The Claim

Two recreational cyclists on plant-based diets maintained body weight and fat-free mass during a 30-day, 4300-km cross-Canada ride despite high energy expenditure, with one cyclist losing 2.3 kg of fat mass and gaining 1.4 kg of fat-free mass while consuming over 2.3 g/kg/day of protein.

Description
1 study reviewed
In plain English

Two recreational cyclists following a plant-based diet maintained their overall body weight and muscle mass during a 30-day, 4300-km cycling trip across Canada, despite high energy expenditure; one cyclist lost 2.3 kilograms of fat and gained 1.4 kilograms of muscle while consuming more than 2.3 grams of protein per kilogram of body weight daily.

See the scientific wording

Two recreational cyclists on plant-based diets maintained body weight and fat-free mass during a 30-day, 4300-km cross-Canada ride despite high energy expenditure, with one cyclist losing 2.3 kg of fat mass and gaining 1.4 kg of fat-free mass while consuming over 2.3 g/kg/day of protein.

Why this might work

Eating a lot of plant-based protein every day keeps muscles from breaking down during long, intense rides, while the body burns fat for energy instead of muscle, allowing fat loss and muscle gain even when burning huge amounts of calories.

  1. Study: Energy balance in cyclists on plant‐based diets during a 30‐day, 4300‐km ride across Canada: Two case studies

    Two regular cyclists ate only plant-based food and rode across Canada for 30 days, burning tons of calories — yet one lost fat and even gained a little muscle, without losing any muscle mass. This shows it’s possible to stay strong and lose fat on a plant-based diet, even during extreme exercise.
