Cutting Protocol for Women Over 40
Age-adjusted cutting macros for women over 40. Learn the specific adjustments needed for effective fat loss.
Your 40s bring metabolic changes, but they're often exaggerated. The bigger culprit is typically reduced activity and accumulated stress. A well-designed cut at this age focuses on maintaining training intensity, optimizing sleep, and being patient with the process. Results come just as predictably—sometimes more so, given your experience.

The Science Behind These Numbers
These macros are calculated using the Cunningham equation (when body fat is known) or Mifflin-St Jeor equation as a fallback. Here's what each number means:
Calorie Target
Your TDEE (2,558 cal) minus a 12% deficit. This creates a 307 calorie daily deficit, translating to approximately 0.6 lbs of fat loss per week.
Protein Target
Set at 0.8g per pound of target body weight. Research shows 0.8-1.2g/lb preserves muscle during a deficit. Higher protein also increases satiety and has a high thermic effect.
Fat Target
Minimum 0.3g per pound bodyweight to maintain hormone production. Fat is essential for testosterone, estrogen, and overall hormonal health during a caloric deficit.
Carb Target
Remaining calories after protein and fat are set. Carbs fuel your training and preserve muscle glycogen. Prioritize them around workouts for best performance.
Common Mistakes to Avoid
Expecting linear progress the entire cut
At 28% body fat, the first 4-6 weeks will show rapid changes—don't expect that pace to continue. As you get leaner, fat loss slows naturally. Mentally prepare for this transition around weeks 8-10.
Adding excessive cardio from day one
You don't need an hour of cardio daily at 28% body fat. Diet alone creates your deficit. Save cardio as a tool for when progress stalls—if you start maxed out, you have nowhere to go.
Ignoring recovery and sleep quality
In your 40s, sleep becomes even more critical for results. Poor sleep increases cortisol, impairs recovery, and makes fat loss significantly harder. Eight hours isn't a luxury—it's a requirement.
Getting impatient with slower progress
A conservative 12% deficit means slower scale movement—often only 0.5-0.75 lbs per week. This is by design. If you panic and slash calories, you negate the muscle-preserving benefits of the conservative approach.
Inconsistent protein intake
At your target of 145 lbs, you need 138-160g of protein daily—not just on training days. Muscle protein synthesis doesn't take days off, and neither should your protein intake.
Keys to Success
Trust the process through the 'whoosh'
At higher body fat percentages, fat loss often happens in spurts—you'll retain water for days, then suddenly drop 2-3 lbs overnight. This "whoosh effect" is normal. Don't adjust calories during water retention phases.
Master your sleep environment
In your 40s, sleep quality often degrades. Blackout curtains, cool temperatures (65-68°F), and no screens 1 hour before bed can improve sleep quality dramatically—which directly impacts fat loss and recovery.
Build your protein-first habit
At every meal, ask: "Where's my 36g of protein?" This simple habit ensures you hit your 145g daily target across 4 meals. Protein first, then fill in carbs and fats.
Weekly weigh-ins beat daily stress
Pick one day (ideally after a rest day) and weigh yourself first thing in the morning. This weekly average approach eliminates the anxiety of daily fluctuations and shows true fat loss trends.
Your Week-by-Week Focus
Weeks 1-4: Focus on establishing consistent eating patterns. Don't stress about perfection—aim for 80% adherence. Your body will respond quickly at this stage, shedding water and fat simultaneously. Target 0.5-1 lb per week on average.
Weeks 5-8: Progress may appear to slow as initial water weight is gone. This is normal. Stay the course, and consider adding one 30-minute cardio session if you haven't already. Don't adjust calories yet.
Weeks 9+: If progress stalls for 2+ weeks, reduce calories by 150-200 or add another cardio session. Implement a refeed day if hunger becomes unmanageable.
What You Get with CutSpec
Frequently Asked Questions
Is cutting harder over 40?
Some metabolic slowdown occurs over 40, but the bigger factor is often reduced activity. Focus on maintaining muscle through resistance training and adequate protein.
How much protein do I need over 40?
Aim for 0.9-1.1g per pound of target body weight. Slightly higher protein helps offset age-related muscle loss.
How aggressive should my cut be over 40?
Moderate deficits (15-18%) work well over 40. Avoid extremes and prioritize recovery.
What's different about cutting over 40?
Focus on recovery, joint health, and maintaining strength. You may need slightly more rest days and attention to sleep quality.
