Does your skin colour change when you lose weight?
You asked about how the skin changes when weight is lost. It seems pretty obvious to me that the answer depends upon how much weight is lost. It also depends on what part of the body we are talking about. Here are a few situations that make this clear.Hormonal Factors and PregnancyWeight Gain is Different for Face and NeckBut your question is really about what happens when weight is lost: what does the skin do when weight is lost?Skin is Not a Single StructureStretching the SkinNeck and Facial Skin is SpecialHow the Skin Behaves Depends Upon Many Different FactorsSkin is DynamicUse It or Lose Ityes because if you lose too much weight, you become malnourished and this can change everything, from the color of your skin to the texture/thickness of your hair.
Is it possible to change eye colour naturally?
Depends on how you define natural. If shining a little stronger light into your eyes falls under that definition, then it is possible, but only in direction from darker (brown, green...) to basic blue.Why? Because we all have blue eyes. In case they are darker, they are still blue eyes, just covered with thin layer of pigment.One commercial company is starting to offer this procedure. This is so called "Strōma procedure" that disrupts this layer of pigment, causing the body to initiate a natural and gradual tissue-removal process. Once the tissue is removed, the patient’s natural blue eye is revealed. The full color change process should take 2-4 weeks following the procedure.The procedure is still not available to wide public, but they are in a phase of clinical testing.If you have brown eyes, you are better protected from the UV rays, so think about these risks before considering the procedure. I would only suggest it to treat something that really improves quality of your life, such as not being constantly stared at like in case of heterochromia, where the color of one eye differs from the color of the other eye. If find it special and beautiful, but I imagine people who have it might not agree. Luckily, we have science and hence options.Source: Stroma Medical Eye Color ChangeProcedure costs around 5000 USD.Source: WTSP video
Can medication change your eye color?
I have noticed that my eyes appear much lighter for some reason. I am currently taking biotin, niacin and a multi vitamin. My eyes seem more sensitive to light also. Could it be age related? I am 38
Eye/hair color argument.?
Sounds like your friend has been reading up on raw food diets. Supporters of raw food diets have claimed repeatedly over the past 30 years or so that all brown eyes are a symptom of toxin accumulation in the tissues, and that as a person heals, then their iris color will shift, through green, toward blue, or perhaps even an endpoint of light gray. Age-related changes in eye color occur among 10 to 15 percent of Caucasians (who have lighter eyes than other races). In these cases, eyes become lighter as a result of the progressive decrease in the number of pigment granules in the connective tissue (stroma) of the front layer of the iris. The changes were more likely to occur at the same time and with the same rate of change in identical twins than in fraternal twins, and so appeared to be genetically determined. Rarely, eye color changes can also accompany diseases of the eye, including macular degeneration, pigmentary glaucoma, and Horner's syndrome. There is no study showing a connection between diet and changes in eye color. As for hair color, most who adopt a raw foods diet do experience a lightening of the hair, but that is due to an increase in the amount of time spent outdoors, not their diet.
At what age do kittens eyes change from blue to yellow,green etc?
Depends. I've had kittens with BRILLIANTLY electric blue eyes at 2 weeks (see my avatar) who changed to green at around 6 weeks. I currently have a pair of 18 week old kittens who had marine blue eyes at 4 weeks and now have sea-green/gray-bluish eyes even still. I think they will eventually lose all the gray-blue, but not so much yet. Weird. But...to answer your question...I have rarely seen a kitten past 12 weeks of age who didn't have green/yellow/gray/gold eyes. And I've fostered 65 kittens just this past year! Of course, YMMV :) Edit: @. The kitten in my avatar has brilliantly blue eyes, yes? And no, not photo-shopped. Now that Linus is an adult he has green/gold eyes. They had already turned to green at 6- 8 weeks. And...if you could read you'd have figured out that I FOSTER cats and kittens, so I care for a lot of kittens every year, many from just a few days old. Believe me, their eyes change color. And if you think it's "creepy" that I keep track of "things like that" then you probably would find it odd that I weigh my kittens every day to make sure they are gaining weight. Kittens can "go south" VERY quickly and they can die if you don't notice a small weight loss. With foster babies I am especially careful, since they're not mine and I am responsible to the shelter to ensure that I deliver healthy, adoptable kittens. I take a LOT of pictures and try to come up with unique names designed to get the kittens noticed. Yes, I don't "get out much", but that's because both DH and I work at home (separate businesses) and we foster kittens. When we have newborns it's pretty much a 24x7 job, except that we're volunteers. You call yourself a "scientist" yet you don't know any of this? Laughable, if it weren't so pathetic..
