Typical advice for career progression focuses on learning new skills and interview preparation. This is good advice, but in 2019 American businesses lost over $500 billion due to absences and lost productivity due to illnesses.

Put it this way: if you were the boss, would you promote the vibrant, healthy person always delivering good work, or the person with low energy levels, lower productivity, and who takes more sick days?

Unfortunately, 88% of all adults and less than a third of people at a normal weight meet the five standards of optimal metabolic health. Being metabolically unhealthy can lead to:

- Lack of energy, mental fog, tiredness

- Lower productivity levels, making you less effective and less likely to receive promotions

- Decreased quality of professional relationships

- More sick days and absence from work

- Chronic disease

- Lost years of working
