Does Fat interfere with Protein Digestion?
Does a meal that contains a high amount of fat (ie 80% fat, 10%
protein, 10% carbs) prevent stomach acid from breaking down proteins (ie meat)? Does dairy (ie milk, yogurt) rely much on stomach acid for it's digestion? Also, if one eats pure fat (ie coconut oil or butter oil), does it require stomach acid or bile for digestion? |

One of the principles of food combination diet styles is that digesting starch and digesting protein are not compatible. Digesting protein takes acid, but acid interferes with digesting starch. The good news is that digesting fat does not interfere with either because it happens at a different point in the digestion. Digesting proteins or starches is something that the body adapts to. Because I normally eat low carb, high fat, my digestion is tuned to that. I can give myself mild indigestion by eating a high starch low fat meal at a delicious Indian ethnic restaurant. Similarly folks who regularly eat near vegitarian levels report indigestion from eating steak. Switch the type of food you eat and if the dchange is large enough it can trigger several days of indigestion. It's temporary. Does dairy (ie milk, yogurt) rely much on stomach acid for it's digestion? I don't know. Cheese needs acid because it's go plenty of protein. Also, if one eats pure fat (ie coconut oil or butter oil), does it require stomach acid or bile for digestion? Bile, and that's why there is not conflict between digesting high protein and high fat foods. In the stomach acid is used to break down the protein. In the duodenum bile is added. The bile neutralizes the acid from the stomach (hmm, could this be the source of lots of burps?) and it also emulsifies fats. So the good news about a high fat diet is it exercises the gall bladder by making it release bile after each meal. The bad news about a low fat diet is it fails to excerise the gall bladder so gall stones tend to form during a low fat diet. The confusing part is switching from a long phase of low fat to a low carb diet starts exercising the gall bladder so it can break lose existing gall stones. Prevention it's the same thing as a cure. Unless the existing gall stones are small enough that they pass without injury. Chuckle - Life long low carbing is good for the gall bladder. |

... digesting fat does not interfere with either ... ...*Switch the type of food you eat and if the change is large enough it can trigger several days of indigestion. Thanks Bill and Doug. I recently switched from a low-fat to low-carb diet. I have tried twice before but couldn't stick to them due to dull headaches, lethargy, sore nerves and high cholesterol levels (+400) even though I am quite thin (BMI = 18.3). I hope it will be different this time with lower protein and higher fat. The second morning, I had a bad headache but it went away. About a week into and the lethargy has gone done but I still feel it especially during exercise. The new diet seems to have reduced heartburns but inflamed cuticles on sides of finger nails. I am also hoping the low-carb diet will help my trigger fingers which I experience upon waking. Did you experience an increase in inflammation initially? Did it go away? |

What are you calling a low carb diet?
Fitday shows I am eating between 35 and 105g of carbs mostly from veggies, about 50g of protein and the rest is mostly butter. Be sure to eat plenty of veggies, and get your omega3 (fish oil, purslane, ect). You may want to try an antiinflammatory tea as well For some strange reason, when I have eaten canned salmon, it also caused the cuticle areas on fingers to become sore. I'll have to retry or else get some capsules. |

I recently switched from a low-fat to low-carb diet. I have tried twice before but couldn't stick to them due to dull headaches, lethargy, The first two weeks of a low carb plan ends up a detox plan. There are all sorts of effects that end by the time the two weeks are over. Headaches are a common one - Dietary carbs directly cause the release of insulin and insulin causes water retention. Plus the brain works very well on fat as fuel (siezure disorders get treated with ketosis) but normally burns glucose as fuel. I suspect the fall in insulin triggers lower blood pressure and that effects muscle tension in the head. There's also the fact that some low carb plans say to go off caffeine and caffeine withdrawal includes headaches. If it's sugar and blood pressure related the headaches are gone in a week. If it's caffeine related it can take two weeks. Changes in energy level are common when going into ketosis. I get a huge burst of extra energy rather than lethargy, so the energy changes can go either way. Again it lasts under two weeks. sore nerves I don't know what that means but it does not sound familiar. and high cholesterol levels (+400) Cholesterol readings are to be taken before starting and after being on low carb 2+ months so this statement makes no sense. If you are getting cholesterol measured more often than that it's the same issue as getting on the scale more than once per day - Deliberately attempt to reduce good information to noise by inspecting the drift and the result is viewing noise as useful data when it's not. The total number isn't a useful number. Look to the high-low ratio and the VHDL count. There are two different claims about the most predictable effect of low carbing - lowered blood pressure and lowered VHDL count. Both are true, just a matter of which happens the most. But the time scale isn't week to week. even though I am quite thin (BMI = 18.3). So you're low carbing for the health benefits? Nice. I hope it will be different this time with lower protein and higher fat. Run the arithmetic on total calories, carb grams, protein grams, and fat grams and low carbing done by plan is always high fat. My maintenance numbers look like this - Target weight is 180 lbs, target calories is 1800. Atkins CCLM maintenance carb quota is 100 gm, 400 cal. 1800 - 400 = 1400 remaining calories. Simple estimate for protein grams is 100 gm, 400 cal. 1400 - 400 = 1000 remaining calories. At 9 calories per gm that says my fat target is 1000 / 9 = 111 grams. In actual practice I end up above 100 grams of protein by trading down some of the fat. It still ends up with a 3-digit fat gram count. The second morning, I had a bad headache but it went away. Early. Nice. About a week into and the lethargy has gone done but I still feel it especially during exercise. While low carbing the glycogen supply is reduced. Doing a heavy workout can easily deplete the glycogen stored in the muscles and with little or none left in the liver there's no new supply for the muscles. I suggest trying longer milder workouts instead of shorter more intense workouts. Then over time build up as your muscles grow more fat burning slow twitch fibers. The new diet seems to have reduced heartburns but inflamed cuticles on sides of finger nails. In another post you mentioned that eating salmon causes inflamed cuticles. I say now that you know salmon is a personal poison food do not eat it any more. Don't eat foods that trigger ill effects as soon as you figure what what those foods are. I am also hoping the low-carb diet will help my trigger fingers which I experience upon waking. Do you have any idea what is causing the finger spasms? One cause is poor blood circulation that happens with diabetics so it worries me. Low carbing can prevent diabetes, but depending on existing damage it won't necessarily stop the symptoms. A very different if - If you're startling when you wake up it's possible that is related to blood sugar swings. A high carber low fatter will be running low on glucose by the end of a sleep period and could be in a low blood sugar state. That comes with stress hormones to drive up blood sugar and appetite. In comparison a low carber high fatter has a stable blood sugar level from converting fat into glucose so the stress hormones don't get relesaed. It's a big if but if the spasms are caused by blood sugar swings they should stop happening. Time will tell. Did you experience an increase in inflammation initially? Did it go away? For me before starting I had problems from wheat intolerance. By the end of the first two weeks all sorts of symptoms went away. I don't know if they would be called inflammation. Banish that salmon! |

Those round-downs are not going to make a significant change to the top of your intake, just fun stuff about labelling laws. At 35 you can have very large portions of low carb veggies. So much califlower you can hardly eat it. A 105 that's portions of root veggies. Root veggies don't have as much bulk on the plate and in the stomach but they are at least as filling as the lower carb ones. When starting very low, higher carb veggies are more calories so they are more filling. At some point they get so high in carbs they end up making us more hungry not less hungry so if you graph it it's a curve not a line. Early on more is better; later on more is worse. about 50g of protein Why did you decide to go that low in protein? One reason so many folks stay up near 100 grams is there is little need to count animo acids because the total has extra. At 50 it's time to look at amino acid levels to make sure you're getting a full completment. Including some eggs as your protein source likely handles that issue. Another reason so many folks stay up near 100 is it's easier to do the cooking. In the long run amount of effort matters. and the rest is mostly butter. That's fine but I bet it will get boring after a while. Next time out shopping maybe mix it up. Some olive oil, some nut oils. Maybe use some coconut oil or lard in cooking. Maybe get some refrigerated flax oil for use on salads. There's a tradeoff that extra variety is less boring but more work at the store thinking of how to use it. Be sure to eat plenty of veggies, and get your omega3 (fish oil, purslane, ect). You may want to try an antiinflammatory tea as well For some strange reason, when I have eaten canned salmon, it also caused the cuticle areas on fingers to become sore. I'll have to retry or else get some capsules. Put aside the salmon if you think it causes problems. Feel free to double check in a couple of months. You don't want to put aside some type of food forever and it ends up the problem was caused by something else, but once you have double checks that it causes a problem drop that nasty personal poison from your food choices from now until you decide you want to be sick like that again. |

The first two weeks of a low carb plan ends up a detox plan. *There

One cause is poor blood circulation that happens with diabetics ... As I understand it, trigger finger can result from inflamed tendons that bind trying to slide through pulley like structures. Speaking of spasms, on some mornings when I contract my calf muscles they seem to stay contracted. Is this a magnesium deficiency? Do you taking magnesium supplements? A very different if - If you're startling when you wake up it's possible that is related to blood sugar swings ... This could be as my heart rate does go up considerably upon waking. about 50g of protein Why did you decide to go that low in protein? ... many folks stay up near 100 grams ... You don't want to put aside some type of food forever and it ends up the problem was caused by something else ... In the past, when I ate more protein, my feet would become sore more easily from walking. But then I was eating more carbs also. Maybe low- carb will allow me to tolerate more soon. At 35g you can have very large portions of low carb veggies. So much califlower you can hardly eat it ... Early on more is better; later on more is worse. I wonder if this explains why I have felt drowsy an hour after some meals with approx 100g of carbs but not after approx 50g. In just a week and a half I have lost couple of pounds even though this isn't a goal. Currently this diet has so much fat that it make me queasy and I don't think I could eat more. Nice to have this problem for a change |
