My triglycerides were high when I went low carb. Even with the addition of a little more fat into my diet they dropped. My total and HDL went up a little but not enough to cause me any concerns.
I am not Keto, I bought a meter and by testing before and two hours after meals found my blood glucose dropped into the normal range on 85g of carbs a day and no more than 30g in a single meal.
There is no way to know unless you test - I had to fund my own meter but it's worth asking you GP.
Since getting into remission I aim for 120-130g a day.
