Why Protein Matters for Women Over 40

Why Protein Matters for Women Over 40
Once you hit 40, hormonal shifts and age-related muscle loss (sarcopenia) can make it harder to stay fit and energized. Protein is the key macronutrient that supports lean muscle growth, protects bone density, and keeps your metabolism humming.
Here’s a closer look:
- Build & Preserve Lean Muscle: Protein is essential for muscle repair, which in turn supports a higher resting metabolic rate.
- Boost Metabolism: Thanks to the thermic effect of protein, your body burns more calories digesting and utilizing protein than it does with carbs or fats.
- Stay Satiated: High-protein meals help curb cravings and stabilize blood sugar — vital for maintaining energy throughout the day.
How Protein Fits into the Full Macronutrient Picture
A balanced macronutrient diet contains protein, carbohydrates, and healthy fats. At 40 years young and beyond, prioritizing protein is especially crucial for hormone balance, muscle preservation, and steady energy. That’s where the WB4 Method — the core philosophy behind WarriorBabe — comes in.

How Much Protein Do You Really Need?
A good rule of thumb is to eat 1 gram of protein per pound of target body weight. Yes, that sounds like a lot, but you’ll quickly feel and see the difference! We have a specific macro calculator we use in our WarriorBabe VIP Program, but there are some general guidelines you can follow to get pretty close.
- Spread your protein across 4-5 meals, using options like chicken, Greek yogurt, tofu, beans, or protein shakes.
- Avoid “batching” your protein and getting it all in 1 or 2 meals — a slow release into the body will help you maintain your results long-term and avoid energy peaks and troughs.
- Keep your macros (especially protein) consistent on both workout and non-workout days — give your body the fuel it needs to repair!

Pre and Post Workout Meals for Maximum Results
Properly fueling your body before and after a workout is crucial — especially if you’re aiming to build lean muscle and stay energized in your 40s and beyond. Here’s how to get the most out of every training session:
- Pre-Workout Meal
- Goal: Provide steady energy and prime your muscles for performance.
- When: 20–90 minutes before your workout, on the lower end for meals with more simple carbs and on the higher end for complex carbs and fuller meals.
- What to Include:
- Protein: Around 20g to kick-start muscle protein synthesis (e.g., Greek yogurt, lean turkey, a protein shake).
- Complex Carbs: Whole grains, oats, or fruit for sustained energy.
- Healthy Fats (Optional): A small amount of avocado or nuts if you’re prone to quick hunger, but aim to keep this under 8 grams total
- Protein: Around 20g to kick-start muscle protein synthesis (e.g., Greek yogurt, lean turkey, a protein shake).
- Goal: Provide steady energy and prime your muscles for performance.

- Post-Workout Meal
- Goal: Jumpstart recovery, replenish glycogen, and repair muscle tissue.
- When: Ideally within 30–60 minutes after your workout.
- What to Include:
- Protein: Around 20–30g to maximize muscle recovery (e.g., whey protein shake, chicken breast, egg whites).
- Carbs: Faster-digesting carbs like white rice, a banana, or sweet potato help restore energy levels.
- Hydration: Don’t forget water (or an electrolyte beverage) to replace fluids lost through sweat. Just watch out for high sugar content and artificial sweeteners! Coconut water (unsweetened) is an excellent natural source of electrolytes if you enjoy the flavor.
- Protein: Around 20–30g to maximize muscle recovery (e.g., whey protein shake, chicken breast, egg whites).
- Goal: Jumpstart recovery, replenish glycogen, and repair muscle tissue.

Meal Planning & Macros: Bringing It All Together
One of the biggest perks of WarriorBabe meal plans is personalized macro guidance, especially around protein. You’ll know exactly what to eat, in what portions, and when, so you never guess whether you’re getting enough protein or missing a critical nutrient. But here are a few rules of thumb to get you started:
- Meal Prep Tips: Use lean meats, eggs, or plant-based protein sources. Prep in bulk and build your meals around your protein sources to help you hit your targets.
- Snack Smart: Greek yogurt, protein bars, or cottage cheese can keep cravings in check.
Stay Consistent: Log your target macros in MyFitnessPal and aim to be within 5 grams of your ideal protein, carbs, and fats day-to-day.

Extra Benefits of Focusing on Protein as a 40+ Woman
In case you need extra incentive to add more protein to your diet, here are a few extra bonuses you gain from eating more, more consistently:
- Hormone Balance – Stable blood sugar from protein-based meals can positively influence cortisol, insulin, and estrogen levels — helping you feel more in control, more balanced, and more vibrant throughout the day.
- Bone Health – Protein helps maintain bone density, helping combat the risk of osteoporosis in conjunction with regular strength training.
Enhanced Energy – Adequate protein curbs energy crashes that often come from focusing heavily on carbs and fats, enabling you to be more present in your life.
Final Word: Protein Fuels Your Prime Years
Getting enough protein after 40 isn’t a luxury — it’s essential. You’ll see the impact in your waistline, your workouts, and your day-to-day energy. Prioritize protein, stay consistent with strength training, and watch your body and confidence transform. Pair that with the comprehensive support of our proven WB4 Method, and you’ll have everything you need to conquer your goals.
