What is the Downside of Heavy Weightlifting on the Keto Diet?
Combining heavy weightlifting with the keto diet may sound like a winning combination for fat loss and muscle gain. However, there are some potential drawbacks to consider:
- Glycogen Depletion: The keto diet drastically reduces carbohydrate intake, depleting glycogen stores in the muscles. Heavy weightlifting relies heavily on glycogen for energy, so performance may suffer.
- Hormonal Imbalances: Weightlifting stimulates the release of hormones such as insulin, growth hormone, and testosterone. The keto diet suppresses insulin production, which can impact hormone levels and muscle growth.
- Increased Muscle Catabolism: When glycogen stores are low, the body may break down muscle tissue for energy (gluconeogenesis). Heavy weightlifting can exacerbate this process, leading to muscle loss.
- Reduced Protein Synthesis: Protein synthesis is essential for muscle growth. The keto diet emphasizes fat intake over protein, which may compromise protein synthesis and limit muscle building.
- Dehydration: The keto diet can lead to dehydration, which can impact performance and recovery from weightlifting.
