Hi and welcome. As others have said keep the carbs down; no need to stop completely but have low-GI ones when you can. Don't interpret the HF bit of LCHF as a need to stuff yourself with fat; just have enough to keep yourself feeling full and satisfied. Protein is fine and so is non-root veg and some fruit (not exotic due to high sugar). A blood sugar of 27 is not good and will be starting to do harm and may make you feel tired and irritable; into the 30s and you can be in trouble. With a low-carb diet the BS should come down fast. As others have said, I would avoid any of the slimming clubs. First they or their products cost money and most still live in the old world of calorie-counting. Diabetics need to think carbs and so, in fact, does everyone but you can't change the world overnight
