View your daily calories as the amount of cash you have in your wallet; NOT an unlimited credit card!
Limit calorie spending to the amount of cash you PRE planned to spend. Eat filling foods that are low cost/cal. Don't waste calorie money on junk that leaves you w/ buyers' remorse & extra pounds.
And count EVERYTHING; it's easy to nickel & dime yourself out of your weight loss.
Bonus: intentional movement & exercise become money in the bank!
Live cheaply, spend wisely, be healthy.
