Fantastic!! Thank you for sharing this, @Figz
I’ve currently bee fasting evening meal to evening meal. Just having a couple of coffee’s in the day and then 4- 5 litres of water each day. I don’t find I get really hungry until around 4-5pm before I leave work. I can then get home and still go out for a 1-2hr run before having dinner. At the weekend I’m able to go for a 50-60 mile endurance ride without eating having just had a coffee before going and about 1.5 litres of water while out.
I think a lot depends how used to burning carbs your body is as opposed to fat. I try to keep my food macros balanced and not to over consume carbs or processed foods. I am however not currently doing any higher intensity training above Z3.
