If you’re hitting a wall every afternoon no matter how much coffee you drink, I want you to stop blaming your sleep and look at your blood sugar.

Here’s what’s happening under the surface: when you eat a big load of refined carbs on an empty stomach, your blood sugar spikes fast. What shoots up that quickly comes crashing down just as hard, and your brain runs on steady glucose, so when it drops, you feel the fog, the fatigue, and the cravings. That’s the 3pm slump. It’s a rollercoaster, and the whole goal is keeping the ride smooth.

The good news is that a few small shifts change everything:

Anchor every meal with protein. It slows digestion, steadies your energy for hours, and keeps you full so you’re not reaching for the carbs an hour later.

Never eat carbs alone. An apple by itself spikes you. An apple with a handful of walnuts gives you a slower, gentler rise because the fat, protein, and fiber slow it all down. Same idea with rice plus chicken, or eggs on your toast.

Have your coffee after protein, not before. Caffeine on an empty stomach is a blood sugar spike waiting to happen, so eat first.

And build your day around the foods that keep energy steady: eggs, salmon, Greek yogurt, spinach, bananas, and slow-digesting carbs like quinoa.

Here’s the thing though, your body is unique. The way your blood sugar responds to a meal isn’t the same as mine. The only way to stop guessing and actually see what’s steadying your energy versus crashing it is to watch it in real time, and that’s exactly what we do inside CGM LEAN.

If you’ve been doing everything “right” and the scale won’t budge, read this before you blame yourself one more time.

In your 30s, your body had backup. Estrogen was quietly helping you regulate blood sugar and respond to insulin the way it’s supposed to. Fat loss still took effort, but the effort actually paid off.

Then perimenopause shows up and the rules change overnight. Estrogen and progesterone start to decline. Insulin sensitivity drops. Cortisol runs higher. And your body starts storing fat almost effortlessly, especially around your midsection, in a way it never did before.

Same effort. Completely different results.
And here’s the part that makes me the most frustrated for you: nobody explained any of this. Your doctor said your labs were “normal.” The diet industry kept handing you the same advice that quietly stopped working years ago. So you did what any determined woman would do. You tried harder. You ate less. You moved more. And you still felt stuck.

It was never a willpower problem. It’s a physiology problem, and physiology responds to the right strategy, not more punishment.

The good news? There are specific things that actually move the needle after 40, and they’re very different from what you were told in your 30s.

And this is exactly what I cover in my LEAN program. We start this week. Click here for more details: https://amandanighbert.com/lean-program/

I’ve been a Registered Dietitian for 20+ years and worked with thousands of women in their 40s, 50s, and 60s. I can tell you with complete confidence: most of you aren’t failing at weight loss because you lack willpower.

You’re failing because you’re doing what USED to work in your 20s and 30s. Your body isn’t 27 anymore.

Here are the 5 things I need you to stop doing today:
❌1. Stop under-eating. Surviving on 1,200 calories and a prayer? You’re destroying your metabolism. Chronic under-eating tanks your thyroid, spikes cortisol, and eats your muscle for fuel. You need to eat MORE of the right things.
❌2. Stop doing only cardio. Hours on the treadmill isn’t the answer. After 40, every year you don’t strength train, you lose muscle. Less muscle = slower metabolism. Lift. Heavy. Twice a week minimum.
❌3. Stop snacking all day. The “6 small meals” advice was bad in 2005 and it’s still bad now. Constant grazing keeps insulin elevated all day, which keeps you in fat-storage mode. 3 to 4 solid meals. That’s it.
❌4. Stop weighing yourself every morning. The scale is lying to you. Hormones, water, sodium, sleep, and cycle phase move that number 2 to 4 pounds either direction on any given day. Measure inches. Take photos. Notice how your clothes fit.
❌5. Stop skipping protein at breakfast. Coffee, a granola bar, or a yogurt parfait with 8 grams of protein sets up your blood sugar, hunger hormones, and cravings to wreck your whole day. 30 grams of protein before 10am. Non-negotiable.

If you read that and thought “I’m doing at least 3 of those,” you’re not alone. You’ve just been handed outdated advice for a decade.

This is exactly why I built LEAN.
LEAN is 4 weeks of real food, real structure, and a framework built for how your body works after 40.

Right now during LEAN DAYS, you can join for just $99, the lowest it’ll ever be!
