Healthy Habits for Busy Moms in Their 40s Who Are Eating Less, Doing More Cardio, and Still Gaining

I was eating 1,200 calories and riding my Peloton five days a week when my jeans stopped zipping. I lost 25 pounds by lifting heavier and fueling instead of cutting, and that’s exactly what I coach in Thrive Again.

You’re Not Failing. Those Plans Were Failing You.

Eat less, move more. It worked in your 20s. After 40, it can stall your metabolism instead.
Calorie calculators are built on averages. After 20 years as an actuary, I can tell you averages rarely describe the woman in front of you. Your plan should start from your week, not the formula.

How I Help

I help women in their 40s lose the weight that won’t budge and get their energy back, without more cardio or fewer calories.

My approach is metabolism-first. We find what’s actually stalling you, whether that’s under-fueling, stress and sleep, or lost muscle. Then we fix that first with strength training, real meals, and recovery.

Thrive Again is 12 weeks of 1:1 coaching with me, built around your real schedule.

  • Where I Started: 1,200 calories, five cardio rides a week, skipping breakfast, stuck.


    Where I Am Now: Lifting 25-pound dumbbells, eating protein at every meal, 25 pounds down, and jeans that fit better than they did before kids.

Transform Your Wellness with Simple, Lasting Habits

The Metabolism-First Approach


Most plans tell you to eat less and move more. After 40, I start with three different rules.

Fuel, Don’t Restrict

Eating enough, especially protein and fiber, is what gives your metabolism something to work with.

Lift, Don’t Just Log Miles

Short strength sessions rebuild the muscle that keeps your metabolism running. More cardio usually doesn’t.

Recover, Don’t Push Through

Sleep and stress affect your weight as much as your workouts do.
