Epigenetic priming via nutrient deprivation (caloric restriction) in the F0 generation increases the epigenetic plasticity of subsequent generations, allowing them to better adapt to varying diets and metabolic challenges.

Moderate caloric restriction (e.g., 50-70% of normal intake) during early development or pregnancy may 'prime' the epigenome, making offspring more metabolically resilient to future dietary challenges. However, extreme restriction should be avoided as it can lead to growth issues.

Calorie restriction in F0 allowed for increased metabolic health in F2... This study concludes that the calorie restricted diet of F0 primed the epigenome of F1 and F2 to have greater epigenetic plasticity, promoting greater liver metabolic adjustment to varying diets.
