I have been told by my GP to eat a maximum of 3g fat per 100gm.

How can I measure this using the app?

Thanks in advance.

    I'm not sure if it's a typo or just a measurement I'm unfamiliar with but what is "gm"?
    And per 100gm of what?

    Sorry, 3 grammes of fat per 100 grammes of food.

    Do you mean that the GP wants you eating only a 3 percent fat diet?

    Probably, doing the maths.

    that is an odd target,

    usually fat recommendations are based on grams per lb of body weight, or % of calories consumed

    You are sure it was not meant for you to eat 30 percent? 3 is really really low.

    No, as % has to do with calories, and some of that 100 grams of food would be water and have 0 calories. even if the other 97 grams had cals that would be (3*9(97*4 + 3*9)) = 6.5%, but more likely 15-30% depending on the cals in the food

    Ah, got it. That is a weird way to measure. The food diary doesn't total your grams of food, at least not that I know of. But yeah, that sounds like 3% fat, which is crazy low!

    Although if you figure 3g of fat = 27 calories, and the other 97g of food are 4 calories so 388 calories, 27 is 6% of 415. I'm really not sure if that's the right way to look at it or not though.

    Edited to add: now I see @erickirb posts and my calculations above do not include water, so that math won't be right. I'm stumped. I'm not sure there is an elegant way to track "per grams of food".

    I understand what I was asking was not correct I was just trying to see if the OP misinterpreted the requirement.

    Think you really need to clarify what the Doctor is actually suggesting you do (and why) as that is a peculiar goal and an extraordinarilly low level of fat.

    So if you eat 2 lbs of food, consume 27.24 grams of fat, regardless of the % of cals it makes up?

    Are the nutrition labels where you live based on 100g? If so I would think that you could just look for food that has 3% fat or less per 100g.

    Unless I am just too thick headed to understand...probably so!

    Foods with less than 3% fat would result in a really sad diet, standard 'healthy' staples like chicken, salmon and eggs would be off limits.

    Judging by your use of language I suspect you are in the UK, in my experience our General Practitioners know bugger all about nutrition - maybe ask for a referral to a dietician if that goal is linked to a health condition rather than simply for weight loss. Good luck

    Do the food labels in your country look something like this?

    I'm thinking that your GP is wanting you to shop for foods that say on the nutrition label that they have 3g or fewer of fat per 100g rather than specifically tracking your total intake in 100g increments.

    Not really. Low fat foods are meant to have less than 3 grams of fat per serving which may or may not be 100 grams in size.

    A low fat diet is typically under 30 percent fat of calories.

    What is the goal of this requirement? Are you trying to lose weight or do you have a problem with fat in your food?

    Maybe you've cracked it - 3% per serving although that's different to the photo. Yes, gallbladder problems.

    Even that picture is actually a little over 20% fat, as 13 calories of the 61 cals from fat.

    I think it's a challenging target. A nutritionist might have more time to work with you to get it right and sustainable.

    Best of luck!

    Do ask your doctor for a referral to a dietitian, or whatever you call someone credentialed over there. (Here in the US, "nutritionist" is a meaningless term.)

    My OH had his gallbladder out 7 or so years ago and recovered quickly.

    Either your doctor is confused or you misheard him. 3 g of fat per 100 calories has been very standard advice for decades, based on the idea of keeping your fat macro percentage below 30%.

    That's a good point. Percentage of calories from fat is distinct from number of grams per 100 grams.

    I looked around some more and found this on an NHS site:

    It seems like a shopping/eating rule-of-thumb to bring down overall fat. The percentage of calories from fat over the course of the whole day might still end up around 30%.

    I'd be with you had not the OP subsequently mentioned "gallbladder problems".

    Very low fat for gallstones did used to be recommended:

    https://www.nhs.uk/conditions/gallstones/treatment/

    ...In the past, people with gallstones who weren't suitable for surgery were sometimes advised to adopt a very low-fat diet to stop the gallstones growing.

    But recent evidence suggests this isn't helpful because rapid weight loss resulting from a very low-fat diet can actually cause gallstones to grow.
