Maybe its not the fat?
My skin also becomes a little less white when i consume loads of tomatoes (lycopene).
Do you eat a lot of carrots, apricots, muskmelons, papaya, persimmon, tree tomatoes, mango, mandarin or loquats? (containing beta-carotene)
Also, when you consume sufficient vitamin A (egg yolks, tuna, salmon)
less beta-carotene is converted into vitamin A,
and the beta-carotene levels may remain high.

I guess it makes it more colourfull.
I eat lots of mango's (like 2 a day). Kiwi's (4 a day). So that can't be the problem.
But sometimes I forget to eat oil in the morning, my skin is a little bit white (maybe also from going out, smoking marihuana and less sleep).
But once I eat some fat, a hour or half a hour after that, my skin becomes really colourfull. I like it, but I don't understand the correlation with fat.

Yes, less white.Kasper wrote:I guess it makes it more colourfull.
Im pretty sure its the latter.sometimes I forget to eat oil in the morning, my skin is a little bit white (maybe also from going out, smoking marihuana and less sleep)
Thats the blood flow, not related to the fat intake.But once I eat some fat, a hour or half a hour after that, my skin becomes really colourfull.
So carotenes cause a less white colour.RRM wrote:Yes, less white.Kasper wrote:I guess it makes it more colourfull.
I guess that this white colour is caused by the deprivation of vitamins during this activities.RRM wrote:Im pretty sure its the latter.sometimes I forget to eat oil in the morning, my skin is a little bit white (maybe also from going out, smoking marihuana and less sleep)
Why are you so sure it's because of the blood flow. Why couldn't it be caused by vitamins ?Thats the blood flow, not related to the fat intake.But once I eat some fat, a hour or half a hour after that, my skin becomes really colourfull.
I was searching about beta-carotene, and I found this article:
Since, beta-carotene is fat-soluble. I guess that fat intake can be corraleted to skin colour.http://jn.nutrition.org/cgi/content/full/132/3/399
Carotenoids also appear to contribute measurably and significantly to normal human skin color, in particular the appearance of "yellowness" as defined objectively by CR200 tristimulus b* values.
Yes.Kasper wrote: So carotenes cause a less white colour.
No, its the blood vessel constriction that restrains blood flow to the skin.Kasper wrote:I guess that this white colour is caused by the deprivation of vitamins during this activities.RRM wrote:Im pretty sure its the latter.sometimes I forget to eat oil in the morning, my skin is a little bit white (maybe also from going out, smoking marihuana and less sleep)
Hence less color)
Please explain to me how a specific vitamin does this.Why are you so sure it's because of the blood flow. Why couldn't it be caused by vitamins ?
Only if that fatty food is high in beta-carotene.Since, beta-carotene is fat-soluble. I guess that fat intake can be corraleted to skin colour.
But even then the correlation is for both fat and beta-carotene,
and only for as long as you dont eat low fat with beta-carotene or high fat without beta-carotene,
because then there is only a correlation with beta-carotene.
Also, all fruits (and vegetables) high in beta-carotene are low in fat.

Well I wass thinking of beta-carotene. I thought that maybe smoking and a lack of a sleep could make your skin white because of the deprivation of such vitamins during the night.
Well, that makes sense to me.Only if that fatty food is high in beta-carotene.Since, beta-carotene is fat-soluble. I guess that fat intake can be corraleted to skin colour.

If I eat in the morning no fat, but I eat a fruit salad with mango and kiwi's and I forget to eat coconut oil with it, my skin is white. (no fat, high beta-carotene)
If I eat later the day some coconut oil with my fruit salad, my skin becomes much more colourfull. (fat+beta-carotene)
That would explain my fat theory, because I really experienced this in the past, when I sometimes forget to eat fat.
The levels of vitamins dont fluctuate that fast; you can go many days without dietary beta-caroteneKasper wrote:I thought that maybe smoking and a lack of a sleep could make your skin white because of the deprivation of such vitamins during the night.
with only the slightest decrease in serum beta-carotene levels.
Smoking, however, has direct blood vessel constricting effects.
Hence less blood flow to the skin, hence a more pale skin.
I do believe you experienced this, but that doesnt make your theory correct.That would explain my fat theory, because I really experienced this in the past, when I sometimes forget to eat fat.
The point is that serum beta-carotene levels dont fluctuate so fast,
and that the effects of dietary beta-carotene on skin pigmentation takes a long time,
so that your skin cannot get less white within hours by consuming beta-carotene.
It takes at least a few days of very high beta-carotene intakes.
Beta Carotene, Yellow Skin and Sun Protection
My skin has become yellowish since starting Wai and I thought that something was wrong with this. In fact something is right! The excess beta carotene from all the fruit I eat has stored in my skin. Recent evidence suggests that beta carotene protects the skin from the damaging effects of the sun (sunburn, etc...). I'm not sure to what degree I would be protected in this age of depleted ozone, but it does make me think that a Caucasian could exist in a tropical, sun drenched environment without ill effect, assuming that they were Waiing. Cool, eh? 
As per wiki:
There is also evidence that common foods may have some protective ability against sunburn if taken for a period before the exposure.[27] Beta-carotene and lycopene, chemicals found in tomatoes and other fruit, have been found to increase the skin's ability to resist the effects of UV light. In a 2007 study, after about 10–12 weeks of eating tomato-derived products, a decrease in sensitivity toward UV was observed in volunteers.

I do so like green eggs and ham. Thank you, thank you. Sam I am.
