Eating Late at Night Is Not a Good Idea. This Experiment Reveals
Why
It's long been popular advice for people looking to lose weight to avoid late
night snacking. It's no wonder, with a host of research showing that late night
eating is linked to greater body weight and increased risk of obesity. But until
now, few studies have actually investigated precisely why late night eating is
linked to greater body weight. This is what a
recent US study set out to
uncover. They found that eating four hours later than normal actually
changed many of the physiological and molecular
mechanisms that favor
weight gain.
This work adds to other recently published work which has found that eating
earlier in the day is more beneficial for both appetite and body weight
control.
Late eating
To
conduct their study, the researchers had 16 participants follow two
different meal schedules, each for a period of six days total. The first protocol
had participants eat their meals early in the day with the last meal consumed
approximately six hours and 40 minutes before bedtime. The second
protocol had participants eat all of their daily
meals approximately four
hours later. This meant they skipped breakfast and instead had lunch, dinner
and an evening meal. Their last meal was consumed only two and a half
hours before sleep.
The study was conducted in a controlled lab, which ensured the participants
in each group consumed an identical diet, and that all of their meals were
evenly spaced with around four hours between them. To understand how late
eating affected the body, the researchers specifically looked at three different
measures which are associated with weight gain:
1.
The influence of appetite,
2. The impact of eating time on energy expenditure (calories burned), and
3. Molecular changes from fat tissue.
Appetite was measured using two techniques. The first technique was having
