Mediterranean. Blue Zone. Whole foods. Low-carb. High-protein. Time-restricted eating. Sometimes eating for long-term health feels less like science and more like chasing moving goalposts. And just when you think you’ve landed on the “right” pattern, another one takes its place. 

Choosing what to eat for good health shouldn’t be about chasing whatever’s loudest right now. It’s about protecting what matters: your heart, your metabolism, your muscle, and your independence. 

This week, we dive into six priorities that protect your heart, metabolism, and muscle for decades. But before we get practical, let’s answer a foundational question: Do women actually need a different approach when it comes to eating for longevity?

The Livelong Women’s Health Summit is fast approaching. Lock in your seat now — and if you’re considering VIP, don’t wait. Availability is extremely limited.

A recent article asked whether men and women should follow different diets for longevity. Unfortunately, “we have very few studies that were intentionally designed and adequately powered to test whether men and women respond differently to the same dietary pattern,” says Debbie Petitpain, MBA, RDN, spokesperson for the Academy of Nutrition and Dietetics. “Overall, the strongest evidence supports that healthy dietary patterns improve cardiometabolic health in both women and men, and that the direction of benefit is usually the same.” When differences appear, they’re usually about magnitude — not that one sex benefits and the other doesn’t, Petitpain adds.

💡 In other words, men and women don’t appear to need entirely different diets, but, the stakes and timing may differ.

Where we do have sex-specific data, it’s notable. For example, a 2023 systematic review in Heart found that higher adherence to a Mediterranean diet was associated with roughly 24% lower cardiovascular disease risk in women. And data from SWAN and the American Heart Association indicate that the menopause transition drives shifts in body composition, lipids, insulin resistance, and vascular health beyond those driven by aging alone. Visceral fat increases, LDL cholesterol rises, and cardiovascular risk accelerates in the decade after menopause. 

Menopause shifts the metabolic terrain, unfortunately, this is where women most often go off track.

In practice, Johnston sees a few patterns that show up repeatedly. Here are the main habits where things start to unravel for women focused on long-term, good health:

So, what does getting it right actually look like?

For women who want their heart and metabolism to stay healthy into their 70s and 80s, the goal isn’t restriction. It’s resilience.

That means a Mediterranean-style, protein-adequate pattern, minimal ultra-processed foods, muscle-preserving exercise, and an eating schedule that supports good sleep and activity, says Johnston. “The goal is a pattern a woman can live with for decades, not a short-term diet.” Here are her six top tips:

Build meals around adequate protein to preserve muscle, support satiety, and improve metabolic control. Expert groups like PROT-AGE and ESPEN suggest older adults may benefit from about 1.0–1.2 grams per kilogram of body weight per day — often higher than the standard RDA — especially when paired with resistance training.

Use a Mediterranean-style pattern as your default structure: olive oil, vegetables, legumes, nuts and seeds, fish, lean meats, and minimally processed carbohydrates. It has the strongest cardiovascular prevention evidence.

Reduce refined carbohydrates and added sugars. Pair carbs with protein, fiber, and fat to blunt glucose spikes. After menopause, insulin resistance often becomes less forgiving.

Nutrition and resistance training are inseparable and “longevity eating” without muscle-preserving exercise is incomplete. The menopause transition is a poor time to chase weight loss at the expense of lean mass. Muscle is metabolic insurance.

A consistent 10–12-hour daytime eating window can support circadian alignment for some women. Think breakfast within a couple of hours of waking and your last meal several hours before bed. Avoid prolonged fasting unless there’s a clear medical reason and good tolerance.

If prevention is the goal, monitor more than the scale: blood pressure, fasting glucose and HbA1c, fasting insulin, lipids (ideally ApoB and lipoprotein(a)), waist circumference, body composition, strength, and fitness capacity. In some cases, imaging for subclinical plaque can provide early insight.

If you want to stay strong into your 70s and 80s, the priorities aren’t mysterious. It’s about building a pattern you can sustain when life is busy, stressful, and imperfect — not just when motivation is high.

As Petitpain puts it, “The evidence strongly supports that our food choices dramatically influence longevity and cardiometabolic health for everyone, but there's not a one-size-fits-all approach to healthy eating.” Personalization becomes important when we consider sex alongside life stage, metabolic risk, culture, and lifestyle.

Join Dr. Mary Claire Haver, Dr. Vonda Wright, and other leading physicians at the Livelong Women’s Health Summit as they break down what actually shifts after 40 — from muscle loss to cardiometabolic risk — and what to do about it  at the Livelong Women’s Health Summit.

Across two days, more than 75 experts will share practical strategies for protecting strength, heart health, and independence for decades to come.
