Thats some weight loss diet and have often wondered about the Mountain house meals, mainly to stories of the high sodium content. Its good to hear your energy boost during the experiment.
I bet it also saved on water used for washing up and thats good right lol.
This kind of experiment is a good exercise in order to establish a base-line of what you can and cannot do or cope with.
No doubt it has given you great confidence in your resources and food intake measures. YOU now know what you have to do or eat for sustainment, others may still be questioning THEIR requirements (especially when there are numerous family members) = They'll have to 'brass it out'!
Thanks for the mention/shout out - You endured so we could learn.
