Reversing Heart Plaque, Peptide Protocols & Biohacking Wins with Ben Greenfield | Ep #332

About this video

Ben Greenfield joins Niddam to discuss the updated edition of Boundless, his shift away from strict long-term keto toward a more Mediterranean and cyclic carbohydrate approach, and lessons from his own thyroid and hormone changes he attributes in part to chronic endurance training and strict ketosis. The headline segment covers how Greenfield says he addressed a concerning heart plaque scan through lifestyle changes combined with prescription lipid-lowering approaches and a supplement stack, under medical care. He also describes peptide blends he personally uses, presented as his own protocol rather than general advice. The conversation closes with work boundaries, family scheduling, afternoon rest and prayer as performance practices.

Key takeaways

• Strict ketosis long-term may not suit hard-training athletes, Greenfield argues from his experience
• Cyclic, higher-quality carbohydrate refeeds are presented as a thyroid and hormone support strategy
• Heart plaque claims should be read as one person’s medically supervised case, not a protocol
• Peptide stacks described by influencers are personal experiments, not validated regimens
• Calendared family time and planned rest are framed as recovery tools, not extras
