Creatine vs. Whey Protein: Which Substrate for Fat Loss?
Auditing the two most researched supplements for body composition.
When optimizing for fat loss, the goal is to maximize the thermic effect of food and preserve skeletal muscle. Both Creatine and Whey Protein are essential, but they serve different roles in your Weight Loss Framework.
The Comparison Audit
Whey Protein: The Satiety King
Whey protein has a high thermic effect (TEF) and stimulates Muscle Protein Synthesis (MPS). It is the primary tool for meeting your 1.6g/kg protein threshold.
Creatine: The Energy Buffer
Creatine doesn’t burn fat directly, but it allows for higher intensity during Performance Peak sessions, leading to greater metabolic demand. Read the full Creatine Clinical Audit.
⚖️ The Verdict
For fat loss, Whey Protein is the priority for satiety and muscle preservation. Creatine is the essential secondary substrate for maintaining strength during a caloric deficit.
