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 15% deficit. This creates a 384 calorie daily deficit, translating to approximately 0.8 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.
Getting impatient with slower progress
A conservative 15% 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.
Weighing daily and reacting to fluctuations
Body weight can fluctuate 2-5 lbs daily from water, sodium, and food volume. A 160 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.
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.
