I used to be an eat when and what you like person but May's type II diabetes diagnosis (possibly resolved now) introduced me to a totally new concept (for me), moderation! OK, I had fairly major other health issues in the interim but as a result of the new lifestyle, I've dropped from rather too close to 21 stone to a touch under 17 and as a result of the diet change and my new fitness (comparitive) and exercise, my blood sugar levels are those of a "normal" person, although I'm still on one 500mg Metformin tablet per day tohelp, to be reviewed in Feb.
Mealtimes are very variable - during the week, Friday is the only day when a normal timetable exists. On Mondays, my wife has a relatively late start to her day, leaving for work at about 08:15 or so but not getting home until 20:45 or thereabouts. Tuesdays and Wednesdays are both early starts with her being out of the door at 06:30ish but home at 17:45. On Thursday, she's out early and late back.
As a result of my surgery and probably other factors, I'm waking up at about 04:00 most mornings and having my brekkie at 06:00, possibly with a coffee a bit earlier. Lunch (when I remember it!) is usually as close to half way between breakfast and the evening meal as I can remember to eat it with the evening meal being at 19:00 or 21:00 depending on HER return time.
On holiday, we tend to rise a bit later (or have in the past) so breakfast tends to be 09:00, lunch at 13:00 and dinner at 22:00. Maybe a few nuts or Ouzo snacks (the Greeks almost always have a little something with spirits) in between but rarely a real snack. Again in the past, we've tended to have a mini Mars bar (or Lidl equivalent) at bedtime but that's a thing of the past now.
