Get yourself over to reddit.com/r/keto. I’ve been on Keto which is a fancy way of saying fat adapted since October. I’ve lost about 17kg, 107kg down to around 90 but my scales ran out of battery two weeks ago so can’t give an up to date account.
I started the diet to lose weight after finishing my first and very painful half iron man at 107kg and deciding that enough was enough. Losing the weight has been great but the biggest advantage has been not needing to eat during extended exercise. I can now get back from a cycle in the morning with no more than some eggs for breakfast and forget to eat lunch, where before if I didn’t eat every hour on a ride I would feel awful.
YMMV and IAMNAD etc etc but it worked for me!
