Some value given
  1. On fish oil, he says too much made him feel 'floaty', and he now aims for a balance between a flexible and a sturdy cell membrane. He looks for triglyceride (TG) form on the label.
  2. On creatine, he says low doses still have a place for a mild focus effect, but he felt a big jump in strength and energy at higher daily amounts. Early water retention faded for him after about a month.
  3. On fasting, he prefers 'burst fasting': 18 hour fasts on 3 or 4 straight days, then 4 or 5 days off, because random fasts felt too jarring for his body.
  4. He now rotates green tea and coffee every 2 days so neither stops working for him, and he's back to daily red light sessions.
  5. He stopped fasting on his most stressful days and stopped toughing out jet lag. He'll use a small dose of melatonin for a night or two when sleep matters.

What changed his mind on fish oil, creatine and fasting?

He hasn't thrown out his old advice. He now uses a standard fish oil instead of mega dosing, takes more creatine than the low doses he used to suggest, and does fasts on 3 or 4 days in a row followed by several days off, instead of scattered one-off fasts.

Worth watching?Some value given. A fast list of course corrections from someone who tests things on himself. The first three (fish oil, creatine, fasting) carry the video. The rest are shorter personal notes, plus a sponsor read in the middle.

Actionable

  • If you fast, try grouping fast days together for a week and compare how you feel against random fast days.
  • Rotate your caffeine source every couple of days if your usual one stops doing much.
  • Look at the label form on your fish oil (TG vs ethyl ester) before buying the next bottle.
  • Put 2 days a week of lifting only on your calendar, with no cardio, if your strength has stalled.
  • Skip fasting on days you're already stressed or run down.

Lessons

  • Changing your mind in public is a strength. He frames each change as a course correction, and says to keep anything that's working for you.
  • More isn't always better. Both his fish oil and his intense training swung too far before he pulled back.
  • Easy aerobic work is a base to add to hard sessions, and he says he made the mistake of doing one or the other.
  • Letting go of the illusion of control, he says, was the biggest change in his life, and it made discipline feel easier.
