Your IIFYM Macro Calculator Results

The numbers in the IIFYM Macro Calculator are your specific daily macros. In order to accomplish your physique changing goals, you should eat the exact amount of fat, carbs, protein and fiber listed in the IIFYM Macro Calculator every day, regardless if you exercise or not. Please remember that these numbers are a guide, and are based on formulas. The IIFYM Macro calculator cannot account for metabolism health or damage, so some modifications may need to be made. After following these IIFYM Macro Calculator macros consistently for 4 weeks you should notice a change in weight or physical appearance. If you do not notice any changes, your total calories may be too high, or in some rare cases too low, and you will need to be adjusted accordingly. If you do need to adjust your calories we suggest manipulating carbs by no more than 10 grams  per week, until you see the scale move, or you see physical changes in your body.There is no need to reduce carbs/calories and more if you are seeing results. Only change your macros when your weight loss stalls. This means no change in appearance, how clothes fit, or your weight for 10 days. Then and only then can you start changing your macros. There is ZERO reason to change you macros if you are still losing weight!
