When untrained guys eat a high-fat diet for 7 weeks, their bodies get better at using fat from the blood as fuel during exercise, saving their sugar stores.
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.

When your body gets used to burning fat for fuel, it becomes better at using fat by turning up the systems that break it down and use it for energy.
If untrained guys eat a high-fat diet for 7 weeks, their bodies get better at burning fat from the blood during exercise compared to eating a high-carb diet.
If untrained guys eat a high-fat diet for 7 weeks, they burn more fat during exercise than if they eat a high-carb diet.
If untrained guys eat a high-fat diet for 7 weeks, their muscles use less stored sugar during medium-intensity exercise compared to eating a high-carb diet — it’s like saving their fuel — but their legs still take up the same amount of glucose from the blood.
