Fasting Plus Walking Boosted Muscle Strength in Postmenopausal Women: What the Research Shows

Fasting Plus Walking Boosted Muscle Strength in Postmenopausal Women: What the Research Shows

Researchers tested Nordic walking with time-restricted eating (only eating during set hours) and high protein, in 100 postmenopausal women. The trial lasted 12 weeks and 96 women finished it. Grip strength is a sign of muscle health. It improved most in the group doing all three together — more than walking with fasting alone.

The Short Version

• What they tested: Nordic walking plus time-restricted eating (only eating during set hours), with or without extra protein, versus no change.
• Who did it: Yang Y and colleagues at Chengdu Sports University in China, published in Nutrients in 2026.
• How many people: 100 postmenopausal women joined; 96 finished the study.
• How long: 12 weeks.
• What happened: Grip strength rose most in the group combining walking, fasting windows, and extra protein.

What They Wanted to Find Out

After menopause, many women lose muscle strength faster than before. Most past studies looked at exercise alone. This team wanted to know if adding fasting windows and extra protein to walking works better than walking and fasting by themselves. You can read more about fasting and fitness after menopause and how fasting affects muscle in general. This study asked a simple question: does stacking habits beat doing just one?

Who Was in the Study

Who they were: All 100 women were past menopause. The abstract did not give their exact ages or weight category.

What the fasting actually looked like: Time-restricted eating means eating only within a set number of hours each day. The exact hours used were not stated in the abstract. Women in two of the three groups combined this eating window with regular Nordic walking sessions.

What Happened

The group that combined walking, fasting windows, and extra protein gained the most grip strength of the three groups.

• Grip strength, a simple test of overall muscle health, rose in both groups that fasted and walked.
• Walking speed and a chair-stand test (a measure of leg power) followed the same pattern.
• The group adding protein saw the best results across strength and movement tests.
• Women stuck to the walking, fasting, and protein plans well throughout the 12 weeks.
• The comparison group, who changed nothing, showed almost no change on any test.

What Did Not Change

• Lean mass — the muscle part of body weight — held up better in the group that added protein.
• The fasting-only walking group showed a less favorable pattern for lean mass than the protein group.
• No group in this study was reported to lose meaningful muscle overall.
• The comparison group's measurements stayed roughly flat, since they made no changes.

What the Researchers Said

The team said combining walking, fasting windows, and protein together gave the best overall pattern of change. They were careful to say this shows differences between whole packages of habits — not proof that any single piece works alone.

What This Means for You

• Walking alone may not be enough: pairing it with an eating window and more protein showed bigger gains here.
• This was tested in women only: every participant was a postmenopausal woman, which is rare and useful data.
• Muscle worries may ease: no group showed meaningful muscle loss, which matters for women fearing fasting weakens them.
• Small daily habits add up: the biggest changes came from stacking three habits, not from one alone.
• See related fasting research: check fasting and menopause symptoms and women's hormones and fasting windows.
• Talk to your doctor first: especially before starting a new eating pattern alongside new exercise.

What This Study Could Not Tell Us

• It ran for only 12 weeks, so it cannot say what happens over a year or more.
• All 100 women were postmenopausal, so results may not apply to younger women.
• Four women dropped out before the end, leaving 96 in the final results.
• The study cannot separate the effect of walking, fasting, or protein alone from each other.
• Funding for the study was not stated in the abstract.

Common Questions

Does time-restricted eating help muscle strength after menopause?

This study found grip strength improved more in women who combined an eating window with walking. It improved most when protein was added too. It did not test fasting on its own.

How many women were in this fasting and walking study?

100 postmenopausal women joined the trial. 96 completed all 12 weeks of testing.

Did the fasting group lose muscle?

No group in this study showed meaningful muscle loss. The group without extra protein showed a less favorable pattern than the protein group, but not clear loss.

How long did the study last?

The trial ran for 12 weeks. The researchers said longer studies are needed to know if results last.

Can I try walking, fasting, and extra protein together?

Talk to your doctor before changing your eating window or starting new exercise, especially after menopause. This study suggests combining habits may help, but it was only 12 weeks long.
