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 (2,564 cal) minus a 22% deficit. This creates a 564 calorie daily deficit, translating to approximately 1.1 lbs of fat loss per week.
Protein Target
Set at 1.0g 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 32% 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 32% 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.
Running an aggressive cut for too long
A 22% deficit should not exceed 6-8 weeks. Longer aggressive phases cause metabolic adaptation, muscle loss, and hormonal disruption. Plan your timeline accordingly or switch to a moderate 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.
Weighing daily and reacting to fluctuations
Body weight can fluctuate 2-5 lbs daily from water, sodium, and food volume. A 170 lb person might weigh 4 lbs different on consecutive mornings with identical fat mass. Track weekly averages, not daily numbers.
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.
Plan for a diet break midway
Losing 25 lbs will take 20 weeks or more. Plan a 7-10 day diet break at maintenance around the halfway point. This prevents metabolic adaptation and makes the second half more effective.
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 1.5-2 lbs 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.

Frequently Asked Questions
How many calories should a 170 lb woman eat to lose weight?
A 170 lb woman with moderate activity typically needs 2040-2380 calories for cutting. This creates a 15-20% deficit from maintenance, allowing for 1.1-1.7 lbs of fat loss per week while preserving muscle.
How much protein does a 170 lb female need while cutting?
At 170 lbs, aim for 140-172g of protein daily (based on target weight of ~156 lbs). Higher protein during a cut helps preserve muscle mass and increases satiety.
What deficit should I use at 32% body fat?
At 32% body fat, you can safely use a 20-25% deficit. Your body has sufficient fat reserves to support 1.5-2 lbs of fat loss per week without significant muscle loss.
How long to cut from 32% to 20-24% body fat?
The timeline depends on your starting weight, but generally expect 24 weeks or more. Leaner individuals should plan for longer cuts with slower rates of loss.
