Other than carrying gear to/from the boat, it's not terribly taxing since where I dive there aren't strong currents and I'm not usually doing any heavy duty swimming. That said, even without any major exertion, my metabolism usually kicks up into high gear just keeping my body temp up (a typical dive can be an hour long in 78 degree water; given a 'normal' body temp of 98.6 and the greater density of water helping to more quickly take heat away from the body - even with a wetsuit - it can be a challenge keeping my core temperature up). Typically, I'll do two of these dives between breakfast and lunch.
I'm figuring at this point that I should probably add a protein bar in between the two dives. Any thoughts? I won't be back in the water until later this month so by that time I should be pretty well acclimated to the diet.
Your question got me curious on scuba diving calories burned so I looked them up. I'm assuming you'll be down to 148 on your dives; the sparkspeople site says you would burn 473 calories for a hour of scuba diving.
Since you are used to the medium intensity rides, I would start those back up at a lowered intensity once you feel you are in ketosis. That should give you both an idea of how you will feel and help your body start to learn the new fuel source for exercise before your dives.
Not sure how much you would typically eat before your dives.
Let's say a shake AND 2 whole eggs for breakfast (gives about 260 calories) then your bar between dives is another 160. After the second dive, assuming you still feel like you can handle it, I would have something like the mango ready to drink at 200 calories. Then have lunch (maybe flip dinner & lunch) with 8 oz of protein & veggies within an hour of the second dive. Still have a snack and have dinner as an IP and veggies. Be sure to bring salt in case the first dive is intense enough that electrolytes are impacted.
Even a Zumba class that I did at an extremely low intensity after 1 month on IP really wiped me out, but, sadly, I had not worked out for maybe 3 years prior to that. Once I got back into the swing of things after 6 months on IP, I really needed the extra calories & nutrients from eggs and extra IP around workouts. I played around with it on a daily basis, thinking that I really shouldn't need the extra packets, etc. But I was wrong! I could get by with not needing an egg/eggs after a while, but the packet before and packet after followed by a meal is something I still do in maintenance. (5x per week, about 60 min weightlifting and core work).
My weight loss became more consistent week to week after exercise, but by then I was close enough to goal to be losing in the 1.2 to 1.8 lb/wk range anyway, both in the month before I started working out and the month & a half to hit goal after.
Your results will vary, of course.
