My daughters 14 she's 4'11 and 140 lbs. she wants to lose weight. she does kickboxing 3 times a week. how many calories should she have per day?

Prob apx 1450 kcal/d: But make sure these are healthy calories! eating a lot of veggies, whole fruit (not juice) real grains like oats w plenty of fiber, and plenty of lean protein can help. Dont forget calcium & water, & limit foods & drinks w processed sugar. Liked robt lustigs website re sugar & book fat chance. Some may be influenced by if she's had her growth spurt. Check w pcp if concerned re thyroid, etc.
