It is a little more than cutting sugar. If you replace all your simple sugar with complex sugar you will have an improvement in blood sugar control, that is true. You won’t reverse insulin resistance with that change because you will still have elevated insulin levels all the time.
What ketosis allows is a period of time where you are not using large amounts of insulin to push your blood sugar down to safe levels. Instead you use gluconeogenesis (making sugar in the liver from fat) to push blood sugar up. This means you don’t overshoot and have to push it back down.
If you stop using insulin all the time your body becomes less resistant and it becomes more effective, allowing you to actually push your blood sugar down when you need to. This is one of the core issues with diabetes and can actually be solved.
As for your wife’s mum, what she is eating is up to her. She is an adult and has to make her own decisions. If she chooses something you wouldn’t choose it isn’t an indictment of your and your choices. She can do what she wants and so can you. It isn’t a personal insult. If she chooses to take keto very seriously and won’t eat beans then treat it like you would vegetarianism, don’t be dismissive or rude, just be a supportive person and don’t make bean (or other high carb) dishes when she is around for dinner. Or make the high carb dish as well as something for her. Or just make parts of the meal keto and others high carb and mix and match on your plate. Or don’t have her over for dinner. Lots of options that don’t require you matching her diet or pushing back on what she eats.
Diet is personal. It is personal for her, and yours is for you. Her diet is not personal for you. You don’t need to concern yourself with her choice of food just like you don’t need to be concerned with her choice of underwear.
















Just a quick clarification. This is a mouse study. This is not a study in humans.
What do mice eat? What do humans eat? Are we closely related to mice? Do we occupy the same niche? No. This tells us about mice eating a ketogenic diet, not about humans doing so.
Monkeys exaggerate, mice lie. Something shown in primates is likely, though not guaranteed, to be similar in humans, though the degree may be very different. Something shown in mice may or may not replicate in humans at all, and the degree is often very different even if it does.
Mouse studies are great in some ways. They are cheap, fast, and very well understood. You can copy the study design from someone else and save a lot of effort designing your study. You can control for really specific factors by choosing what specific mice you use. You can control their diet perfectly, use large numbers at low cost, and see their full life cycle in just a couple of years.
Mouse studies also suck in a bunch of ways. Humans are not mice, so translating the research is not easy or reliable. Something that causes an issue in mice may or may not translate to humans for a bunch of reasons. They make their own vitamin C for example, so you may have to knock out their genes for making vitamin C if you want to make them get scurvy. You have to humanise them and these changes are always approximations.
So this study does show that a high fat diet that causes obesity IN MICE does increase tumorgenesis in the small intestine. In mice. Not in humans. Every claim here needs that caveat to be made clearly and directly. If they do a translational study in humans I will happily read it, but this study? To me it is worse than useless. It is irrelevant at best and misleading at worst.
