Thin Chips (McDonalds)
Surface Area = 0.5 x 0.5 x 2 + 0.5 x 11 x 4 = 0.5 + 22 = 22.5
Volume = 0.5 x 0.5 x 11 = 2.75
Ratio = 22.5 / 2.75 = 8.18
Thick Chips (Chip Shop)
Surface Area = 0.75 x 1.5 x 2 + 0.75 x 6 x 2 + 1.5 x 6 x 2 = 2.25 + 9 + 18 = 29.25
Volume = 0.75 x 1.5 x 6 = 6.75
Ratio = 29.25 / 6.75 = 4.3
Comparison
These figures indicate that the thin chips have 1.9 (8.18 / 4.3) times as much surface area for any given amount of chips which means that’s how much more fat sticks to the chips! Thick chips are therefore less calorie dense than thin chips.
Can you believe I forgot to have chips on Monday – it’s part of my eating regime – I follow Natural Low Density Eating principles which in summary means:
– No process food (ie no biscuits, cake, pie, sausages, etc)
– No added sugar
– No added fat (no frying)
– No milk products (these are processed foods and lactose blows me up)
– No wheat products (these are made from highly processed wheat flour and gluten gives me arthritis)
but I do allow myself chips twice a week providing they are big ones which have a lower ratio of surface area to volume and therefore retain less fat from the frying. Also this way of eating is so good at keeping my weight down I have a third of a bar of dark chocolate every night to avoid losing weight – and because I like it of course – it is otherwise known as the love drug! Lol
So I went into Gosport today (Tuesday) instead and had my chips at the chip shop by the ferry – only £1.70 for an enormous bag! The Gosport market is on Tuesdays so I still got my market/chip day! 😉
