Late night eating can trigger hypertension and prediabetes. A study conducted by US scientists on 12,708 people has revealed that people who ate late had higher odds of hypertension and prediabetes compared with those who ate less in the evening. The study was conducted on Hispanic and Latino people between 18 and 76 years of age.
Late eaters had higher levels of fasting glucose (93.7 versus 93.0 mg/dL; P=0.001), insulin glucose levels (12.4 versus 11.6 mU/L; P=0.003), score on the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR; 2.9 versus 2.7; P=0.001), systolic blood pressure (BP; 118.7 versus 117.5 mm Hg; P=0.004), diastolic BP (72.2 versus 71.0 mm Hg; P<0.0001).
The study revealed that eating in the evening was not associated with overweight, obesity, or central adiposity. The study pointed out that people who consumed at least 30% of their energy after 6 pm had 23% higher odds of hypertension (OR 1.23, 95% CI 1.05-1.44) and 19% higher odds of prediabetes (OR 1.19, 95% CI 1.03-1.37) compared with those who ate less in the evening.
The study, led by Nour Makarem, PhD. at Columbia University in New York City, highlighted that none of the participants had cancer or diabetes. Of these participants, the average daily energy intake was 35.7% after 6 pm, and more than half reported eating at least 30% of energy after 6 pm.
The researchers have stressed that eating at unconventional circadian times is associated with adverse metabolic effects.
