The claimWhat Mike actually said
Tyson adopted a vegan diet years ago and has publicly promoted it, describing more stamina, a clearer positive mindset, and feeling less 'weighed down' than when he ate meat. His account is personal and enthusiastic rather than clinical.

- Dinu et al., Crit Rev Food Sci Nutr, 2017, meta-analysis linking vegetarian/vegan diets to lower LDL cholesterol and body weight
- Lynch et al., Nutrients, 2018, review finding plant-based diets show no clear advantage or disadvantage for exercise performance
Why it mattersWhy this matters for longevity
Personal 'I feel amazing' testimonials drive diet trends far more than the modest, measurable effects trials actually find.
A poorly planned vegan diet can fall short on protein, B12, and iron, which affects energy rather than boosting it.
The evidenceWhat the science says
Meta-analyses show vegetarian and vegan diets can lower LDL cholesterol and body weight, real cardiometabolic benefits.
A controlled review of plant-based diets and exercise found no clear performance advantage or disadvantage, and there is no reliable evidence they deliver the stamina or mood surge Tyson reports.
TakeawayThe honest takeaway
The practical lesson
A well-planned vegan diet is reasonable for heart health, but do not expect a guaranteed jump in energy or stamina.

SupplementsThe supplement angle: Vitamin B12, iron, and protein
Support a habit, do not replace one
Vegans commonly need vitamin B12 and should watch iron and protein intake, since shortfalls can sap the very energy the diet is meant to boost. A clinician can advise on testing and supplements.
Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
