One thing I never see mentioned with keto is the fact that several studies have found a potential link between a high intake of saturated animal fat and colon cancer, which is the third most common cause of cancer deaths in the US. I say potential link because the causation has not been definitively proven, as it has been with cured meats and alcohol (both of which have been proven to elevate colon cancer risk). I am BY NO MEANS saying that keto raises your risk of colon cancer. But if you have any family history of colon cancer, I would think twice about keto.

Can you please post links to these studies? I have a family hx of Colon Cancer and my GI doctor is very supportive of me following a Ketogenic Diet and I've never heard of this alleged connection. I don't drink and don't eat a lot in the way of cured meats other than some bacon occasionally, so I'd love to read some actual scientific studies about this. I worry that this is just Keto-fearmongering by a community that just doesn't know much about it. FTR my grandfather who died from colon cancer, was not a drinker and to my knowledge was not following a Keto diet.

I think it's red meat rather than sat fat, and with everything in nutrition it is hard to separate out causes, but personally I think it's enough to limit red meat. Here's a discussion (along with other topics) with links to studies; http://theoncologist.alphamedpress.org/content/5/5/393.full

I also limit sat fat, but will note that one can do keto without eating a lot of red meat and without a crazy high amount of sat fat.

The 20-30% relative increase in colorectal cancer is processed meats (bacon, sausages, etc...). The is no increase when it relates to red meats like beef.

I wasn't referring to the processed meat thing. I was referring to this, from the link I posted:

"National rates of colon cancer are also strongly associated with per capita consumption of animal fat and meat, with correlation coefficients ranging between 0.8 and 0.9 [32, 35]. Based on these epidemiologic investigations and animal studies, dietary fat increasing has been hypothesized to act by excretion of bile acids, which can be converted to carcinogens or promoters [47]. However, many studies have found that higher levels of physical activity are associated with reduced risk of colon cancer [48]; thus, the high rates in affluent countries previously attributed to fat intake are probably, at least in part, due to sedentary lifestyle.

In a meta-analysis of 13 case-control studies, a significant association between total energy intake and colon cancer was observed, but saturated, monounsaturated and polyunsaturated fats were not related to colon cancer risk after adjustment for total energy [49]. The relation between diet and colon cancer has been examined in several large prospective studies, which have not confirmed the positive association with total energy intake seen in case-control studies [50-53]. Higher intake of various forms of red meat has been associated with greater risk of colon cancer in most prospective studies [50-53], but not in all [54]. In general, positive associations have been most consistently seen when red meat was specifically examined and when eaten as a main dish. Fairly consistent positive associations have also been observed for processed meats. The apparently stronger association with red meat compared with fat in several recent cohort studies needs further confirmation, but could result if the specific fatty acids or nonfat components of meat (for example the heme iron or carcinogens created by cooking) were the primary etiologic factors. This issue does have major practical implications as some dietary recommendations encourage daily consumption of red meat as long as it is lean [55]."

And the cited studies are at the end of the link.

I seemto stay full longer when I have more fat in my diet than without. For those of you that have done or are doing keto, would you recommend it? What do you like/ dislike about it?

100%, especially if you're (A) Type 2 diabetic with poorly managed blood glucose or (B) have 50+ pounds to lose. I started at 237.5 lb on January 1st. This morning I was 191.5, so that's 46 pounds lost. Just had my six month checkup and my labs are great. A1C is down from 8.1 to 6 (!) and my triglycerides are half what they were in October. My diet is full of whole foods and good, healthy fats (lots of butter, eggs and heavy cream), I feel great, I sleep better and I never get hungry or have cravings. Keto is the best decision I ever made.

First, I said “potential link” because the science is not definitive. If you do a Google search on “saturated fat and colon cancer,” you will find pages of information discussing this topic, including some scientific studies that cite a correlation between high saturated fat intake and increased colon cancer risk, and other studies that show no correlation. Some agree that while obesity is a clear risk factor, fat intake itself cannot be singled out as a cause. So, as with many other studies of cancer and diet, the data is not definitive. As I said. Do your own research, and work with your doctor. As for me, my father died of colon cancer, and I have already had one large precancerous colon polyp removed, despite exercising and being fit most of my life, never being obese, and eating a “regular” amount of cured meats, moderate alcohol and the amount of saturated fat found in a typical Western diet. As the science is unclear but some science indicates that a high intake of sat fat MAY be a risk factor, I am choosing not to take that risk for myself. But everyone should decide for themslves, which Is why I said “think twice about doing keto” rather than “don’t do keto.”

ETA my father was obese, drank moderately, did not exercise and ate a diet very rich in saturated fat.
