The Thrive Method Weekly: Eating Less Is Wrecking Your Metabolism
For women over 40, eating too little is one of the most common reasons the scale won't move.
Wednesday, March 4, 2026
Hey there -
March feels like a fresh start in a way January never quite does for me. The pressure of “new year, new you” is gone, and what’s left is just the quiet intention to actually do the things that matter. That’s the energy I’m bringing into this month — and it’s the energy behind everything I’m building here on Substack right now.
This week I want to challenge something that most of us have been told our entire lives — because for women over 40, it’s not just wrong, it’s actively working against you. Before we get to what’s cooking, I want to share something that I think will genuinely change how you approach food.
The Method Moment: Eating Less Is Wrecking Your Metabolism
I know that’s a bold statement. But after losing 90 pounds and spending years helping women over 40 do the same, I can tell you with confidence: chronic undereating is one of the most common reasons women in this season of life can’t lose weight — or keep losing muscle while the scale barely moves.
Here’s what’s actually happening:
Your body is smarter than your calorie deficit. When you consistently eat too little, your body interprets that as a threat. It doesn’t know you’re trying to fit into last summer’s jeans — it thinks food is scarce. So it does what it’s designed to do: it slows your metabolism, holds onto fat stores for emergency fuel, and starts breaking down muscle tissue instead. This is called adaptive thermogenesis, and it’s the reason so many women hit a wall and stay there no matter how little they eat.
After 40, muscle loss accelerates this problem dramatically. Muscle is metabolically expensive — it burns calories just existing. When you undereat, you lose muscle. When you lose muscle, your metabolism slows further. When your metabolism slows, you eat even less to compensate. It becomes a cycle that’s genuinely hard to break, and it’s why women who’ve been chronic dieters for years often have metabolisms that are significantly slower than they should be for their age.
The hunger signals get confused. Long-term undereating disrupts ghrelin and leptin — the hormones that regulate hunger and fullness. This is why chronic dieters often report not feeling hungry even when they haven’t eaten enough, or feeling hungry constantly no matter what they eat. The signaling system is dysregulated, not broken — but it needs consistent, adequate nutrition to recalibrate.
What “eating enough” actually looks like after 40. This isn’t permission to eat everything in sight. It’s about eating enough of the *right things* — specifically protein and fiber at every meal — to preserve muscle, keep metabolism running efficiently, and give your hormones what they need to function. For most women over 40, that means eating *more* than they think, structured around protein anchors of 25–40g per meal.
The Thrive Method is built around this principle. Not restriction. Structured nourishment.

Smashed Crab Tacos with Cabbage Slaw & Cilantro Lime Crema
High protein · High fiber · The slaw is 🔥
I did to crab cakes what smash burgers did to burgers — pressed the crab mixture directly onto a high-fiber tortilla and cooked them together into one crispy, golden unit. The result is everything you want in a taco: rich, crunchy, fresh, and creamy. Crab is naturally high in zinc, selenium, and B12 — three nutrients that don’t get talked about nearly enough for women over 40 — and between the tortilla, cabbage slaw, and avocado you’re getting a serious fiber hit too. This one goes into regular rotation.
Low Carb Cabbage Lasagna
High protein · High fiber · Comfort food that works for you
My cabbage bread has over 30 million views for a reason — cabbage is one of the most underrated ingredients in a high-fiber kitchen. Here I’m using it as lasagna noodles, and the trick that makes it work is roasting the leaves first rather than boiling them. That step drives out excess moisture and caramelizes the edges slightly, giving you depth of flavor you simply can’t get any other way. Ground bison, Rao’s sauce, fresh ricotta, and fresh mozzarella — layers of real comfort food that’s quietly doing everything right for your protein, fiber, and gut health. This is the kind of meal that makes you forget you ever needed pasta.
Spicy Mussel Pasta (paid subscriber only)
Five ingredients, under 20 minutes, and one of the most nutrient-dense dinners I’ve made in a long time. One tin of mussels gives you 18g of complete protein, triple the B12 of salmon, and more selenium than almost any other protein source — selenium being one of the key nutrients that protects existing collagen from oxidative breakdown. Paid subscribers get the full recipe.
Thrive 90: A 90-Day Framework to Feel Lighter, Stronger & More Energized
The 12-week structured program built around everything I talk about here: high protein, high fiber, gut health, in a complete roadmap. If you're ready to stop piecing it together and want the full system, this is it. Hundreds of women have gone through it. It works because it's structured, not because it's extreme.
High Protein, High Fiber & High Flavor Cookbook Bundle
My most popular cookbook bundle featuring over 130 easy healthy recipes for breakfast, lunch and dinner. Each recipe has a QR code that takes you to a video demo of how to make it. If you’re feeding a family or just want to make this way of eating easy, this is your starting point.
OXO Adjustable Mandoline Slicer
I get asked about this constantly — it’s in basically every cabbage recipe I make, including the lasagna above. The OXO adjustable mandoline is the one I’ve used for years and the reason my veggies come out just like I like them and even every single time. It’s also one of those kitchen tools that quietly makes healthy eating faster — when prep is effortless, you actually do it. I’ve also had mine for years and years - and even with daily use, it’s held up beautifully.
Sungboon Editor Collagen Melting Patches
These are my current obsession. Collagen support from the inside through food and supplementation is always the foundation — but targeted topical patches are a genuinely useful complement, especially for the areas that need a little extra attention. These melt into the skin rather than sitting on top of it, which means they’re actually absorbing rather than just hydrating the surface. I use them a few times a week and the difference in firmness and texture is real.
NYX UNglue Melting Balm Cleanser
A clean, effective double cleanse is one of the most underrated skincare habits — and this balm makes it effortless. It melts away makeup, sunscreen, and the day without stripping anything, which matters more after 40 when your skin barrier needs more support, not less. And it’s under $10.
That’s it for this week. March is a good month to start something — and you already have. As always — consistent, not perfect. Structure, not restriction.
