Cannot seem to tolerate high fat diet but seem to need more carbs..?

5 Replies

I've read a lot about how good saturated fat is for us, and some diets even advocate that 80% of the daily calorie intake should come from saturated fat.

However, I have tried some LC recipes, containing a lot of high fat cream, sour cream, cheese, and bacon, and they all tend to make me feel queasy. On the other hand, eating a fruit salad makes me feel great, even if I include high GI fruit like banana, melon, or pineapple.

How come some people say they got their life back on a high (saturated) fat diet, and eat bacon dipped in melted butter all day long while feeling great, whereas I can hardly stand any saturated fat at all...? I do much better when I restrict my intake of saturated fat and always eat fat with protein and (low GI) carbs.

Has anyone else experienced this?

Maybe you don’t tolerate dairy? And bacon you can take or leave. There are plenty of low carb meals that don’t involve dairy or bacon.

The low carb, high fat diet does not contain exclusively saturated fat. This article about fats, oils and sauces might help :

And another comment... Any food which contains saturated fat also includes monunsaturated fat and polyunsaturated fat. And the only food which contains more saturated than unsaturated fat is dairy. Info courtesy of Dr Zoe Harcombe PhD in the following video from about 12:00 onwards.

I'm trying (and often failing because of a sugar addiction) to eat a LCHF diet, and at least for the first few months I felt queasy too. I've had an entire lifetime of my cells using glucose as an energy source and I found switching to fat rather difficult. I think in my case some of the queasiness was psychological.

One thing that doesn't help is that people lose electrolytes (like salt, for example) as a result of switching to fat as an energy source (and lowering insulin requirements). It creates the condition known as "keto flu". This condition makes people feel lethargic and tired, and causes brain fog, often gives people cramp, constipation and makes it hard to sleep. To overcome these effects increasing salt and other electrolytes can help a lot.

I have discovered that a higher intake of fat helps to reduce the brain fog I've had for years, so I'm not prepared to reduce the amount I eat now.

We're all genetically different, so we can't assume what suits someone else will be good for us. Eat what suits you best providing it's healthy & unprocessed, & not too high in sugars, refined starch, & salt.

It can be because you have been on a low fat diet for so long and so your gall bladder isn't producing enough bile to deal with the fat.
