Two groups of middle-aged men who lift weights ate different low-carb diets while eating fewer calories. One ate keto (high fat, very low carb), the other ate low-carb but not keto.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Among middle-aged men who lift weights and are eating fewer calories, a ketogenic diet that keeps ketones high does not lead to better preservation of muscle strength or body composition than a non-ketogenic low-carb, high-fat diet over eight weeks.
Among middle-aged men who lift weights and eat fewer calories, levels of testosterone rise and insulin levels fall, whether they follow a ketogenic diet or a different type of low-calorie diet.
For middle-aged men who lift weights and are eating fewer calories, switching between a low-carb ketogenic diet and a higher-carb diet does not change their blood fat levels or blood sugar levels.
In men with body fat below 10% and women with body fat below 20%, levels of hormones that support muscle growth and tissue repair are consistently lower than in individuals with higher body fat.
