Pre op liver shrinking diet, how much fat is recommended?

[tracysteward 4]

I've started my pre op diet which includes meal plan ideas etc, it says the calories and carbs to stick to, but doesn't say how much fat I can have. It just says low fat. I've been having 20g of fat a day (as little saturated as possible) is this too much?

Were you told how much Protein to consume as well? If you were it can be worked out how much fat you are expected to consume.

Between 75 and 100g of Protein.

Okay if you know you total calories and your Protein grams and carb grams you should be able to work out how many calories can be allocated to fat grams.

Say 800 calories, 100gms protein, 50 grams of carbs:

Protein and carbs are approx 4 cals per gram so 800 - (150 * 4) = 200. Fat is 9 cal per gram so 200/9 = approx 22gms of fat.

If 600 calories, 75gs protein and 50gms carb. 600 - (125 * 4) = 100. 100/9 = approx 11gms of fat.

Yes great math! But I would just add, PLEASE follow your doc's specific plan, cuz for most of us, pre-op, 50g of carbs will be WAY too many carbs to effect quick change in the liver volume during that brief 2 week diet immediately leading up to surgery. For most of us, we'd need <20g of carbs.

I was on liquid diet only for the 2weeks pre-op. I honestly wasn't allowed any food at all, just my low carb low/no sugar Protein Shakes to give 80-100g of Protein per day pre-surg.

Which is VERY different than the 1st 6 months leading up to surgery. For that diet, then maybe 50g of carbs would be just fine if most of that is from low glycemic veggies/fruits/seeds/nuts/dairy.
