An alternative dietary strategy to make weight while improving mood, decreasing body fat, and not dehydrating: a case study of a professional jockey.

The study describes a successful alternative diet and workout strategy for a professional jockey that allowed them to safely reduce weight without dehydration or extreme calorie restriction. This approach also led to better mood and lower body fat percentage.

Introduction and Problem Statement

• The article starts by highlighting the unique challenge for professional jockeys in terms of maintaining weight, as they’re often required to meet specific weight requirements on a daily basis, for most of the year.
• Jockeys often resort to extreme measures like severe dehydration, drastic calorie restriction, and irregular eating intervals to meet these targets, all of which can lead to adverse health consequences.

The Alternative Strategy: Outline and Implementation

• Instead of these harmful practices, the article presents a structured diet and exercise plan that a 22-year-old professional National Hunt jockey used to reduce his weight from 70.3kg to 62.6kg over a period of 9 weeks.
• Prior to starting this regimen, the jockey’s typical daily energy intake was 8.2 MJ, consisting of 42% carbohydrate, 36% fat, and 22% protein, which he consumed in two meals a day.
• During the implementation of the new plan, the jockey’s daily energy intake was equivalent to his resting metabolic rate, split into 6 meals a day, with an altered ratio of 46% carbohydrate, 19% fat, and 36% protein.

Results and Observations

• The combination of adjusted eating patterns and a regular exercise schedule resulted in a total body mass loss of 8kg. His body fat reduced from 14.5% to 9%, all without any intentional dehydration.
• The jockey’s urine osmolality remained within a healthy range, further confirming that the weight loss did not come at the expense of hydration.
• The change in dietary habits also led to improved mood scores, as per the BRUMS scale, suggesting that the approach had a positive impact on mental health as well.

Significance and Conclusion

• All these changes allowed the jockey to meet weight requirements without resorting to dehydration, for the first time in his career. This not only challenges the unhealthy practices prevalent in the sport but also suggests a more sustainable weight management alternative for professional jockeys.
