Key Considerations

Protein: 0.8-1.2g per pound bodyweight, higher when cutting
Carbs: primary fuel for intense training, adjust based on activity
Fat: minimum 0.3g per pound for hormone health
Macros shift between bulking (more carbs) and cutting (higher protein, moderate carbs)
Meal timing around training can optimize performance and recovery

Specific Adjustments

Bulking Phase

Higher carbs (2-3g/lb), moderate protein (0.8-1g/lb), lower fat (0.3-0.5g/lb).

Cutting Phase

Higher protein (1-1.2g/lb), moderate carbs (1-2g/lb), moderate fat (0.3-0.4g/lb).

Tips for Best Results

1Weigh and track all food for accuracy

2Adjust macros every 2-4 weeks based on progress

3Prioritize carbs around training for performance

4Keep fat intake consistent for hormone health

Frequently Asked Questions

What macro split is best for building muscle?

A common effective split is 30% protein, 50% carbs, 20% fat. However, total protein (0.8-1g/lb) and total calories matter more than exact percentages. Adjust based on your response.

How do I adjust macros for cutting?

Increase protein to preserve muscle (1-1.2g/lb), reduce carbs or fat (or both) to create the deficit. Keep protein and training intensity high while reducing overall calories.

Should I cycle carbs?

Carb cycling (higher carbs on training days, lower on rest days) can work but is not necessary. It adds complexity without proven superior results. Consistent macros are easier to sustain.
