I do a lot of rock climbing, so most of my body is muscle. I'm currently floating at 170 lbs, but would love to lose 10 lbs so I can get up the wall faster. I think that fasting might be foolish because my body needs energy for climbing. In fact, if I wait too long after eating lunch, I tend to get really hungry during climbing and I start yawning a lot (not sure why).

Might be lacking glucose; I believe that is why marathon runners eat glucose before they run.

Some corrections from the point of view of an endurance athlete (triathlon). First of all you don't really "eat glucose", that would be an oversimplification. Glucose is produced by your own body when metabolizing carbohydrates. As a backup mechanism your liver can also produce glucose by converting amino acids (muscle) and even fat, a process known as gluconeogenesis.

Now, if we replace "eat glucose" with "eat carbohydrates", then the statement is still not quite accurate. Experienced marathon runners (and other endurance athletes) will not consume carbs before the run because doing so would spike insulin and effectively shut down breakdown of fatty acids in the liver. Liver can more or less either convert glucose to glycogen and fat, or break down fat, and is not great at doing both simultaneously. Maintaining fat metabolism is hugely important when going the distance since it's the largest energy reserve available in your body (50,000+ calories vs Marathon runners consume moderate amounts of carbohydrates DURING exercise when insulin response is blunted. The idea here is to maintain glucose levels and avoid going into hypoglycemic state (low blood sugar). Ingesting moderate amounts of simple and complex carbs during exercise spares glycogen without necessarily spiking blood glucose to where liver has to regulate toxicity. This way you can keep on going longer.

Carbohydrates do not make you fat. I am eating a high carb vegan diet and have lost 63 pounds since last October.

I do not restrict the amount of food I eat. I snack and have big meals.

Carbs do not make you fat. Eating high caloric density foods makes you fat.

Most people find that their alertness and focus improve significantly on keto. The trick is that a) it takes quite a while for your body to get adjusted to ketosis. 6 months to fully adjust, but the primary adjustment will take at 2-4 weeks for most people b) during this adjustment period, you'll usually feel like shit. since you're running empty on the fuel your body is used to. but many people cheat, or accidentall…

I wonder if anybody on Ketosis has ever done an endurance event and not ended up feeling absolutely miserable/exhausted. I was on a fairly low carb regime ( The research that I've read says that the ideal training regime is to work-out in a carb-exhausted state, so as to encourage your body to develop the low-carb metabolic pathway, but for actual endurance events, definitely carb load as your primary fuel.

I've been training for triathlons while adhering to a ketogenic diet since October 2015. Initially I struggled. It definitely felt like a step back. Over time my body adapted and 3-4 months later I was performing on the same level without consuming copious amounts of carbs as prior to going keto.

These days I can wake up from a 12-18 hour fast and run a marathon at an easy pace while ingesting zero carbs in the process.

I ingest some carbs during actual races when glucose utilization is higher due to higher intensity. You will always need some glucose and the ratio of fat/glucose metabolism depends on intensity. Basically if you push the pedal to the metal your body will utilize what it has got. With that said, I feel like keto adaptation definitely broadened my options for how to pace myself and how to use my energy reserves during training and races.

I guess if we're sharing fitness plots, here's 1300 measurements and 7 DXA scans: http://i.imgur.com/J4Ls2bQ.png

So in the maintenance phases were you lifting, and were you pushing lifts? That's pretty scary that you can lose weight so quickly during a slack fitness period.

This matches my experience of weight loss using high fat diet. I started it after hearing Sarah Hallberg's Tedx talk. https://www.youtube.com/watch?v=da1vvigy5tQ&feature=youtu.be For a vegetarian, starting and continuing the high fat low carb diet is difficult. Are there any resources for more vegetarian recipes for high fat low carb food? The article was very impressive. I liked the graphs and presentation.

Is it? As far as I know you could sustain yourself in perfect condition (and weight) on nothing but butter & eggs (to satiation) for decades --- which most vegetarian regimens seem to allow.

I'd really like to see this kind of analysis applied to a larger sample. If someone were to put together a little app to make this sort of data collection trivial and upload it to a central (preferably cheap) repository, would people be interested in contributing their data in exchange for analysis? Also, since this is HN, is anyone interested in building something like this? I've got an hour or two a week of spare t…

We are working with a few groups to make this sort of this possible. Feel free to reach out if you are interested.

Yeah. I has been downvoted into oblivion by saying almost the same things without any machine learning, just by observing eating habits and traditions of "village folks" in Nepal, India, Tibet and Sri Lanka where I have spent last few years.

The message was that traditional (evolved according to local food sources and seasons) unprocessed foods of Asian tribes is the most natural and healthy. Economic and habitat selection pressures implicitly works the same way as machine learning, for hundreds of years.

Visit any rural area and try simple folk's foods. They will be way healthier that any processed crap. The similar patterns could be notices really quickly.

There is an often-forgot other situation where your body needs some stored energy: sickness and accidents.

I experienced this. I never needed to lose weight, always been lean. But I wanted to see if I could reduce my blood sugar since it was borderline high. So I went very low carb for a while. Did not intend to but lost 5 kilos right away and felt fine, although it seemed like I was a bit underweight. A few weeks later got a miserable case of flu and couldn't eat for a few days. Lost even more weight, felt terrible, looked like death. It seems like the little reserves I previously had were gone from my change in diet.

Breakfast: eggs + bacon or sausage or leftover steak Lunch: salad and leftover protein (with oil, vinegar, and mustard dressing) Dinner: meat, fish, or poultry (simply prepared) with roasted vegetables and salad Snacks: coffee with butter and coconut oil, raw veggies, leftover meat

I want this so badly but I feel I'm set up to fail due to how much I hate vegetables. I just can't enjoy salads. I wonder if the "this tastes awful" response will change as I move away from carbs?
