Oh. This thing just made me desire to lose bodyfat more (well, I surely have way more you do, it makes some difference indeed)… As a smaller body needs less energy, it’s not that wasteful. I don’t worry about lack of energy, you see. It’s super easy to stock up enough calories to last a year or two… We surely have enough for quite a few months any time and several months if we use it sparingly and lose fat in the process (maybe muscles too but we have not very much to lose and we actually want more… but survival is more important).
Protein and the other various essential nutrients are another matter but it’s still not very difficult to get most of our needs from a good food supply we can get now for a very, very long time.
I probably could fast easier than the average person but I still prefer eating and as getting nutritious food with a big shelf-life is very easy (not necessarily my normal staple food but still, nutrients will be there and I won’t actually suffer eating them), I don’t see the need for long fasts at this point. At least for people like me who have big enough space to store food (and no one will eat up my precious supplies needlessly).
I will look up our supplies, I am curious a bit. I only know we have 20lbs of millet, 14lbs of xylitol (and 2 lbs of erythritol), the virus has nothing to do with that, it just happened but it’s not the normal amount in this household, there was a mistake and circumstances… Whatever, they will get eaten for sure before they spoil. The other things are not much, just the usual amount but together it must be enough for half a year if we lose our very unnecessary bodyfat in the process.
We definitely have some staples we only store enough for a few weeks. Probably because we use a big amount of them and we only use the cupboards to store all our food. Except the millet and the sugar alcohols (about 14lbs of xylitol), they are in a cardboard box, we have too much food to store properly right now. But we could store much more in boxes or just on top of each other.
I will write a list and stock up in the next month, I think (just a little more, I don’t want my living room to become a storage room). And then we don’t need to buy much carbs for months… 
But eggs and vegetables, if we can’t buy them for more than 4 weeks, that would be hard. I can be creative if it’s about my food, really but certain things are practically irreplaceable.
My SO has way more staples. Give me eggs and meat and I can be fine for long in necessity, I am sure of it. My SO would get totally miserable without huge amounts of chocolate, raisins, rice or millet (preferably both), rice flour, various fresh fruits, even bread (he lived without it for some years but that was before Marmite) and at least a little cheese, all must be present every week. He probably would miss eggs when I decided all the eggs are mine… That would be an interesting experiment, though. My empathy vs my selfish greediness! No, I can imagine the result. I probably would feed him eggs as I am that nice, 1 for him (or even an extra white or two), 10 for me. Or 20, it depends how well he handles that… I eat most of our eggs normally too, I love and need them way, way more. His plants are probably pretty nutritious to begin with but he can have as much meat as he wants (it never was much anyway). Just not too many eggs if we have a little supply.
Of course, he eats whatever he wants and able to. He just always let me control the distribution of the not carby part of our food just like he controls the carby parts even when I cook with them. Not completely but pretty much. And I know more about nutrition and make sure we eat well enough, I am the main cook.
Oh. It never crossed my mind before. It’s not only we in this forum probably eat way better than the average person and our body can handle problems better due to less burden… We know more about nutrition, even me who never watch videos, just read some articles with my around zero Chemistry knowledge. Just in average, to some extent, I don’t imagine keto is instant goodness, it doesn’t work like that. And it surely helps when people stock up and don’t go out and eat whatever they have. Even if it’s not very long term, our body works way better if we eat right. And we feel differently mentally, emotionally too.
And I’ve write about it before in some topic (I don’t always even notice which coronavirus topic I am in), if someone is willing to do keto, especially for health reasons, that person surely focus on their health anyway and willing to do more steps, even if they aren’t super comfortable and usual.
