Energy intake, weight, and body composition of Canadian soldiers participating in an Arctic training
Military training in extreme environments increases weight loss risk, which could affect soldiers’ performance. This study aimed to assess daily energy intake and requirements of Canadian Armed Forces soldiers consuming combat rations over an 8-week Arctic training and document impact on weight and...

Weight loss was measured (3.9±3.0 kg) for 12 participants from beginning to mid-training after a week consuming combat rations. Energy intake on rations was lower than estimated daily energy requirements and resulted in energy deficits (49.8±19.2%). No body composition changes were measured.
