Nutrition Guidelines

Calorie Deficit

Calculate your needs:

Maintenance: Bodyweight × 14-16
Fat loss: Maintenance - 500 calories

Example (180 lb person):

Maintenance: ~2,700 calories
Fat loss: ~2,200 calories

Macronutrients

Protein (Priority #1):

1g per pound bodyweight
Protects muscle during deficit
Most important macro for fat loss

Carbohydrates:

0.75-1g per pound bodyweight
Focus around training
Adjust based on energy

Fats:

Remaining calories
Minimum 0.3g per pound
Essential for hormones

Sample Macros (180 lb person, 2,200 cal)

| Macro | Grams | Calories | |-------|-------|----------| | Protein | 180g | 720 | | Carbs | 180g | 720 | | Fat | 85g | 765 | | Total | - | 2,205 |

Meal Timing

Pre-workout (1-2 hours before):

Protein + carbs
30-40g protein, 30-50g carbs

Post-workout (within 2 hours):

Protein + carbs
30-40g protein, 40-60g carbs

Other meals:

Spread protein evenly
Vegetables at every meal

Sample Day of Eating

Breakfast: 4 eggs + vegetables + 1 slice toast Lunch: 6 oz chicken + large salad + olive oil dressing Pre-workout: Greek yogurt + banana Post-workout: Protein shake + rice cakes Dinner: 8 oz salmon + vegetables + small potato

Supplements (Optional)

Evidence-Based

Protein Powder:

Convenient protein source
Helps hit daily target
Not magic, just food

Creatine:

Maintain strength during deficit
5g daily
Safe and effective

Caffeine:

Pre-workout energy
Slight metabolic boost
100-200mg before training

Skip These

Fat burners (mostly ineffective)
Detox teas (waste of money)
"Metabolism boosters" (don't work)

Recovery Strategies

Sleep

Critical during fat loss:

7-9 hours minimum
Sleep deprivation increases hunger
Recovery happens during sleep
Prioritize this above all else

Stress Management

High cortisol impairs fat loss:

Find stress outlets
Don't add excessive training stress
Rest days are important

Active Recovery

On rest days:

Light walking (5,000-10,000 steps)
Stretching or yoga
Don't sit all day

What to Expect

Week 1

Initial water weight drop (3-5 lbs)
Possible hunger adaptation
Learning the routine

Week 2

Hunger normalizing
Energy adapting
Weight loss steadying

Week 3-4

Visible changes starting
1-2 lbs per week fat loss
Strength maintained or slightly down

Week 5-6

Noticeable transformation
Clothes fitting differently
Definition appearing

Realistic Results

In 6 weeks:

6-12 lbs fat loss possible
Visible body composition change
Strength largely maintained
Significant waist reduction

Common Mistakes

Cutting Calories Too Aggressively

Problem: More than 750 calorie deficit Result: Muscle loss, metabolism crash Fix: Moderate 500 calorie deficit

Skipping Strength Training

Problem: All cardio, no weights Result: Muscle loss, "skinny fat" result Fix: Prioritize strength training

Not Eating Enough Protein

Problem: Under 0.7g per pound Result: Muscle loss Fix: 1g per pound minimum

Too Much Cardio

Problem: 2+ hours daily Result: Overtraining, muscle loss Fix: Strategic cardio as prescribed

Impatience

Problem: Expecting results in days Result: Giving up too soon Fix: Trust the process, 6 weeks minimum

Weekend Blowouts

Problem: Strict weekdays, binge weekends Result: No net deficit Fix: Consistent daily adherence

Tracking Progress

Weekly Check-Ins

Every week, same day:

Morning weight (before eating)
Progress photos
Waist measurement
Strength numbers

Interpreting the Scale

Scale fluctuates due to:

Water retention
Food volume
Sodium intake
Hormones

Look at weekly averages, not daily numbers.

When to Adjust

If no progress for 2+ weeks:

Reduce calories by 200
Add one LISS session
Check adherence first

After the Program

Option 1: Continue Cutting

If not at goal, continue with slight calorie reduction.

Option 2: Reverse Diet

Gradually increase calories back to maintenance:

Add 100-150 calories per week
Maintain training
Prevent rapid weight regain

Option 3: Maintenance Phase

Eat at maintenance for 4-8 weeks before next cut:

Gives body a break
Resets metabolism
Mentally refreshing

Summary

This 6-week fat loss program combines:

Strength training to preserve muscle
Strategic HIIT for calorie burn
LISS for additional deficit
Nutrition for sustainable fat loss

Keys to success:

500 calorie deficit consistently
1g protein per pound bodyweight
4 strength sessions per week
2-3 cardio sessions per week
7-9 hours sleep
Patience and adherence

Six weeks is enough time for a meaningful transformation. The work is straightforward—the challenge is consistency.

Commit fully. Execute daily. Transform your body.
