Separate what you truly want from the blocks holding you back. Then act on what you truly want, asking God first for guidance.
If you really really want to lose weight forever, it takes consistent, positive eating and movement patterns. But more often than not, old habits cause you to ignore your goals and then you eat too much again. Go off your food plan. Sit all day, and forget moving.
Pay attention to that positive desire today, all day, and every day, all the time. Repeat it over and over again, silently to yourself, to others, write it down, tell it on the phone to a friend, mention it to everyone you meet. Say "I want to be the best I can be today. That's my goal. I want to really be good to myself."
Then absolutely, positively do NOT let yourself slip back to old patterns of self-destruction.
