it. Sometimes you have to look past the obvious things, and silly as this may sound, it may even be the tea that lifts your blood sugar (if you are really hypoglaecemic). I only started drinking coffee when I started doing LCHF and was experimenting with bullet-proof coffee and at one stage found that I had inexplicable spikes in BG. Lo and behold, it turned out that I was sensitive to caffeine like that. On a slightly different note (but still on this topic), I pushed my carb consumption up a little over the last week to see what that would do to my BG readings. For the past 6 days I have been averaging about 150g of carbs per day. My waking BG for the last 3 days has been 6.3 - 6.5 and random tests during the day (I don't eat lunch) gave readings as high as 7.8. This morning I had my regular fatshake with no added carbs bar the 6g that comes with the PVM protein powder I use and that which is in the milk in the shake. My BG now is at 5.8. What I have learned from this is that (I am a Type II diabetic so keep that in mind): 1. There is definitely a cumulative effect to carb consumption for me - I don't "reset" overnight and high carbs consumed today will have an effect on my BG reading tomorrow. Exercise at night also did not do a "reset". 2. Since starting LCHF, my "tolerance" for carbs has lowered. I used to be able to get away with about 100g of carbs during the day without adverse BG levels, now I start seeing my BG going up well below 100g per day. 3. I have had slow and steady weight loss over the week prior, but as soon as I upped my carbs to about 100g/day my weight loss stopped and I have in fact added about 1kg back over the last 3 days. 4. Blood ketones are at 0.6 mmol, which is not bad, but I am not seeing any weight loss effect from that and I am guessing that the high carb = high BG is simply blocking any benefit that being in ketosis may have. I have tested with Ketostix throughout and have been reading +++ throughout, so my overall ketosis was not affected, which is interesting - I am guessing if I took even more carbs it would knock me well out of ketosis. I know that it will take me about 2 - 3 days to get my BG levels to the low 5's by simply restricting carbs again. I have trained throughout and have not felt any benefit in terms of energy or endurance over the last week, and over the last three days I had major energy dips in the afternoons, reminiscent of my high carb days. I am, therefore, resigned to the fact that for my own health and sanity I will have to remain low-carb.
