Dr. Milo Wolf Highlights the Benefits of Consuming Carbohydrates Before Workouts
# Dr. Milo Wolf Discusses the Importance of Carbohydrates Before Workouts
Many weightlifters may focus intently on their training routines but often overlook the importance of pre-workout nutrition. Dr. Milo Wolf, a sport scientist and natural bodybuilder, believes this oversight can hinder performance and muscle growth over time.
In a recent YouTube video, Wolf presented new research on pre-workout carbohydrates, explaining how consuming carbs before exercising can enhance workout quality, especially during longer and more intense sessions.
## New Research Supports Pre-Workout Carbs
Wolf referred to a 2026 meta-analysis that reviewed 30 studies on resistance training performance. The results indicated that eating carbohydrates before exercising led to a small yet significant improvement in workout performance. While one workout may not dramatically alter physique, Wolf stressed the cumulative effect of consistently improved training sessions.
“One session won’t change your physique, but hundreds of slightly better sessions just might,” he said. These minor performance gains can accumulate over months and years of training.
## Why Do Carbs Improve Performance?
Wolf described four main reasons pre-workout carbohydrates might boost performance:
1. **Carbs Signal the Brain**
Research has shown that merely rinsing the mouth with carbohydrates can enhance performance. The mouth recognizes carbohydrates and sends signals to brain regions linked to reward and motor control. A 2025 meta-analysis found that carbohydrate mouth rinsing improved strength training performance across 24 studies, indicating a positive brain response even before carb digestion.
2. **Reduced Hunger**
Training on an empty stomach can harm performance. Wolf cited studies showing that athletes who had breakfast before workouts accomplished more squat repetitions than those who only consumed water. Other research confirmed that reducing hunger can enhance workout performance, even if calorie intake remains constant. “Don’t start training hungry,” Wolf advised.
3. **Improved Blood Glucose Availability**
Consuming carbohydrates before training elevates blood glucose levels, allowing working muscles to use this energy during intense workouts, thereby supporting performance and output.
4. **Preserving Muscle Glycogen**
While resistance training doesn’t deplete glycogen as much as endurance activities, some fast-twitch muscle fibers can still experience significant glycogen depletion. Studies reveal that certain fibers lose over 50% of their glycogen during intense workouts, notably those responsible for strength and muscle growth.
## When Carbs Matter Most
The study results suggest that carb benefits are especially evident during:
- Longer workouts
- Higher-volume training sessions
- Higher-repetition workouts
- Programs focused on muscle growth
- CrossFit-style conditioning sessions
- Challenging lower-body sessions
## Practical Carb Recommendations
Wolf recommends consuming carbohydrates from immediately before a workout up to two hours in advance. For most workouts, he suggests:
- **0.3 to 0.6 grams of carbohydrates per kilogram of body weight**
For longer or more demanding sessions, particularly leg workouts, he advises:
- **0.8 to 1.2 grams of carbohydrates per kilogram of body weight**
Fruits, sports drinks, and other easily digestible carbohydrate sources can be effective options based on timing and individual preferences.
## The Takeaway
Wolf asserts that most lifters would likely see improved performance by including carbohydrates before workouts. Although the boost may seem modest for a single session, consistently better training quality can contribute to greater muscle growth and improved long-term results.
