Are protein bars a good choice?
Protein bars can be useful, especially for travel, work, and emergency meals. They are not automatically better than regular food. Some are basically candy bars with more protein; others are genuinely helpful because they provide a portable protein serving with reasonable calories.
Check calories, protein, fat, fiber, and sugar alcohols. If a bar keeps you consistent and digests well, it can fit. If it triggers cravings, bloating, or turns into an extra snack on top of normal meals, use it less often.
