We based your target calorie level intake roughly on your current bodyweight in pounds x 16. Calorie intake is not an exact science and there are many ways to arrive at it. The key is to start implementing the nutrition plan, and then track your results weekly.
In our experience, for 90% of people, the suggested calorie intake that’s based on bodyweight works very well. There are some customers who may need to eat slightly more or fewer calories. After 2-3 weeks, if your weight does not increase at all (and you don’t look leaner too - because you can lose fat and build muscle), add an extra snack to your daily meal plan. If you find that you’re gaining fat, then take away a snack.
