Dietitian's Tips for Consuming Whey (Powder)

  • Metabolic Effect: Due to its high protein content, whey powder accelerates muscle development and repair. Thanks to its rapid absorption, it is suitable for post-workout use. High lactose content can cause digestive problems in sensitive individuals.
  • Consumption Recommendation: It can be used as a protein supplement after exercise or between meals. It is recommended to consume it by mixing with liquid. Those with lactose intolerance should be careful.
  • Things to Consider: Portion control should be observed, excessive consumption can lead to weight gain. A serving of whey powder has approximately the carbohydrate value of a small banana.
  • Exercise Equivalent: To burn the calories from a serving of whey powder, a brisk walk of about 7 minutes is sufficient. You can plan this short walk in addition to your daily activities.
