” 1200 to 1400 “
Not saying your body type, weight, exercise, age, etc. isn’t appropriate for those few calories, but that isn’t much for sustaining most people. The “elderly”, and I use that term very loosely here, can make do on that, but anyone on those few calories must watch the ratios of nutrients in their diet. Anything under 1,000 is considered unhealthy and potentially dangerous.
Registered Dieticians working at assisted living or nursing facilities have a hard time keeping the proper balances for their residents due to the low calorie intake while still trying to ensure proper nutrition.
My internist has assured me those are appropriate caloric intake levels.
And my percentage nutritional targets are being met.
