SNAP! - Apart from the children - I only have 2.
I'm glad it helped. I started on a strict calorie controlled diet initially (at about 1500 calories a day - but this is probably too low) until I lost the first 10Kg or so (that took about a year of diet alone) and then realised that I was going to have to start gym work to lose any more as I plateaued for the best part of a year. When I started the gym work I stopped the strict calorie controlled diet and coming from such a low calorie diet made it easier to just "be careful" with both calories and carbs. So I don't count them now as such but if I had to estimate, I would say I have around 1800 calories/day (although this is bit of a guess and could be several hundred calories out - in either direction!) and my pump tells me my average daily carbs for the last 30 days are 128g - but this does include Xmas! I guess I would have around 100-110g CHO usually.
Your diet and exercise plan sound absolutely fine to me. I go to the gym about 3 times/week on average and probably eat more carbs than you do. My HbA1c is around 45-50 (6.2-6.7 on the old scale) but my basal changes regularly that makes ideal control a bit more difficult.
I think the main thing is to not give up, think of it as more of a routine/permanent lifestyle change if possible. The other reason I started gym work, aside from the weight loss, was to improve my general level of fitness as I am retired and generally pretty inactive and I think it has certainly done this. If/when I start slacking on the gym, I can use this as motivation to return (I used to get out of breath walking up a slope or stairs - not now).
I don't know if I'm teaching my mother to suck eggs here as I don't know how long you've been going to the gym for and I apologise if you already know all this but I would suggest not going mad at the gym, at least until you have been doing it for a while - if you find it really hard it will be more of a chore to keep going. I calculated my HR zones and during cardio work, stick mainly to zone 3 with the occasional brief incursion into zone 4 or even 5 if I feel good (I eventually started to get endorphin highs which were pleasant enough to get me through a few minutes of zone 4/5). I do fairly tough weight machines as wel but only hard enough so that I can do 2 x15 reps.
I go through phases where I slack off on the diet or gym work if I don't feel up to it but always restart - I think the longest I've gone is about a month, so take a break if you need to but always try and return. I hope these tips help but I'm sure you'll adapt them to suit your requirements - we're all individual!
WOW - well done on the children by the way
Incidentally, your GP should be able to give you exercise on prescription (I think that's still going - although I've been retired for 7 years now) that will not only give you about 3 months free gym access (limited hours though) but also a fitness advisor that will work out an exercise program for you.
