The good news is that you can still enjoy your favorite In-N-Out meal without feeling guilty about the calories. For starters, you can opt for a protein-style burger that replaces the bun with lettuce leaves. This will save you an extra 150 calories while still giving you all the juicy burger goodness. Additionally, ordering a single patty instead of a double or triple will also cut down on calories without compromising on taste. Another way to manage your calorie intake at In-N-Out is by choosing your sides wisely.
