Hi All, It is well known that the recommended kilocalories per person, per day, for an adult not doing physical labour is 2100 kcal. But is there an 'emergency threshold' for this same metric? I.e., if I am only consuming 1700 kcal per day, have I crossed an emergency threshold, and if so, where is the source that establishes this as an emergency threshold? Thanks for any help - we are looking for a precise threshold, with a specific source.
