So I ate a packet of Thai noodles and they said on the nutritional contents and online 75kcal per 100g of prepared product (the packet is 90g)- then after I’d eaten them I scanned the barcode into My Fitness Pal and it came up 400+kcal for a 90g packet ?! Have I just eaten 400 calories or 75? I don’t know what to eat for the rest of the day. Which number would you go with?
