Third fast almost over and weigh in tomorrow which I’m looking forward to. Today was breeze but gagging for a glass of wine….there’s always tomorrow.

Question – everywhere I’ve read tells me 1 gram of Carb = 4 calories but I keep finding contradictions to that in the FD book and on on-line calculators. I’m figuring it could be a brand issue….certain brands varying to others but how safe am I doing my own calculations using 1 = 4?

Example tonight – Can of Tuna on the tin Carb total per 100gms = 2.7 which would equate to 10.8 calories wouldn’t it……look’s way too low to me.
FD book Can of Tuna 108 calories…big difference. The brand I have is brined in spring water and 98% fat free but still a massive difference in my mind.

Any helpers

Hi Iwant2Bincontrol,
Thanks for the reply. I’m trying to find out the best way to work out Calories from a food label that doesn’t have Calories stated. From what I have read 1 gram of Carb equals 4 calories. As an example my can of Tuna says 2.7g total carbs per 100g. From that I calculate to 10.8 calories but it seems very low to me (although it is a low fat brand in spring water brine).
In Michaels book he has a range of basic foods listed and there calorie content per 100g. I understand this would be a guideline for packaged foods as brands would vary. For 100g Tuna he has listed 108 calories per 100g.
Thanks for your help.
