Can I adjust the size of individual meals after getting the split?

Yes, absolutely! The planner provides an even macro split across all meals as a starting point. You can manually adjust individual meal sizes based on your personal preferences, training schedule, or hunger levels. For example, you might make your pre- and post-workout meals larger with more carbohydrates, and scale down other meals slightly to balance the total daily macros.

Is this planner suitable for specific diets like Keto or Vegan?

Yes, the planner is highly adaptable. You simply need to input the appropriate macronutrient percentages for your specific diet. For a ketogenic diet, you would set very low carbs (e.g., 5-10%), moderate protein, and high fat. For a vegan diet, you would input your desired macro percentages, then select food sources that align with vegan principles to meet those targets.

How often should I re-evaluate my meal macro split plan?

You should re-evaluate your plan whenever your fitness goals change, your activity levels significantly increase or decrease, or if you hit a plateau. A good general guideline is to reassess every 4-8 weeks. Pay attention to how your body feels, your energy levels, and if you are making progress towards your objectives to determine when an adjustment is needed.

The short answers readers usually want after the first pass.

The calculator will typically prompt you if your percentages don't sum to 100%. For accurate results, always ensure that your protein, carbohydrate, and fat percentages combined equal exactly 100%. If they are slightly off, the planner might automatically adjust one macro proportionally, but it's best to input accurate figures from the start to maintain your intended balance.
