The Viral Diet That Shook the NFL World
In early 2022, NFL wide receiver DK Metcalf appeared on Kevin Garnett's podcast, "KG Certified," and delivered a bombshell revelation about his daily nutrition. The physically imposing athlete claimed that his diet consisted of just a morning coffee, several bags of gummy candy in the afternoon, and a single dinner meal. He described his routine: a double workout, followed by a trip to Starbucks for coffee, with candy holding him over until his late-evening meal. This diet quickly became a viral sensation, dividing fans and nutrition experts alike. Some marveled at his ability to maintain a world-class physique and performance on what seemed like a child's menu, while others expressed deep skepticism and concern.
The Science Behind the Skepticism
For a professional athlete like Metcalf, who stands at 6-foot-4 and weighs around 235 pounds, the caloric and nutritional demands are immense. A typical NFL player requires thousands of calories per day, primarily from protein and complex carbohydrates, to fuel intense training, explosive movements, and proper recovery. Metcalf's original claimed diet flew in the face of established sports nutrition principles. Experts and fans questioned how he could possibly meet his body's needs for essential nutrients and muscle repair with such a limited intake.
- Energy Deficit: While Metcalf's approach, a form of intermittent fasting known as OMAD (One Meal a Day), can lead to weight loss, it's generally not recommended for elite athletes who need to maintain muscle mass and energy reserves.
- Macronutrient Imbalance: Relying on candy for energy provides simple sugars that lead to energy spikes and crashes, not the sustained fuel needed for peak athletic performance. Candy lacks the protein necessary for muscle protein synthesis and repair.
- Injury Risk: An NFL nutritionist criticized the high-sugar, low-protein regimen, noting it could increase the risk of injury due to insufficient nutritional support for daily wear and tear.
The Shift to a More Balanced Approach
Faced with public scrutiny and the realities of his demanding career, Metcalf has since modified his extreme eating habits. In July 2024, he revealed that he had shifted his routine.
“I eat twice a day now,” Metcalf told K5 Sports. “I’ve slowed down on the coffee and candy.”
This update provided some relief to worried fans and parents, many of whom voiced concerns that their children were emulating the unusual diet. Metcalf even apologized to parents, clarifying that his previous diet was a personal choice, and likely not one that others could or should replicate. His decision to incorporate a second meal and reduce his intake of sugar indicates a move toward a more sustainable and nutritionally sound eating plan, aligning more closely with standard advice for high-performance athletes.
Comparison: Metcalf's Old Diet vs. New Diet
| Dietary Aspect | Original Viral Diet (2022) | Updated Diet (2024) | Rationale for Change | Importance for Performance |
|---|---|---|---|---|
| Meal Frequency | One meal per day (OMAD) | Two meals per day | Provides a more consistent energy supply throughout the day, avoiding large spikes and crashes. | Crucial for sustained energy during practice and games and for optimal recovery. |
| Carbohydrate Source | Bags of gummy candy | Reduced candy intake; presumably replaced with more complex carbs. | Shifts from simple, high-sugar carbs to nutrient-dense options that provide steady fuel. | Stabilizes blood sugar and prevents fatigue. |
| Protein Intake | One large dinner meal | Two meals likely contain more consistent protein distribution throughout the day. | More consistent protein intake supports muscle protein synthesis and repair, essential for maintaining mass. | Prevents muscle atrophy and aids recovery. |
| Fluid Intake | Coffee and water | Reduced coffee intake, implied continued focus on hydration. | Less reliance on caffeine for energy, promoting natural energy levels and better sleep. | Vital for hydration, temperature regulation, and overall cellular function. |
The Takeaway: Extreme Diets and Elite Athletes
The story of DK Metcalf’s evolving diet serves as a powerful reminder that what works for one individual, particularly a genetically gifted athlete, may not be sustainable or healthy for others. While Metcalf's initial success with a highly unconventional diet was remarkable, the fact that he has since moved to a more balanced approach reinforces the long-held wisdom of sports nutrition. Elite performance typically requires a consistent and balanced intake of high-quality macronutrients, not just a single, large meal.
Can DK Metcalf Really only eat one meal a day? Conclusion
In conclusion, based on his own statements, DK Metcalf no longer follows the viral one-meal-a-day diet. While he did adhere to this practice for some time and saw success, he has publicly acknowledged shifting to a more standard two-meal-a-day plan. This change was a result of public backlash and potential long-term health concerns. The episode highlights the importance of evidence-based nutrition, even for individuals with elite genetics, and serves as a cautionary tale against replicating extreme diets without professional guidance. What appears to work for an outlier athlete is not a reliable blueprint for the general population.
