Many athletes now seek support from specialist practices such as Nutrition & Co, founded by dietitian Jenaed Ruddock, which focuses on providing evidence-based nutrition support tailored to individual goals, health needs, and performance demands.

This guide explores what sports dietitians do, when athletes should consider seeing one, what qualifications to look for, and how nutrition influences performance. We will also explain why many athletes choose to work with Nutrition & Co and their team of expert practitioners.

What a Sports Dietitian Does

A sports dietitian UK athletes work with specialises in nutrition strategies that support training, performance, recovery, and overall health. Unlike generic nutrition advice found online, sports dietitians provide personalised plans tailored to an individual’s sport, training load, physiology, and goals.

Personalised Nutrition Planning

Every athlete has different nutritional requirements depending on:

• Training intensity and duration

• Sport type (endurance, strength, team sport)

• Body composition goals

• Competition schedules

• Medical history or dietary restrictions

A sports dietitian will assess these factors and develop a plan that ensures athletes are adequately fuelled for both training and recovery.

Performance Nutrition Strategies

Sports dietitians support athletes with practical strategies such as:

• Pre-training and pre-competition fuelling

• In-competition nutrition and hydration

• Recovery nutrition timing

• Energy availability and fuelling strategies

• Body composition management

• Travel and competition nutrition planning

At Nutrition & Co, the team provides tailored strategies through their Adult Nutrition Services and specialist Sports Nutrition support, ensuring athletes receive guidance that fits their training schedules and lifestyle.

Supporting Health as Well as Performance

While performance is important, a qualified sports dietitian will always prioritise long-term health. Poor nutrition practices can lead to issues such as fatigue, hormonal disruption, or injuries related to inadequate energy intake.

Sports dietitians, therefore also help athletes manage:

• Relative Energy Deficiency in Sport (RED-S) risk

• Gastrointestinal issues during exercise

• Injury recovery nutrition

• Immune support during intense training blocks

Practitioners at Nutrition & Co, under the leadership of founder Jenaed Ruddock, take a holistic approach that supports both performance and sustainable health outcomes.

When Athletes Should See One

Many athletes assume sports nutrition support is only necessary for elite competitors. In reality, athletes at all levels can benefit from working with a sports dietitian.

Preparing for a Competition or Event

If you are preparing for an endurance event such as a marathon, triathlon, or cycling race, working with an endurance nutritionist can help you develop an effective fuelling strategy.

Key areas often covered include:

• Carbohydrate loading strategies

• Race-day fuelling plans

• Hydration strategies

• Electrolyte management

• Preventing gastrointestinal discomfort during exercise

Without the right nutrition plan, even well-trained athletes can experience fatigue, energy crashes, or poor recovery.

Improving Training Adaptation

Nutrition plays a key role in how effectively the body adapts to training. Athletes may seek support from a sports dietitian UK when they experience:

• Low energy during training

• Slow recovery between sessions

• Frequent illness or fatigue

• Plateauing performance

A personalised nutrition strategy can help optimise energy availability, macronutrient intake, and recovery timing.

Managing Body Composition

Many athletes want to improve their body composition for performance. However, restrictive dieting can negatively affect performance and health.

Working with a sports dietitian ensures that body composition changes are achieved safely without compromising:

• Training performance

• Recovery

• Hormonal health

• Bone health

At Nutrition & Co, practitioners support athletes through structured and sustainable approaches rather than extreme or restrictive methods.

Returning From Injury

Nutrition plays an important role in injury recovery. Athletes recovering from injury often benefit from support with:

• Protein intake for tissue repair

• Anti-inflammatory nutrients

• Maintaining muscle mass during reduced training

• Gradual return-to-training nutrition strategies

Dietitians can help athletes adjust their nutrition during injury rehabilitation while preparing them for a safe return to sport.

What Qualifications to Look For

Not all professionals offering sports nutrition advice have the same level of training. When choosing a sports dietitian, athletes should look for recognised qualifications and professional registration.

Registered Dietitians

In the UK, the title Dietitian is protected. Registered dietitians must:

• Complete an accredited university degree in dietetics

• Be registered with the Health and Care Professions Council (HCPC)

• Follow evidence-based practice standards

This ensures advice is scientifically grounded and safe.

Sports Nutrition Specialisation

Some dietitians pursue additional training or focus their practice on sports nutrition. This allows them to develop expertise in:

• Endurance sports nutrition

• Strength and power sports

• Team sport nutrition

• Female athlete health

• Performance fuelling strategies

A qualified endurance nutritionist or sports dietitian will understand the unique demands of different sports and training environments.

Evidence-Based Approach

A reputable sports dietitian UK should:

• Use peer-reviewed research

• Avoid fad diets or extreme restrictions

• Provide personalised guidance rather than generic plans

The team at Nutrition & Co, founded by Jenaed Ruddock, emphasises evidence-based advice, ensuring athletes receive nutrition strategies supported by current scientific research.

How Nutrition Impacts Performance

Nutrition is often described as the foundation of athletic performance. Even small improvements in fuelling can significantly impact training adaptation and competition outcomes.

Energy Availability

Athletes require sufficient energy to support both training and normal physiological function. Low energy intake can lead to:

• Reduced performance

• Increased injury risk

• Hormonal disruption

• Poor recovery

A sports dietitian UK helps ensure energy intake matches training demands.

Carbohydrates for Fuel

Carbohydrates are the primary fuel source for moderate- to high-intensity exercise.

Adequate carbohydrate intake supports:

• Endurance performance

• Training intensity

• Glycogen replenishment

An sports dietitian may develop carbohydrate strategies tailored to specific events, such as long-distance running or cycling.

Protein for Recovery

Protein supports:

• Muscle repair

• Muscle adaptation to training

• Recovery between sessions

A sports dietitian UK can help determine optimal protein intake and timing for training goals.

Hydration and Electrolytes

Even mild dehydration can negatively affect performance. Hydration strategies often include:

• Fluid intake before training

• Hydration during longer sessions

• Electrolyte replacement during endurance events

Sports dietitians help athletes develop practical hydration plans tailored to environmental conditions and sweat rates.
