Nutrition deficiency? Watch
If I was on a diet, and say I don't eat enough so I get nutrient deficient. How quickly does it take/how quickly would you notice yourself become nutrient deficient? How quickly would it take to replenish these nutrient deficiencies?
It takes quite a long time for you to actually become properly deficient in anything and the less time it's been the quicker it will be to replenish things. Short term (like a couple of weeks or something) it's probably more of a shock to your system kind thing than actual deficiency and just starting to get some more stuff in you should improve things and help prevent that proper long term type of issue.
If I tried to increase nutrient levels today, and for the next week per se, when would I feel better. Would it be more instant/short term like a day?
I have a feeling I've replied to another one of your posts where you're saying you're having an odd feeling in your throat and feeling generally ill. In your case I expect that you're probably a little bit ill with something (potentially partially down to you being a bit weakened with less nutrients). So you'll probably have to wait for that illness to pass before you'd actually feel any better with changing your diet. It would still absolutely be a good thing to improve your diet whenever you can though.
It's all quite hard to actually predict cos it depends on multiple factors and will be a bit different for everybody.
