What about sex?

Well, you do burn a few calories, say, anywhere from 100 - 200 calories an hour depending on how active you are during the session, and like all exercise that gets your heart pumping there is some health benefit.

More interesting is what sex and orgasms do for your emotional well-being which is dependant upon your brain chemistry, if the sex is a positive experience (e.g. not forced) there is release of endorphins which affects cortisol levels. Simplified I believe this is how all exercise reduce stress. Cortisol levels will fluctuate throughout the day but chronically high levels are common for individuals too stressed out, that would be a real "starvation mode". The ways in which cortisol affects metabolic, but not limited to, processes in our bodies are intricate and many, it is very important to understand cortisol in regards to weight loss, overall health and emotional well-being.

Remarkable work. I am really pleased about the contribution of "sleep" in the whole weight loss experience. I have reached some similar anecdotal conclusions; I bet this is similarly not surprising for many persons.

I am not entirely sure sleep contributes only as "a fasting period". Sleep also means we are relaxed. All the other times of the day (when we are awake) we are relatively stressed, meaning more stress hormones (ie cortisol) which are known to be contributing to weight gain.

I collect some of my own data in 1/0 form in regard to whether I was productive the day before as well as a few other things (I have a google form for myself that I fill out each morning). I only have a month of data but here is what it spat out:

  FeatureName       HashVal   MinVal   MaxVal    Weight   RelScore
  ^dreams         24546     0.00     1.00   +0.0705     47.11%
  ^shower           215555     0.00     1.00   -0.0239    -15.96%
  ^exercise         190069     0.00     1.00   -0.0350    -23.41%
  ^vitamins         252959     0.00     1.00   -0.0442    -29.56%
  ^write                129676     0.00     1.00   -0.0687    -45.90%
  ^publish            12600     0.00     1.00   -0.1496   -100.00%
Which is to say that when I write and publish I also have the willpower and combined other factors to lose weight.

Interestingly I was tracking dreams because I made various changes all at once:

  -phillips hue bulbs
  -new mattress
  -new exercise routine (up from nothing)
  -started taking vitamins
  -stricter on my diet
And was wondering what the cause might be.

When I say "dreams" I mean - "did I wake up remembering vivid dreams?". I wonder now if it's related to caloric surplus.

I also have minutised step data, nightly minutised sleep data and hourly mood self-reported data that I might try to throw in to the system and see what it says.

Carbohydrates do not make you fat. I am eating a high carb vegan diet and have lost 63 pounds since last October. My weight loss: http://imgur.com/a/cGb4X 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.

Can you describe your diet and the amount of carbs in it?

This is all good if your goal is weight loss. However weight loss doesn't necessarily means higher fitness. Glycogen is fundamental if you do sports, and exercise is a major ingredient in getting fit. If I read correctly, exercise was not a big part of your experiment, how would you suggest modifying the experiment to accommodate one's exercising needs? On a side note, I reached a similar conclusion on the role of "c…

I can give a personal anecdote. About 3 years ago I began experiments with paleo, I am 5'6-5'7 started over 190lbs and in about 4 months was down to 152lbs. Weekends I would have cheat meals usually a pizza day and burger/fry day. Around then I began running for the first time in my life. I started out the first 3 months at 1 mile everyday, which I thought was a lot until a high school buddy laughed when I told him.…

One thing. Paleo has nothing to do with Ketosis. While meat and vegetables are encouraged and are the basis of the paleo food pyramid, carbs like from sweet potatos, honey, vegetables with higher amount of carbs and nuts are considered paleo.

You can argue about what is paleo and what not, but carbs are considered totaly fine as long as they come from a good source.

So if you did paleo and ended up in ketosis you probably did something wrong in regards to the paleo idea.

I kinda have to agree. But I also have to add, that it's actually the combination of fat and carbs.

As a vegan you are probably eating almost no fat and this is most likely the reason you lost weight. If you would start eating higher amounts of vegetable fats... maybe even some sugar (pure carbs) you will gain weight.

I don't doubt for many that reduction in carbs amounts to reduction in calories. For others though, eating a lot, and not worrying about consequences, is a coping mechanism for how shitty the diet is. I'm super biased from my own past experience, but I was having 3000+ calorie days with minimal exercise and losing weight on keto. Open to the idea that I'm somehow wrong though :-)

They've tried all sorts of diets in metabolic chambers - and it's really quite amazing how closely the observed results track the predicted results. Determine a person's BMR, and then feed them a variety of diets higher, or lower, than that BMR, and watch their body mass (exc. water) increase, or decrease as expected. Possibly the case that when you were eating carbs, you were putting away 3500 calories a day, and th…

The water loss is one thing I like about a low carb diet--you get positive feedback right away. It isn't real weight loss, but that doesn't matter. The point is to get started and feel like you have made progress in the right direction. Then the real, much slower, weight loss can begin.

100%. i take pills for the sodium and magnesium (they usually have potassium too but usually not enough). and avocados are a staple when it comes to potassium

I've never found potassium in sufficient quantities in pill supplements - but low-sodium salt gives you 500 mg per 5g teaspoon (and another 1000 mg of Sodium, Ironically)

Unsweetened Almond Milk is also an awesome source of both sodium and potassium - a staple for me while doing Keto.

I think your comment it accurate. As I mentioned doing paleo multiple times before I never reached ketosis. Cheat meals on the weekend aside, I also included sweet potatoe (after runs), honey and nuts (almonds, cashews).

This last time around, where I experienced the change (I believe ketosis) I can basically say my diet consisted of: eggs, chicken (mostly dark meat), red meat, green leafy vegetables, and sometimes pork. Honestly before this thread I thought of ketosis as a state, and not a diet, so I will look into it a little more and see if this last diet I was on was more consistent with ketosis than paleo.
