Abstract

In brief: Preventing hypothermia is crucial to those who work or spend recreation time in cold environments. Adequate energy from the correct proportion of carbohydrates, fats, and proteins can help. Vitamins and minerals are also necessary to prevent nutrition deficiencies and impaired function, but there is no evidence to suggest an increased requirement for them is attributable to cold exposure alone. High protein diets appear to be the worst choice for cold weather work; compared with diets high in carbohydrates or fats, high protein diets increase metabolic water requirements and reduce cold tolerance.

Study Snapshot

High protein diets are not recommended for cold weather work due to increased metabolic water requirements and reduced cold tolerance.

PopulationOlder adults (50-71 years)

Sample size24

MethodsObservational

OutcomesBody Mass Index projections

ResultsSocial networks mitigate obesity in older groups.

Weight loss and changes in body composition at high altitude.

High body fat does not protect against muscle tissue loss at high altitude, and Sherpas do not experience some of the changes affecting Caucasians.

Effects of acute cold exposure on submaximal endurance performance.

Acute cold exposure does not alter aerobic capacity but significantly decreases submaximal endurance performance.

The effects of rest and exercise in the cold on substrate mobilization and utilization.

Exercise in the cold leads to preferential utilization of fat due to reduced skin and core temperatures compared to exercise in a neutral environment.

Metabolic energy expenditure and terrain coefficients for walking on snow.

Energy expenditure increases linearly with increasing footprint depression, with practical limits for prolonged snow walking not exceeding 50% [Vdot]O2max at 20 cm and 10 cm depths without snow shoes.

A marked reduction in calories or protein causes deterioration in physical work capacity in men exposed to severe cold stress.
