You can do caloric deficit diet. Surely you will lose weight.
Go first from three meals a day to two. Learn to like being hungry, since every hour of it is bunches of calories burned.
Then go from two meals a day to two. Very shortly you wil lose quite a bit of weight.
Always enjoy the hunger.
It's really that simple.
I was following you here until you suggested going from
2 meals a day to two?If you made an error and were simply implying to eat once a day, I would not recommend that.
