Are you eating lots of protein?
When I eat a lot of protein I find that it feels me up for longer periods.
I do get days when I can eat more than others, and I know that I have to watch myself as like you, I have a fear of regaining.
Some days I fall into bad habits of overeating due to feeling emotional. If you feel hungry then try and eat the good foods rather than the naughty ones
I found this info to be very helpful:
HEAD HUNGER VS PHYSICAL HUNGER;
HEAD HUNGER:
Comes on quickly, suddenly; you realize how much you want to eat
No physical signs (though we desperately search for them --
was that a stomach growl or just gas?)
Strong, intense urge
Often paired with strong emotions, places, situations or activities
Often involves desire or craving for a specific food
Unable to recognize fullness easily
PHYSICAL HUNGER:
Comes on gradually, intensifies as caloric tank gets depleted
Physical signs include stomach growling, gnawing, empty feeling that may escalate to light-headedness
and lack of energy
Would like to eat
but not desperate
Not linked to emotions,
places, situations or activities
Desire for food is not necessarily for one specific kind
Stop when physically full
I hope that this helps you
