Isnt 1900 cals a lot for a woman?
Adult population need very small amount food! I do weighttraining/cardio 2 houers/Day 76-7 days/week dosent belive I eat more than 2000kcal...I Bicycle to the gym, eat clean, dosent have a car.
If your not on drugs or doing endurance sport on national level your body is totally shut down! Especially after age 30...u need to cut the food to half and double your training time!
Look around you, 99.999% of allpeople are fat! Fat = no visual abs = more food than they need!
Your girl should eat maximum 1000kcal!
