In terms of coconut oil, there haven't really been any long-term studies done. (that I'm aware of) Coconut oil does raise healthy HDL cholesterol though, for sure, but if you're eating a typical trash diet, I wouldn't incorporate it either. But my suggestion to use it was in conjunction with a non-processed diet, of course. Your body has to have fuel, and absent sugars (including grains), you must have fat.
I agree that coconut oil has its benefits. But it has a lot of saturated fat compared to other oils, which have the same benefits as coconut oil but with less saturated fat.
An unhealthy gut microbiome will have an imbalance of sugar-feeding microorganisms. To restore that balance, it can be helpful to remove all sugars for a period of time while feeding the good guys - added probiotics and prebiotics, the foods they love (natural, mostly plant-based foods). That's my perspective, anyway, and what helped in my personal experience with some health struggles related to digestion, etc.
Sugar-feeding microorganisms don't care if you eat sugar ("unhealthy") or complex carbohydrates ("healthy"). For them it is the same. See, i know what you're saying and i totally agree (plant-based foods are good etc.), but sogar is not the enemy. Almost every gram of sugar never reaches the majority of gut bacteria because it will be diggested in the small intestine, which has a lot less bacteria than the colon. Also about 95% of gut problems come from the colon and have nothing to do with the small intestine, so most people make the wrong conclusion. Having things like diarrhea? It's never the small intestine, it's always the colon. Cramps and pain? 95% colon, where almost all gut bacteria don't even know what sugar is because the small intestine already absorbed almost everything of it into your bloodstream.
Reducing sugar can help people fighting their problems, but often healing comes because their generel diet is much more healthy than before, because if you drastically cut sugar your condition will improve automatically because you need to replace sugar with often way more healthier foods. Again, sugar is not the enemy. Eating like shit (also in regard to your gut bacteria) is the enemy.
TL;DR: I think you're completely right, but for the wrong reasons.
Anyone tried Intermittent Fasting? 16/8. Eat between 12pm-8pm skipping breakfast.....

Might give it a go with some Bullet Proof Coffee
I'm doing it every year for 1-2 months. It's just one of many tools. It will work, like any other fat loss diet, because you consume less calories than you need. In my personal experience it is the best way to lose weight, because it is easier compared to other fat loss diets. I'm rarely hungry during the 16 hours, with 6-7 hours of it me sleeping anyway. I eat between 1 PM - 9 PM. My day starts an 5 or 6 AM and i just drink coffee or water until 1 PM. The main advantage is, that if you're hungry you're only hungry for a few hours and after that you can eat and will be full for the rest of the day (eating healthy things). During most other fat loss diets you are probably hungry for 12 - 16 hours, which i think is harder than doing IF. Additionally you often don't need to refrain and/or restrict yourself when eating out with friends.
Besides that try to eat more protein during you diet, because you will be more full compared to eating more carbohydrates or fat, 20-30% of the calories coming from the protein will "vanish" thanks to thermogenesis and it helps retaining muslce mass.
PS: Technically speaking, if you drink bullet proof coffee during the fasting period, it's no longer fasting because you consume calories.
