Forget the diets - they are pointless without blood work - do this instead (it’s free).
We have found that over 90% of people are guessing wrong.
Taking supplements they don’t need.
Eating the way someone else’s body was designed to eat not theirs.
Training, or should I say overtraining based on where their stress levels are.
Keep it simple until you have the facts, the data, and a complete look under the hood.
