How Diet Can Curb Menopause Weight Gain, According to New Research

A major study has uncovered how diet can influence weight gain during menopause. Researchers from the NUS-Harvard Women's Health Initiative (NUSHINE) tracked nearly 40,000 women over several years. Their findings suggest that specific eating patterns may help reduce obesity risks linked to hormonal changes in later life. The study drew data from the long-running Nurses' Health Study II, focusing on women going through menopause. Hormonal shifts during this stage often lead to weight gain and a higher likelihood of obesity. Researchers analysed how different diets affected these changes.

Two dietary approaches stood out for their benefits. The Planetary Health Diet Index, which prioritises plant-based foods, cut obesity risk by 54%. Another effective pattern, the reverse Empirical Dietary Index for Hyperinsulinemia (rEDIH), slowed annual weight gain by 0.28 kg. This low-insulinemic diet helps regulate blood sugar and metabolism. In contrast, the study found that ultra-processed foods accelerated weight gain. These products were strongly linked to a higher risk of obesity. Most participants were Caucasian, but the team plans to expand research to include more diverse groups. Future work will also involve clinical trials to confirm these results. The findings highlight how plant-forward, low-insulinemic diets could support metabolic health during menopause. Such eating habits may offer a practical way to manage weight and reduce long-term health risks.

The research provides clear evidence that diet plays a key role in weight regulation during menopause. Plant-based, low-insulinemic eating patterns appear to lower obesity risk and slow weight gain. Further studies will explore these effects across broader populations and in controlled trials.
