I'm seriously considering joining the next bootcamp. I need to lose about 10kg and also need to break my sugar addiction. I did a low carb diet many years ago and it worked brilliantly and I felt amazing after the first few days. However, at that time I wasn't doing any exercise. Now I train at least 6 times a week and I'm not sure how this will work with low carb.
I know I can fuel well before and after on protein and fat but what about during exercise? I usually use gels/energy bars/energy drink and I'm not sure what I could substitute that with. Anyone got any ideas? It's the only thing that's stopping me from going for it!
On the whole low carb makes you feel less hungry - once you get used to it. I know a lot of people who follow a Paleo diet refuel post workout with sweet potato / banana etc and that seems quite acceptable, but not needed before or during. Might be different if you're doing Ironman triathlons or something though.
Hmm well the Ironman is not til next year but we're talking regularly running for over 90mins/cycling over 2 hours. I just can't seem to find any info about whether that sort of exercise is possible without quick release carbs. If its not, then I guess there is no point doing low carb the rest of the time. But I really want to!
I think you might have to try and see how you get on. Runner's World had an article last month/recently about exactly this, the claim was that if your body hasn't adapted to be used to carbs then you don't need the carbs during your workout. So it suggested refuelling with starchy carbs after your workout but that you wouldn't need them before/during. It does say it's a controversial theory, though!
But if you try it and struggle, you might have to compromise to get your best performance - I would have thought that the post-exercise window when carbs just get burned up would be effective, so you might find it's possible to do both?
Like Lordemsworth I have read recently, not in runners world though, that more often now, endurance athletes eat a low carb diet and perform just fine. The key, though, is to eat low carb consistently, so that your body becomes used to it and 'fat adapted', which means it relies on fat for energy rather than carbs. That way, they never end up 'bonking' because to reach that point you would have to run out of body fat completely...pretty unlikely .
Oh, also, anecdotally, DH is a cycling fiend and we were on holiday recently in the French Alps, where the Tour de France usually does its mountain stage. DH's friend, who is quite fit, but doesn't really do much cycling, joined him for a ride one day. It was a gruelling three hours, almost 2.5 of which was climbing very big mountains . He managed it just fine.
I am really interested in nutrition/exercise and happened to get into a chat with this guy later and it turns out that since about 18 months ago he has been staunchly low carb. He had no idea of the stuff in my post above but definitely agreed that he didn't struggle at all energy wise. Very interesting stuff . I'd be fascinated to hear how you get on if you try it OP.
Capitola have a read of this article. Might help you. I really rate this guy's approach to exercise and diet, you can sign up for his regular articles if you are interested. He advocates clean eating (low carb) and 3-4 short training sessions per week comprising resistance training and high intensity intervals. It certainly looks like it works for him and his wife .
The best stuff on the whole issue of low carbs I have seen is a guy called paul jaminet on perfecthealthdiet.com. He explains that often low carb can work quite well for a while - even with exercise - but that in the longer term it can make people quite sick. Dry eyes, lack of mucus, gut issues.
I am convinced now that moderate carb (but no grains,gluten) makes more sense
Fwiw I try to eat 60-100g of carbs a day most days and I get on fine with grains, but avoid pasta, potatoes, pastry/white bread. I also exercise 5-6 days a week not for extended periods but high intensity (heavy weight training and HIIT sessions or kickboxing). Works fine for me.
