How to Stay Lean While Travelling for Work

The real protocol

EAA as a snack, paired with some nuts, when a proper meal isn't an option.
Avoid processed food wherever there's a genuine choice.
At restaurants, fish where possible, or a sauce-free steak. Everything grilled, never butter-fried.
Water, roughly 250ml with each meal and between meals.

What happens after the trip

Clients usually come back from a travel week hungrier than usual. Rather than treating that as a setback, it becomes leverage, a chance to push a bit more food and a bit more benefit the following week. Every occasion, including the disruption itself, gets turned into an advantage rather than something to recover from.
