Discover the Surprising Truth About Building Muscle: Keto vs. Low-Carb Diets – Which is More Effective?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Understand the difference between keto and low-carb diets | While both diets restrict carbohydrate intake, keto is a more extreme version of low-carb that emphasizes high fat intake and very low carbohydrate intake. Low-carb diets typically allow for more flexibility in macronutrient ratios. | Both diets can be difficult to sustain long-term and may require significant changes to eating habits. |
| 2 | Consider the impact on muscle protein synthesis | Both keto and low-carb diets can impact muscle protein synthesis, which is the process by which muscles repair and grow after exercise. Low-carb diets may reduce muscle protein synthesis, while keto diets may increase it. | It is important to ensure adequate protein intake regardless of diet type to support muscle development. |
| 3 | Evaluate insulin sensitivity | Insulin sensitivity refers to the body’s ability to respond to insulin and regulate blood sugar levels. Low-carb diets may improve insulin sensitivity, while keto diets may have a more mixed impact. | Individuals with insulin resistance or diabetes should consult with a healthcare provider before starting a low-carb or keto diet. |
| 4 | Consider the impact on gluconeogenesis | Gluconeogenesis is the process by which the body produces glucose from non-carbohydrate sources. Keto diets rely heavily on gluconeogenesis to provide energy, while low-carb diets may rely more on glycogen stores. | Individuals on a keto diet may experience increased gluconeogenesis, which can impact muscle development and overall energy levels. |
| 5 | Evaluate fat adaptation | Fat adaptation refers to the body’s ability to use fat as a primary fuel source. Keto diets emphasize fat adaptation, while low-carb diets may allow for more flexibility in fuel sources. | Fat adaptation can take time and may impact athletic performance during the adaptation period. |
| 6 | Consider the impact on glycogen depletion | Glycogen is the stored form of glucose in the body, and is a primary fuel source during exercise. Low-carb diets may deplete glycogen stores more quickly, while keto diets may rely less on glycogen for energy. | Individuals on a low-carb diet may need to adjust their exercise routine to account for glycogen depletion. |
| 7 | Evaluate the anabolic response | Anabolic response refers to the body’s ability to build muscle tissue. Both keto and low-carb diets can impact the anabolic response, with keto diets potentially having a more positive impact. | Adequate protein intake and exercise are still key factors in maximizing the anabolic response regardless of diet type. |
| 8 | Consider metabolic flexibility | Metabolic flexibility refers to the body’s ability to switch between different fuel sources. Low-carb diets may improve metabolic flexibility, while keto diets may limit it. | Individuals on a keto diet may experience difficulty switching to carbohydrate-based fuel sources during high-intensity exercise. |
| 9 | Evaluate nutrient partitioning | Nutrient partitioning refers to how the body allocates nutrients for different purposes, such as energy production or muscle development. Both keto and low-carb diets can impact nutrient partitioning, with keto diets potentially having a more positive impact on muscle development. | Adequate protein intake and exercise are still key factors in maximizing nutrient partitioning regardless of diet type. |
| 10 | Consider the thermic effect | The thermic effect refers to the energy required to digest and process food. Protein has a higher thermic effect than carbohydrates or fat. Both keto and low-carb diets may increase the thermic effect, with low-carb diets potentially having a more positive impact. | Adequate protein intake is still key in maximizing the thermic effect regardless of diet type. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Keto and low-carb diets are the same thing. | While both diets involve reducing carbohydrate intake, keto is a more extreme version of low-carb that involves consuming very few carbs (usually less than 50 grams per day) and high amounts of fat to induce ketosis. Low-carb diets may allow for slightly higher carb intake and do not necessarily require such high levels of fat consumption. |
| Carbs are necessary for muscle development. | While carbohydrates can provide energy for workouts, they are not essential for building muscle. Protein is the most important macronutrient for muscle growth, as it provides the amino acids needed to repair and build new muscle tissue. Fat can also be used as an energy source during exercise on a low-carb or keto diet. |
| A high-protein diet will kick you out of ketosis. | Consuming too much protein can potentially lead to gluconeogenesis (the conversion of protein into glucose), which could raise blood sugar levels and kick someone out of ketosis if they consume too many carbs overall in their diet as well. However, moderate protein intake (around 1 gram per pound of body weight) should not significantly impact ketone production or cause issues with staying in ketosis while still allowing adequate protein intake for muscle development. |
| You need carbs to fuel your workouts on a low-carb or keto diet. | Initially, transitioning from a carb-heavy diet to one with fewer carbs may result in decreased performance during intense exercise due to lower glycogen stores in muscles; however, over time the body adapts by becoming more efficient at using stored fat as fuel instead of relying solely on carbohydrates during exercise. |
| Eating too much fat will make you gain weight even if you’re following a low-carb or keto diet. | While it’s true that eating excess calories from any macronutrient can lead to weight gain, consuming healthy fats (such as those found in avocados, nuts, and olive oil) in moderation on a low-carb or keto diet can actually aid in weight loss by keeping you feeling full and satisfied. Additionally, fat is important for hormone production and overall health. |
