Hmmmm....in two minds about this. I confess to laughing at the thought of a kid hiding a can up their sleeve, how big are the sleeves?!
My parents always had chocolate biscuits, crisp, squash (fizzy drinks were an occasional treat) for me and my brother. We didn’t go mad and certainly wouldn’t have eaten 3/4 bags of crisp in one go! One of my friends however had a huge appetite (as did her brother and sister) - all grew up slim and healthy. Again, they had treats like us but ate huge portions and had after-school snacks like, toast/cereal.
Squash is not the worst thing, I buy the Belvoir ones (I’m allergic to artificial sweetners) and just put a drop in, just enough to colour the water. I will not drink tap water, it tastes very ‘chemically’ and when I lived in SE England it was cloudy and looked bloody awful! I normally just drink bottled water.
I’m surprised by the amount of people on here (I’m new!) that say ‘fruit is always available’; it’s also quite unsatisfying (if you’re very hungry, no way is a tangerine cutting it) and has lots of sugar. As a comparison (according to My Fitness Pal), a 50g apple has 16g of sugar, whereas some squashes have no sugar and black currant has 2g per 250 ml (diluted).
I was very overweight last year and sorted it by seeing a PT who also is a qualified nutritionist. He always says an occasional treat is OK. I obviously know that my diet plan would not be suitable for children but I’m always amazed how many people think artificial sweetners are OK and don’t think sugars in fruit matter.
