Time-Restricted Eating Plus Tai Chi Improved Cholesterol in Menopause: What the Research Shows

Time-Restricted Eating Plus Tai Chi Improved Cholesterol in Menopause: What the Research Shows

Researchers put 142 postmenopausal women, ages 50 to 60, into three groups for 8 weeks. One group ate only within an 8-hour window each day and also did Tai Chi three times a week. That group had the biggest drop in "bad" cholesterol and the best improvement in blood vessel health, more than eating-window fasting alone.

The Short Version

• What they tested: Whether eating only within an 8-hour window, plus Tai Chi, beats the eating window alone for cholesterol and blood vessel health after menopause.
• Who did it: Wang XY and colleagues at Hangzhou Normal University, China, published in the Journal of the International Society of Sports Nutrition in 2025.
• How many people: 142 women, all past menopause, ages 50 to 60.
• How long: 8 weeks.
• What happened: The group combining fasting with Tai Chi had the largest drop in "bad" cholesterol and the best improvement in blood vessel flexibility.

What They Wanted to Find Out

After menopause, women face a higher risk of heart and blood vessel problems. Researchers wanted to know if eating only within an 8-hour window each day could help. They also wanted to see if adding a gentle exercise, Tai Chi, made the fasting work even better.

This builds on other work in this area, like the study on fasting and fitness in postmenopausal women. It also follows research on how fasting affects menopause symptoms. This new study focused on cholesterol and blood vessel health, not weight or symptoms.

Who Was in the Study

Who they were: All 142 women were past menopause, between 50 and 60 years old. The abstract does not give their weight or health conditions beyond this. Not stated in the abstract.

What the fasting actually looked like: Women ate all their food within 8 hours each day, for 8 weeks. The Tai Chi group also did Yang-style 24-form Tai Chi, in 60-minute sessions, three times a week.

What Happened

The group that combined fasting with Tai Chi had the biggest drop in "bad" cholesterol and the best improvement in blood vessel flexibility.

• Total cholesterol and "bad" cholesterol (LDL) both dropped more in the fasting-plus-Tai-Chi group.
• The difference between fasting-plus-Tai-Chi and fasting-alone was unlikely to be due to chance.
• The difference between fasting-plus-Tai-Chi and the comparison group was also unlikely to be due to chance.
• Blood vessel flexibility improved in both the fasting-plus-Tai-Chi group and the fasting-alone group, compared to how they started.
• Only the fasting-plus-Tai-Chi group ended up clearly better than the comparison group on this blood vessel test.

What Did Not Change

• Blood sugar: The study measured it, but the abstract does not give the actual result. Not stated in the abstract.
• Nitric oxide and a blood vessel marker called endothelin-1: These were measured too, but no result is given in the abstract. Not stated in the abstract.
• Muscle mass: This was not measured in this study. Not stated in the abstract.

What the Researchers Said

The researchers concluded that combining the eating window with Tai Chi worked better than the eating window alone. They said mixing meal timing with structured movement may help heart and blood vessel health after menopause.

What This Means for You

• If you are past menopause: This study suggests pairing time-limited eating with gentle exercise may help your cholesterol more than fasting alone.
• Tai Chi is low-impact: You do not need intense workouts to see a possible benefit — this was slow, guided movement, three times a week.
• For women specifically: This study was done only in postmenopausal women, so it speaks directly to this group, unlike many fasting studies done mostly in men.
• Cholesterol is not the whole picture: Blood sugar and other blood vessel markers were tracked but not reported here, so this is not the full story.
• Check other menopause fasting research: See what a separate study found on fasting and menopause symptoms and on fasting's effect on women's hormones.
• Talk to your doctor first: Especially if you already take cholesterol medication or have heart disease.

What This Study Could Not Tell Us

• It ran for only 8 weeks, so it cannot say what happens over a year or longer.
• All 142 women were postmenopausal and aged 50 to 60 — results may not apply to younger women.
• The abstract does not report body weight, weight loss, or waist size for any group. Not stated in the abstract.
• The abstract does not say who paid for the study. Not stated in the abstract.
• Blood sugar, nitric oxide, and endothelin-1 results were not given, even though they were measured.

Common Questions

Does time-restricted eating help cholesterol after menopause?

This study found it can, especially when paired with Tai Chi. The combined group had the biggest drop in "bad" cholesterol out of all 142 women.

How long did the fasting window last in this study?

Women ate all their food within an 8-hour window each day. This continued for 8 weeks total.

What kind of exercise did they add to fasting?

Tai Chi — specifically Yang-style 24-form Tai Chi. They practiced it in 60-minute sessions, three times a week.

Did fasting alone still help blood vessel health?

Yes. Women who only followed the eating window also saw their blood vessel flexibility improve compared to how they started.

How many women were in this study?

142 postmenopausal women took part, split into three groups of around 47 to 48 each.
