Inflammation plays a major role in PCOS, weight gain, fatigue, insulin resistance, and hormonal imbalance—especially for women. Following an anti inflammatory diet for women over 40 can be a powerful way to address these issues. The anti-inflammatory diet for weight loss and PCOS is increasingly recommended by doctors, dietitians, and reputable health authorities because it targets the root causes of these challenges.
In 2024–2025, organizations such as National Institute of Health , Harvard Institute, Cleveland Clinic and Mayo Clinic, all emphasize the importance of reducing inflammation to improve metabolic and reproductive health. Their research aligns with what women experience in real life—when inflammation lowers, symptoms improve.
This guide breaks down everything you need to know in a simple, evidence-backed, women-focused way.
Understanding PCOS, Weight Gain, and Chronic Inflammation
What Is PCOS and Why Does It Cause Inflammation?
PCOS (Polycystic Ovary Syndrome) affects millions of women in the U.S., Canada, the UK, and Australia. What many women don’t know is that PCOS is strongly linked to chronic, low-grade inflammation.
This inflammation contributes to:
- Hormonal imbalances
- Weight gain, especially around the belly
- Irregular periods
- Increased insulin resistance
- High androgen levels
According to Cleveland Clinic’s 2024 PCOS update, inflammation is now considered one of the core drivers behind PCOS progression.
Why Women With PCOS Struggle With Weight Loss After 40
After age 40, most women experience:
- Slower metabolism
- Lower estrogen levels
- Higher cortisol during stress
- Increased insulin resistance
For women with PCOS, these factors multiply, making weight loss feel nearly impossible.
The Link Between Insulin Resistance, Hormones & Inflammation
Most women with PCOS have insulin resistance, which means the body struggles to use glucose effectively. This leads to:
- More inflammation
- Irregular hormone cycles
- More stored fat
- More cravings
The anti-inflammatory diet helps break this cycle naturally.
Benefits of an Anti-inflammatory Diet for Weight Loss and PCOS
- Reduces Inflammation for Hormonal Balance
Research from Harvard Health in 2024 shows that anti-inflammatory diets help regulate hormones, especially in women with metabolic conditions like PCOS.
- Supports Blood Sugar Control
Low-glycemic foods help reduce insulin spikes—the root cause of weight gain in PCOS.
- Improves Gut Health
A healthy gut reduces inflammation and improves mood, energy, and digestion.
