Summary

Two recently published studies have been used by skeptics to claim fasting is pointless.
“You can stop intermittent fasting now,” one sensational headline wrote.

However, there were between-group differences in other important metrics, like glucose, triglycerides and more.

Let's break it down...

Show Notes:

00:45 A year-long TRF study compared caloric restriction with caloric restriction within an early time restricted window of 8 a.m. to 4 p.m. Compliance may have been an issue.
02:05 There was a greater reduction in triglycerides and other proxies of metabolic health early in the study.
04:00 When you eat your last meal is independently correlated with bodyfat percentage. Complete your last meal before 6 hours of the mid-point of your sleep.
05:00 Exercise with time restricted feeding protocols enhance the health benefits.
06:20 Metabolic rate was significantly reduced in participants who continuously restricted their energy intake compared to alternate day fasting participants.
08:55 The study calorie restriction/IF with calorie restriction was conducted during COVID, so some follow up tests were not done.
10:26 This study did not allow participants to select their eating window.
12:53 Fasting may be an easier way for many to get into an energy deficit for weight loss.
14:15 There was a more significant reduction in blood triglycerides in the IF group.
16:05 We need to consider other changes in metabolic parameters, reduction in triglycerides, as well as changes in body composition in study results.

In today's session, let's answer the question.

0:01.8

Is intermittent fasting pointless?

0:03.9

Should you just restrict your calories?

Is there any added benefit to compressing your feeding

window, whether it's early time-restricted feeding

0:10.5

or intermittent fasting compared to just calorie restriction?

0:12.9

We're going to help answer and address that question,

0:15.8

because there's been several recently published studies

0:18.1

that have caused people to question whether or not

0:21.1

there are added health benefits to intermittent fasting

0:23.6

or time-restricted feeding.

0:25.0

Including this recently published study in the New England

0:27.6

Journal of Medicine, the title of this one

0:29.0

was Calorie Restriction with or without time-restricted

0:31.6

feeding in weight loss.

0:33.1

Now, I think this study, this was a year-long study,

0:37.4

and there's some interesting aspects about this

0:39.4

that often haven't been mentioned with regards

0:42.8

to the lay press coverage of these two different studies.

0:46.0

But in brief, this particular study was a year-long,

0:48.6

so it was quite interesting, because this is a long

0:50.7

duration study comparing again, continuous energy restriction
