Many bars can support weight loss if they are high in protein and fibre while remaining low in added sugars. Look for options that keep you satiated between meals without exceeding your daily calorie target.
Protein bars focus on muscle repair with higher protein content, often lower in carbs. Energy bars prioritise carbohydrates for immediate fuel during endurance activities, with varying protein levels.
