Your diet is wrong- fats are not the issue.That is why is isn't working. The issue for you is most likely hormone (estrogen) dominance.The other thing that causes gallbladder issues are insulin and choleserolcan. It could be one of these or a combination of all three.
Corn and SOY products create estrogen dominance issues. Processed foods and grains, (frozen ,canned, boxed, and bagged)... are full of these products and create estrogen dominance.
99% of all manufactered foods have one of these two in them. There are a slew of alternative names for them as well, so go online and find out what those names are. Watch labels for these products.
Same with insulin! You need to get away from the grains and processed foods , and high carb diet- that will keep insulin high!
You should be eating a low carb diet with high protein and a fair amount of saturated fat. Hormone free GRASS FED meat and chicken, wild fish, and vegetables. Eat raw fruit, only at dessert, after the meal, to help keep insulin down.
Saturated fat in the form of butter, raw virgin coconut oil, and virgin raw red palm oil are the precurors to create progesterone, which will balance out the estrogen. If you cant find a way to cook with coconut oil- then eat a T or two a day, right off a spoon. Raw seeds and nuts (except for flax)should be comsumed and do not limit them- try to find someone with a tree because the nuts in the store are now irradiated.
Then- take magnesium malate supplements. At least ###-###-#### mg a day. It can cause a loose stool, if it does you cut back the dose a little until comfortable.
Magnesium can help balance out the insulin issue, and it is also probably low in you , since you eat high grains. Magnesium is very important to the fetus and mother and normal delivery. Also take a b liquid complex under the tounge.
