Some research has shown that dieters who eat most of their calories earlier in the day lose more weight than those who eat their big meal at the end of the day.
Just one study is mentioned below. (There are others mentioned in the article.)
The following is a direct quote of just one study cited in USNews & World Report by
Tamara Duker Freuman, MS, RD, CDN, a registered dietitian whose NYC-based clinical practice specializes in digestive disorders, celiac Disease, and food intolerances. Her personal blog, www.tamaraduker.com, focuses on healthy eating and gluten-free living.
"Take, for example, the small but fascinating 2013 study published in the journal Obesity, in which close to 100 overweight and obese women consumed an identical number of calories – 1,400 per day – for three months."
"One subset of these women had their calories front-loaded to the early part of day, with 700-calorie breakfasts, 500-calorie lunches and 200-calorie dinners."
"The remaining group of women followed the opposite pattern, consuming half their daily calories at dinner – which consisted of the identical 700-calorie meal the other participants ate for breakfast."
"The 700-calorie meal, moreover, always included a sweet dessert, such as a cookie or piece of cake. "
"Both groups of women lost weight, but the big-breakfast eaters lost significantly more weight (10 pounds more on average) and inches off their bellies (1.5 inches more on average) compared to the big dinner eaters – despite consuming the exact same number of total calories daily!"
"They also had greater improvements in metabolic health markers, such as insulin levels and triglycerides, compared to the big dinner eaters. "
"While this study's implications are limited by the fact that it was small, included only women and lasted a relatively short period of time, its findings nonetheless provide some pretty clear support to the hypothesis that the timing of our calorie intake matters in addition to the amount of our calorie intake. Or – that when we eat matters, too."
