What should a CEO eat at client dinners and airports?

Protein first, every time. At a client dinner order the protein, eat it first, add vegetables and treat bread and dessert as optional. At an airport, find one real protein source rather than snacks. Aim for 1.8 to 2.2 grams of protein per kilo of bodyweight a day, across three meals. No counting at the table.

The plate order

Protein first on the plate, physically first. Vegetables second. Carbohydrate third, if at all. That one rule works in any restaurant, any city, any menu, without anyone at the table noticing.

A protocol that cannot survive a client dinner is not a protocol. It is a countdown. You should never become the person counting calories at the table.

Short answers

How much protein does an executive need?

The working target is 1.8 to 2.2 grams per kilo of bodyweight a day, split across three meals. If you have a kidney condition or another medical reason to watch protein, check with your doctor first.

Do I have to stop drinking?

No. Decide before the evening, not during, and keep the last drink at least three hours before bed. The effect on sleep is usually the bigger cost than the drink itself.

Should I count calories when I travel?

No. Hit the protein and the food quality and the rest follows. Counting at the table is the kind of rule that collapses by the third trip.

Three sharp questions, a straight read on the pillar costing you the most, and an honest answer on fit, both directions. If it is a wrong fit I say so and point you somewhere better.

Fifteen minutes. Three sharp questions. A straight read and a clear next step, either way.

Why am I exhausted as a CEO even though I sleep seven hours? How should a founder who travels constantly keep training? What is the minimum exercise a busy executive needs to stay healthy for the next 20 years? How do executives fix their sleep without supplements or wearables? All answers →

Educational, not medical advice. If you have a diagnosed condition, symptoms that worry you, or are under a doctor's care, speak to your doctor before changing how you train, eat or sleep.
