Nutrition Scientist Sarah Berry Describes Three Diet Adjustments for Metabolic and Cardiovascular Health

Sarah Berry, a professor and nutrition scientist specializing in cardiovascular health, has modified her eating habits in response to emerging research. The research examines how the timing and speed of eating may influence metabolic and cardiovascular health. Berry shared these changes in an interview with Business Insider.

Berry focuses on a balanced diet that includes whole foods and avoids refined sugar. She has recently incorporated specific tweaks to her routine. , fasting for 12 hours overnight, and eating food at a reasonable pace.

Not Eating After 9 p.

m. , despite her tendency to snack. Research indicates that late eating can disrupt the circadian rhythm, which regulates sleep, hormones, and hunger. This disruption may affect metabolic health and increase risks of diabetes and cardiovascular disease.

Studies show that eating late can lead to waking up hungry, potentially causing weight gain. A 2022 meta-analysis in Obesity Reviews found that consuming most daily calories earlier in the day resulted in greater weight loss compared to later consumption. Earlier eating was linked to lower LDL cholesterol, lower fasting glucose, and reduced insulin resistance.

12-Hour Overnight Fast Berry maintains a 12-hour fast from 9 p.

m. m. This practice is a form of intermittent fasting within a restricted eating window. Longer fasts of about 24 hours may trigger autophagy, a cellular process that recycles damaged parts and optimizes cell function.

Research suggests autophagy could help prevent heart disease and cancer, though most evidence comes from animal studies. Human studies are needed to confirm these effects. Berry noted that restrictive eating rules may pose risks for individuals with a history of disordered eating.

Eating at a Reasonable Pace Berry chews her food slowly to avoid eating too quickly.

Rapid eating has been associated with poorer metabolic biomarkers. A 2021 meta-analysis in Frontiers in Nutrition, involving 465,155 participants, linked fast eating to higher risks of metabolic syndrome, obesity, elevated blood pressure, low HDL cholesterol, and elevated blood sugar. These factors are risk indicators for cardiovascular disease.

Berry stated that eating too fast often leads to overconsumption. The changes she made are based on current research into eating patterns and health outcomes. The stakes involve potential improvements in metabolic health for individuals who adopt similar habits.

Affected groups include those at risk for chronic diseases. Further research is required to establish long-term effects in humans.
