Why both might fail you (and what to do instead)
Both can fail when the underlying drivers (sleep, stress, ultra-processed-food saturation, metabolic adaptation in repeat dieters) aren't addressed. If you've already tried both or one and bounced, the issue isn't macros — it's protocol fit. The Metabolic Damage Assessment maps your profile to a starter protocol that addresses the actual gap.
