I would not have any beans (loads of sugar) or chips....
Give her at least 4 steamed vegetables with every meal, and reduce pasta, potatoes and rice to reasonably small portions, make sure meat is lean ie beef or chicken or lamb, but not fish fingers or burgers. cook fish filets rather than fish fingers, more nutricious and very fast to cook.
I have a ds who is prone to being chubby, and have had to accept that other than a saturday pizza night, he has to have fresh food every evening, no processed anything..there are so many 10 minute recipes..
When he comes in and sits down for his homework, l put a plate of crudite and nuts beside him to nibble on to take the edge off his apetite. ( which is huge)
Each meal however quick, has the obligatory 4 or 5 steamed vegetables to fill him up ...... l only keep very little desserts in the cupboard, ie just one pack of biscuits so l can keep an eye on how much he has.
I don't discuss weight, just make adjustments quietly...we don't have anything except water to drink, l only buy cordial or fizzy drinks for parties and get rid of any over!
Sugar is the enemy and is in everything even bread, and M and S ready cooked chicken breasts!!l try hard to have bread free days...same for cereals, could she have porridge for breakfast with blueberries/ strawberries?
