1. Protein Powder
Why It Helps
Protein powders, such as whey or plant-based options, support weight loss by promoting satiety, preserving muscle mass during calorie restriction, and boosting metabolism. They help regulate appetite by slowing digestion and supporting muscle growth, which burns more calories at rest.
