Hi, PEPPERMINT131 -- I'm not entirely clear about your question; first, it's my understanding that a BMI between 19-24 is considered in the "healthy weight" range, so you would not be overweight at a BMI of 24, but would be in the high-healthy range so I'm not clear why you want to "get calories up without affecting carbs and fat." It does appear that you need to eat more lean protein -- the USDA recommendation calls for 10-35% protein, 20-35% fats (less than 10% saturated fat), 45-65% carbs.
You might want to send your question by Spark Mail to Coach Tanya, one of the HBP team co-leaders.
