Women in peri/menopause are often told to “just eat healthy.” Yet science shows that the same food can affect different women in very different ways — especially when hormonal shifts begin to affect metabolism and the gut microbiome.
In the book The Personalized Diet, researchers Eran Segal and Eran Elinav discuss groundbreaking research showing that people can have completely different blood sugar responses to the exact same foods.
In their large study of 800 participants(they reached 5000 participants by the end of the study), researchers discovered that gut microbiome composition, lifestyle, sleep, stress, and metabolic health strongly influenced how the body responded to food.
This is especially important for women in perimenopause and menopause because declining estrogen levels can:
• reduce insulin sensitivity
• increase inflammation
• alter gut microbiome diversity
• promote visceral fat storage
• worsen cravings, fatigue, bloating, and glucose instability
What works for one woman may not work for another.
A food considered “healthy” for one person may create blood sugar spikes, inflammation, or digestive symptoms in someone else.
The future of metabolic health is becoming more personalized — focusing on gut health, blood sugar responses, sleep, stress, movement, and hormonal changes(age and s*x, I would add).
Your body is not “failing” in menopause.
It may simply need a more individualized approach.
