I'm three weeks paleo as of today and seeing lots of improvements like fitting into a too tight skirt and not wheezing on an awful humid day like today. I even think my hair is getting thicker! But the weirdest thing is my lips look fuller and are more red. I noticed it but then my husband commented too. I thought that this might be one of the reasons people look younger in their "after" shots? Maybe good fats plump the skin including lips?
(If this is a real thing due to paleo someone should alert Hollywood so that people would quit destroying their faces with implants!)
I'm 3 months in and I'm having the same experience as you. I've actually mistakenly thought that I had already put on my minimal make-up several times recently (when I had not!) It's not just my lips, it's my whole face and the difference is fairly dramatic. My lashes & brows are slightly darker, my skin is clearing and taking on a creamy glow, and my lips are a deeper pink. A completely unexpected and VERY welcome side effect!
Probably the best benefit of eating lots of good quality fats is the glow and anti-aging! I definitely look younger now than I did when I was vegan 2 years ago! While vegan I suffered from horrible, flaking dry skin, eczema, rashes, cracking lips and a 30 pound weight gain in just one year.
I don't know about actually getting plumper, but I used to have very light lips, which I hear is a sign of adrenal fatigue. Since quitting the SAD, my lips are much redder and seem to be better defined. I've wondered if they're actually bigger, but I generally just write it off as simply being more noticeable.
My nieces told me after I lost about 25 lbs, that I looked 10 years younger. Recently, after about 35 lbs loss and a very slim body, they told me I was at least 15 years younger and asked me where my butt went!! (it usually arrived in the room before I did).
So I don't know about fuller lips or better hair, I'll happily take the 15 years younger!!
Sometimes when I've lost weight people react like I'm sick and get all 'worried', not this time!!!
