Hi. The advice most of us would give for eating is to cut the carbs right down and have enough proteins and fats to keep you feeling full. There is a common tablet prescribed for T2 (Metformin) which helps a little but only a little. Diet is always the highest priority. If you are diagnosed with T2 be aware that metformin can cause bowel problems for a week or so so don't start it if prescribed until after your flight. Have a good trip.
