@Mike_M_Klotz@BarelyStreetabl No way.
If truly 500 calories below maintenance you’ll feel hungry in the evenings.
If you don’t truly feel hungry ( and not give in) then you’re not eating under maintenance.
@Ajarncom My parents do since they retired. Dad has sleep apnea and uses a CPAP machine. Mom gets acid reflux so her bed is tilted up. They both wake up in the middle of the night at different times. Separate rooms just works better. Married 52 years already.
