Correlation / Causation? Over what period was the weight loss / improvement?
Yeah well exactly. A lot of confounding factors.
Went something like this:
April 2015 - Font trip on minimal to no climbing let alone anything resembling training whilst working hugely unenjoyable job in A&E. Two 6Cs one in two sessions.
Big hiatus after this. No diet moderation.
November 2015 - just about managed to climb Devonshire Cream 7a at Ansteys, only sport route of the year. New job for a few months, happier, new found motivation. Started regular indoor bouldering again. Very undertrained, some sessions resulting in DOMS lasting until next session. Stayed consistent though.
Jan 2016 - started new diet, minimal to no alcohol, no shit, lots of vegetbles, sweet potato, lean meat etc. Weight post Christmas binge about 82kg. Dropped several kg quite quickly, first week even, probably water weight. Felt far far better without the booze though, trained more, less excuses.
Around 20th Feb 2016 - Font trip, did first 7A. 8 7A total that trip. Probably weighed ball park 73-74kg
March 2016 - French 7c in a session. Still my maximum grade though, partly though lack of trying due to more focusing on bouldering, of which max grade is just 7B at a push and not many of those.
April 2016 - 72.8kg. Minimum weight, have more muscle since then and a bit chubs right now for sure.
