The timing of food intake might affect your weight loss efforts!

OK guys, first of all, I am sad to say that I missed the symposium on alternate-day fasting at Obesity Week! I know I talked it up last week, so I feel terrible that I can’t report back to you about it this week. I was so upset — I (and many others) kept wandering around the area where it was *supposed* to be held, only to fail to find it. So I can’t tell you yet what was presented there — I’ll have to wait until the audio and slides become available for me to view online next month.

BUT. I *did* attend a symposium that dealt with the timing of food intake in a slightly different way, and discovered something new: that increasing your calories at breakfast and decreasing your calories at dinner might have a significant impact on your weight loss success! A study just published in July in Obesity examined the effects of two parallel diet groups: each group ate 1400 kcal per day for 3 months, but the first group ate most of their calories in the morning (700 kcal at breakfast, 500 kcal at lunch, and just 200 kcal at dinner), while the second group ate a more traditional American pattern with the most energy intake in the evening (200 kcal at breakfast, 500 kcal at lunch, and 700 kcal at dinner).


You can read the study itself here.

The results were striking: the big-breakfast group lost more weight, more inches off their waists, had greater improvements in insulin and fasting glucose levels, and even had drops in their triglyceride levels (while the big-dinner group’s triglycerides actually increased). Perhaps most importantly, the mean satiety scores were significantly higher in the big-breakfast group, and hunger scores were lower — so they felt more satisfied on the same amount of calories! Food for thought….
