As in, an eight- to 12-hour window.
WWE champion wrestler Bianca Belair has been upfront about her former challenges with night eating. "I ended up having this obsession with food where I was binge eating at night and I was gaining all this weight," she admits. In the ring and in her life, she's discovered that timing matters — that when you eat is just as important as what you eat.
There are wide-ranging, disease-fighting benefits from limiting your food intake to the hours the sun is shining as well as eating the majority of calories before 3 p.m. That's because the sun positively influences how a variety of your hormones work.
A lab study out of the University of Kentucky indicates that if you have type 2 diabetes, restricting mealtimes to an eight- to 12-hour window — say 9 a.m. to 7 p.m. — may help prevent blood pressure from staying high overnight. Blood pressure in healthy people goes down while they sleep, but there's often no dip for people with diabetes. And high blood pressure is associated with increased risk of cardiovascular disease, stroke and heart attack.
So if you have diabetes, it may be helpful to follow your body's circadian rhythm for food and influences your blood pressure's circadian rhythm. That's because when you eat affects a cascade of hormones and other bioactive chemicals that affect your metabolism as well as blood vessel dilation or constriction, respiration and heart beat.
