8-hour time-restricted eating linked to a 91% higher risk of cardiovascular death

[LiberalArkie]

Research Highlights:

A study of over 20,000 adults found that those who followed an 8-hour time-restricted eating schedule, a type of intermittent fasting, had a 91% higher risk of death from cardiovascular disease.
People with heart disease or cancer also had an increased risk of cardiovascular death.
Compared with a standard schedule of eating across 12-16 hours per day, limiting food intake to less than 8 hours per day was not associated with living longer.

CHICAGO, March 18, 2024 — An analysis of over 20,000 U.S. adults found that people who limited their eating across less than 8 hours per day, a time-restricted eating plan, were more likely to die from cardiovascular disease compared to people who ate across 12-16 hours per day, according to preliminary research presented at the American Heart Association’s Epidemiology and Prevention│Lifestyle and Cardiometabolic Scientific Sessions 2024, March 18- 21, in Chicago. The meeting offers the latest science on population-based health and wellness and implications for lifestyle.

Time-restricted eating, a type of intermittent fasting, involves limiting the hours for eating to a specific number of hours each day, which may range from a 4- to 12-hour time window in 24 hours. Many people who follow a time-restricted eating diet follow a 16:8 eating schedule, where they eat all their foods in an 8-hour window and fast for the remaining 16 hours each day, the researchers noted. Previous research has found that time-restricted eating improves several cardiometabolic health measures, such as blood pressure, blood glucose and cholesterol levels.

“Restricting daily eating time to a short period, such as 8 hours per day, has gained popularity in recent years as a way to lose weight and improve heart health,” said senior study author Victor Wenze Zhong, Ph.D., a professor and chair of the department of epidemiology and biostatistics at the Shanghai Jiao Tong University School of Medicine in Shanghai, China. “However, the long-term health effects of time-restricted eating, including risk of death from any cause or cardiovascular disease, are unknown.”

Question: True?

1. "My miracle is that when I feel hungry I eat, and when I feel thirsty I drink."

When Bankei was preaching at Ryumon temple, a Shinshu priest, who believed in salvation through the repetition of the name of the Buddha of Love, was jealous of his large audience and wanted to debate with him.

Bankei was in the midst of a talk when the priest appeared, but the fellow made such a disturbance that Bankei stopped his discourse and asked about the noise.

"The founder of our sect," boasted the priest, "had such miraculous powers that he held a brush in his hand on one bank of the river, his attendant held up a paper on the other bank, and the teacher wrote the holy name of Amida through the air. Can you do such a wonderful thing?"

Bankei replied lightly: "Perhaps your fox can perform that trick, but that is not the manner of Zen. My miracle is that when I feel hungry I eat, and when I feel thirsty I drink."

3. I'll eat when I'm hungry, I'll drink when I'm dry...

If the moonshine don’t kill me
I’ll live til I die.

2. Wonder why study was embargoed until 3 pm?

Not familiar with that terminology being used with regard to a medical study.

I lost about 20 pounds over several months on a less strict version of intermittent fasting. It was easier to eat less following this kind of system. Wonder if other studies have been done. Further investigation required I guess...thx.

4. I restrict my time eating and I'm a healthy 84 year old. I stop eating after dinner (around 7 or 7:30 pm) and do not eat

again until breakfast around 7 am. If I'm not hungry, why would I eat?

6. It sounds as if you are following the standard schedule of 12-16

Hours rather than what they consider to be restricted, which is 8 hours.

11. Oops, forgot to mention my ice cream bar in mid afternoon...my little treat...

[spooky3]

12. Hee hee! Nt

[CTyankee]

14. I swear I don't know how that happened...

5. I'll wait till more information comes out on the topic. I'm having a hard time finding information on this..nt

7. I just read this and thought, "I should probably have a snack . . ."

I've been doing 16/8 on and off for awhile. Conscientiously for probably the last six months. I naturally incline toward it anyway, since half the time I have a 16 oz coffee I sip all morning before getting actually hungry around noon. Right now, it's 1:40pm, and I just realized I haven't eaten yet today.

Welp.

It's one study, but 20,000 people. I'll have to dig into it. Because there's a question in who's doing it. I read through and saw the cancer patients and heart disease people. But I'm thinking more along the lines of obesity, pre-diabetic, etc. The average age in the study is 49. By then, people can often have pre-existing problems. Are those people more likely to actively seek to do 16/8 to improve health than people who are already relatively healthy/fit?

But . . . I think I'll go make some tuna anyway.

8. Fasting is hell on the gallbladder.

"Your gallbladder releases bile each time you eat. When you skip meals, those bile juices build up. This raises the cholesterol levels in your gallbladder. Over time, the waxy fats can harden into gallstones. Some bile acids also may make you more likely to get gallbladder cancer."

9. A percentage represents "relative risk"

and is therefore essentially meaningless unless they disclose "absolute risk". For example, if two people out of a hundred in one group develop a malady but only one out of a hundred in the other group that's a 100% difference, but statistically insignificant in an absolute sense. We need to know the "absolute" data.

10. That is counterintuitive.

If the fasting improves blood pressure, blood glucose, cholesterol and weight, then it seems odd that the risk of cardiovascular disease would go up.

Even before intermittent fasting became “a thing”, my usual meal times fit within a 10 hour window—unless a small handful of peanuts before bed counts, which bumps it up to 14 hours.

13. Do We Know

that fasting has any effect on blood pressure, blood glucose, cholesterol and weight? Like actual scientific proof?
