Most bakeries use commercial yeast in addition to starter in what they call sourdough. If you haven't already been doing this, you need to ask if there's commercial yeast in their sourdough. You might need to shop around to find a bakery that does it pure. My partner has a similar condition (not celiac, not gluten sensitive, but 'something in bread' sensitive) and she found that sourdough from locally made starter wa…

It's hard to not start a starter with yeast and can be dangerous to not use a commercial yeast to keep a starter going. If the conditions are not right or it's not a safe yeast colonizing your starter it can be deadly. I don't have a strong opinion about the origin of the starter. It will definitely influence the flavor of the bread but other than that I don't think the origin is important. More important is the rise…

I heard a crazy thing last year that there's a wasp in France that harbors one of the yeasts that flavors the wines of the region. The wasps, while a pest, also end up inoculating the vines and grape skins with the 'right' kind of yeast.

While I don't think a ketogenic diet is an optimal diet in terms of longevity or overall health (as all blue-zone diets are carb rich), it does appear to confer some benefits in the short term which are fairly compelling. The vast majority of humans are adapted to seasonal eating, with high carbohydrate diets during spring, summer and fall, and very low carbohydrate diets during winter (or during the wet/dry seasons)…

Out of curiosity, are there any areas with a fat rich diet, which has good access to quality health care? It seems most cultures, which aren't based around hunting and gathering, have a carb based diet, as it's simply the most feasible for supporting a large population.

Maybe France?

Keto isn't a fad diet at all, if a fad diet is one that you do for a while to drop weight quickly. I've been on Keto for about two years now, and plan to eat this way for the rest of my life. I've gone from 235 to 180. Going from 245 to 235 took forever on a "normal" low fat diet. My A1C and cholesterol have greatly improved.

He said eat normal and healthy, not eat low fat; low fat is also a fad diet. And yes, keto is a fad diet with no empirical evidence to support its claims, testimonials are not evidence. There was actually a recent scientific study done and it found keto claims lacking. I've done keto, I'm well aware of what it is, but the weight loss is far more likely to come from eating less than from not eating carbs because it's…

"plenty of veggies and fruits" "cut out sugar"

You can't do both.

That is wrong, the ketogenic diet is prescribed by doctors to patients suffering from seizures and it works. There are long term studies and the NYTimes has been reporting about this since the 90s. http://www.nytimes.com/2010/11/21/magazine/21Epilepsy-t.html Everyone picks a diet. If you just randomly eat anything thats available to you, in the developed world, you are most likely significantly overweight and at very…

Prescribing it for epilepsy doesn't necessarily make it a healthy diet for your average individual as you are looking for different effect from the diet.

Very good point. I didn't mention it, but I am eating garlic stuffed olives for electrolytes and fat. edit: forgot to mention too that I make the protein shakes with almond milk which has a few grams of fat per serving as well.

May I ask exactly how the garlic is treated and exactly what olives you are eating?

I like Mezzetta. Ingredients: Olives, water, garlic (cloves), sea salt, lactic acid, sodium bisulfite, and "natural garlic flavor"

They are large green olives from Napa Valley. I'm not that knowledgable about olives so I can't say more than that.

There is at least one person in these comments extolling the virtues of keto viz a viz quick weight loss without exercise. I don't know what a normal low fat diet is, but the overruling factor in weight loss/gain is the ratio of work (exercise) to energy input (calories).

Physics, years of evidence and common sense down voted on HN where solyent is seen as a good thing.

If we're sharing anecdotes here, I've also tried a ketogenic diet for about 2 months. I wasn't trying to lose weight, I was just curious what it was like. The only change I noticed was I became slightly weaker, lifting only about 90% of my previous weights. But this might have been placebo, because I had already heard that it could happen. I stopped the diet because it made cooking and eating difficult for no obvious…

In my experience I am actually stronger and have more stamina. I will actually blackout during workouts if I am eating carbs. On keto I have not had one incident.

There are some great resources on the keto subreddit (reddit.com/r/keto). I personally had similar issues when I first started keto - several times a week i found i had to be conscious of my electrolyte intake and would supplement with broth and often almond milk (potassium). However 6 months in I've found it's less of an issue, even at lower electrolyte intake, but I'm not sure why. I never found the need to hit the…

That's what I'm worried about. Taking in too much and simply the hassle of having to mix salted water every single day.

I take ZMA and potassium daily. I will drink electrolyte water too. When I get home from the gym and feel drained I will drink 8oz of chicken broth for the salt. I had some severe cramps before starting this.

You're stuck in the mindset that fat makes you "fat". This is the whole point of ketosis, and a rethinking of wrong dietary guidelines that have persisted for decades. The butter in the coffee supplies fat for fuel / energy, suppresses appetite, and does not contribute to weight gain or more specifically an increase in adipose fat tissue. Simply cutting all calories is futile. Your body needs energy to sustain itself…

But adding calories in whatever form still means more calories in than not eating them. Edit: I get the point that it stops hunger, but my point still stands, and the parent posters still doesn't make a great deal of sense.

The point of putting butter in your coffee is to extend your natural faste. The faste that you enter every night during sleep. It is done in tandem with also skipping breakfast on keto.

The reason you put butter in your coffee instead of a spoonful of say, sugar, is that fat takes a long time to digest and even a fairly small amount of it (a table spoon of butter in your coffee) takes a while to digest. During that time period your hunger sensation is suppressed.

Coffee also promotes weight loss because it speeds up your metabolism. The idea behind buttered coffee is fairly simple. Put enough fat in your coffee so that you don't get hungry and eat a meal and you help extend your natural faste - and your morning coffee helps speed up your metabolism.

There are good reasons for drinking buttered coffee even if you're deliberately trying to avoid weight loss i.e you are following a net neutral or net positive caloric intake diet. When you're fasting your body isn't spending energy digesting food which means less of your body's immediately available resources aren't spent digesting food.

Even if you're getting calories from your coffee it doesn't impact your weight loss because you're still eating less calories than your body needs to maintain the weight.
