Nothing like trainng for the job,
@Mel dCP !
From my personal experience and reading and dicussion with doctors and other TIDs over the years, not as HCP advice or opinion:
As i have said on other posts the pattern iof BSL response to exercise vaies from one individual, say me, who spikes within 1 hour of starting vigorous exercise and plummets 5 to 6 hours later, to those who say they plummet within 2 hours and maybe 3 to 5 hours later if they have not rebounded too much from the first instance. Others seem to stay oretty steady throughout the exercise and drop mildly later.
On keto diet and moderate exercise such as a 5 km walk carrying maybe 15 kg i get no spike and only mild lowering of bsl at the 5 to 6 hour mark. Also perhaps not surprisingly a hunger for extra protein around the 5 to 6 hour mark.
Pump settings: up basal by 20% ( = 120% on the Tandem pump) for 2 hours before the walk described above, and avoid any bolus with 1 hour of commencement ( as this has caused bsl dips during the exercise itself)..
On return, programm in 90% basal for 2 hours just in case bsl drops and add extra protein and associated 50% og protein grams of carbs in that calculation. I know you may not need to with some proteins.
Like i did in the days before bsl monitoring the insulin adjustments would vary according to weather ( more down adjustment in hot weather), and distance ( a likely portage of canoes on a canoe trip meant more chance of a hypo that afternoon or evening, EXCEPT now on keto the fluctuations are much less.
I also take more salt in after exercise these days and try to watch my hydration level like a hawk ( or these days like a daffy sparrow ( no offence to sparrows intended).
Finally i need to check my feet carefully to prevent or intervene early if blisters or bruising of toes should start to appear.
I wear well worn in boots and two pairs of good but relatively fine socks with the theory that the socks taking up the bulk of the friction is better than my skin doing so.
I wear wrist and ankle weights during the exercise in order to obtain some strength building and try to avoid waliking on concrete and other surfaces as much as possible.
Somehow though when i used to doing canoeing for exercise, the arm and leg weights did not seem like a good idea Glug, glug, glug..LOL
Best Wishes, maybe carry spare pump gear and hypo gear in case you run into trouble and whether you believe in divine providence or not, walking during a thunderstorm is not worth the potential 'power gain'!!
