Hi ma5on,
One mistake sometimes made is that people reducing their carb intake still rely on a carb./insulin ratio to calculate their doses. On a diet low in carbs but higher in protein, a greater proportion of that protein will be metabolised into glucose. A zero carb breakfast, bacon and eggs for example,will still need insulin to cover it.
I noticed your lunchtime dose was very low - 1 unit - for chicken, salad and coleslaw. A bit too low a dose for me, and for you too it seems. Lunch for me today is chicken breast, mayonaise, pesto sauce, 2 celery sticks, 1 slice low carb bread with butter & cheese, coffee with cream. 2.5 units insulin.
Try increasing your doses a lttle. The ketones also are likely a symptom of insufficient insulin and will subside as you adjust your doses to suit your new diet.
All the best,
fergus
