One Bite Me bar is a snack portion, so it does not replace a complete Shake Me meal like for like. The US bar provides 180 calories and 10 g protein, while a full shake serving provides 310 calories and 20 g protein with a different nutrient profile.
If you cannot have your planned shake meal, choose an appropriate regular meal and continue from there. Do not routinely swap lunch for a smaller snack just to use fewer calories. We can help you review a meal pattern that is easier to follow.
