Dietitian's Tips for Consuming Whey

  • Metabolic Effect: Whey supports muscle repair and provides energy due to its rapidly absorbed protein content. It may cause digestive problems in some people due to its lactose content.
  • Consumption Recommendation: It can be consumed after exercise or to meet protein needs. Those with lactose intolerance should prefer lactose-free alternatives.
  • Things to Consider: Those with high blood pressure should consume it carefully due to its high sodium content. A glass of whey contains approximately the same carbohydrates as half a serving of fruit.
  • Exercise Equivalent: To burn the calories from a glass of whey, you need to walk at a light pace for about 11 minutes. You can plan this walk in addition to your daily activities.
