Try to choose a lower sodium soup as well. If you do this consistently you will be more successful with your weight loss.
Take notes while dieting. From foods eaten to exercises performed, more and more research is showing that people who keep records of their weight loss journey are more successful and can even lose much more weight than those who do not. Writing everything down forces you to hold yourself accountable and take responsibility.
Even if you're in a fast-food restaurant, and are stuck with choices like greasy burgers, you can still take small steps to ensure you are taking in fewer calories. Order a large cheeseburger, take off the bun and cheese, and eat the patty. Dropping the cheese and bun will take a couple hundred calories off the 513-calorie total, and since the beef patty is all protein and fat (no carbs), you'll be no less full than if you had eaten the bun.
