Keto Diet with weight loss surgery - What are your thoughts about it?



Recommended Posts

I do modified keto - cut out all sugary and starchy carbs (sugar, rice, potato, bread etc) but eat whatever fruit and veggies and legumes I like. So, not really true keto but keto-ish. Facing said that, I've just started the Jan challenge and want to keep my net carbs under 50 a day so that means no fruit most likely.

I get really confused about this. I understand that being in ketosis means you are burning fat for fuel, but isn't the bottom line calories in, calories out? I am in ketosis by default now because I am early out and just can't eat much of anything, so even with no real attempt to avoid carbs, I have very few grams of them. If someone ate 500 calories of carbs or 500 calories of Protein and fat, wouldn't they lose with both?

So CICO (calories in/calories out) isn't a purely valid concept according to the biochemistry. But let's pretend it's close enough for government work. Ok?

In theory (and this is from one of the leading Keto docs who trained under Dr. A.) keto IS putting our body in fat burning state rather than being a sugar burner. There is between a 200-400calorie advantage for doing that because it takes more energy to convert energy from protein/fat than it does to burn sugar. But still..that's sorta insignificant.

What keto is great at is making your feel energetic so you move more! (This is after you get past the 2 week keto flu.) Also, it's a great appetite suppressant. So the deeper into ketosis you are (ie the more ketones you are burning for fuel), the lower your hunger. AND the fewer your cravings (lower your head hunger). So by defacto, you DO end up eating less. And he said, that's what they want you to do! They want you to naturally moderate and reduce your calories!

So it really isn't a "free for all" food fest. It's only EVER been intended for people to eat just to the point where hunger is abated, but not to fullness. Sound familiar? Sounds a little like our weight loss surgery rules. Yes? This is part of why I think WLS + Keto/Low Carb = Match Made In Heaven. Why not reduce your hunger as you eat healthy healthy and take in as few calories as you can without the pain of hunger?

I did Keto last year and lost 30lbs and felt great! Took a cruise and of course totally bombed Keto so I thought I get back on when we got home. I tried never really got back into it. I ended up gained 45 lbs back and got a kidney stone from the diet because I only have 1 kidney and I should have never done the diet. It works but only if you are going to stick with it. From my experience please make sure the diet is safe for you!
Once I got sleeved I am watching my carbs but I am not getting into Ketosis! Good Luck!

It looks like you have lost 22 lbs in less than a month. Since ketosis is your body using fat stores for energy, it would appear that you are in ketosis, to me.

I am not in Ketosis. All my Jell-O and popsicles have sugar in them and I was eating cream of potato Soup just to make sure I stayed out of it. I drink a strawberry Snapple everyday as well and have since surgery. Also I should say I have left over Keto Strip that you pee on just to make sure!

Even if you are consuming sugar/carbs, you are not consuming enough to keep yourself out of ketosis. By definition ketosis is "When the body does not have enough glucose for energy, it burns stored fats instead",

So you maybe feeding your body foods that convert into glucose, but it is not sufficient, so your body is using your fat stores as well, hence your 22 lb loss in less than a month.

I don't call myself "keto" although I am not only by virtue of low carb dieting, but also cuz of low calorie diet. I'm in dietary ketosis (aka producing ketones and using ketones/fat for fuel).

I have issues with the high fat of the current keto model, so I do a more moderate fat diet. My numbers are more: 30% P, 55% F, 15% C (or for 850cals I get: 64g Protein; 52g Fat; 32g Carbs (total, which nets to around 20g from veg etc).

It sure works for me. I also IF to further reduce insulin resistance and assist with fat loss and autophagy.

Do you use a blood meter to check your ketone level by chance? I'm curious what hardcore ketosis looks like post-op vs. pre-op just eating keto. Currently I keep my ketones at about 1.7 - 2.0 mmol and it is VERY hard to keep this up. To measure blood ketones I have a KetoMojo meter.

I'm not "hard core". LOL, see? I said so in that statement. I don't claim "keto". I am LC. We just got one for Christmas but I haven't wanted to blow into it until I'm sure I'm over my cold. Those levels are very hard to maintain.

Meh, potato/potatoe...you're in ketosis, it's measurable. In order to be in ketosis you simply have to eat less that 20-50g (high side) of carbs a day AND avoid sugar, which it seems bypass patients do naturally (unless you still manage to pound back Cheetos and soda lol). No one will crank out ketones by eating that junk.

I'm curious what level of ketosis bypass patients have achieved by not actually trying, just following a low carb diet, like you. Most folks tend to cut sugar anyway to avoid dumping so the minimal amount consumed by a post-op person eating by the book most likely isn't enough to knock you out of ketosis, if so, not for long. See what I mean? To me, someone with bypass, eating as they should, should easily be able to achieve "hardcore" nutritional, if not near therapeutic, ketosis just by barely eating bad carbs or sugar.

But one can achieve ketosis by consuming very low calories, not at all dependent on the source of said calories

If I were to eat 100 g of pure carbs a day, and nothing else, that would be 400 calories. My BMR is around 1300 calories. With that large of a calorie deficit my body is forced to use fat stores for energy, and I would therefore be in ketosis.
