Learn How The Four Body Types Determines A Celebrity Body Type Like Hilary Duff
Celebrity Hilary Duff shows off her genetic scientific Standard Body Type One (BT1) shape figure/physique while on vacation with family and friends including her husband Matthew Koma. The 
full development of her vertebra (posture) and muscles/muscle mass is currently not in debate. The 
candid images reveal no obvious skinny fat (cellulite, thin fat, loose skin, saggy skin, crepey skin, normal weight 
obesity) anywhere on her body. However, there are possible hints of thin fat or/and cellulite skinny fat on her buttocks, upper legs, and lower back
Science recognizes that one pound of muscle burns six calories daily, but one pound of regular fat (white fat/yellow fat/excess fat) and/or skinny fat only burns two to three calories. Which directly affects metabolism (the more skinny fat and/or regular fat, the slower the metabolism) as well as body composition and shape. Having so many developed vertebrae, muscles, and muscle mass assists greatly in terms of metabolism/ metabolic rate (BMR), including aging gracefully.
Diet, exercise, lifestyle, metabolic rate (BMR), and BMI matter. But so do genes/genetics/DNA. As she continues to age, it will be interesting to see how well Hilary Duff maintains her body shape figure/physique as her metabolism slows. Is she really a Body Type Two (BT2) with a slightly underdeveloped sacrum vertebra and maybe a lumbar vertebra(e) or several?
Hilary Duff Figure/Shape – BT1
Star singer and Hollywood actress Hilary Duff displays her Body Type One shape/figure during her time off. Encouraged by her parents to take acting, singing, and ballet classes at a young age, 
roles in local theater productions including touring with the BalletMet production of The Nutcracker in San Antonio, Texas, led to a move to California in 
1993 to pursue acting opportunities. Several years of being cast in 
diverse television commercials and modeling for various clothing brands led to an initial minor uncredited television acting role in True Women (1997, CBS).

Paying her dues, a supporting role in the 1999 television film The Soul Collector (1999) was followed by an appearance on an episode of Chicago Hope (2000, CBS). Finally breaking through, in 2001 she accepted the lead role in the Disney Channel TV comedy Lizzie McGuire which catapulted her to fame and teen idol status.
She made her debut as a singer on the Lizzie McGuire soundtrack covering the Brooke McClymont song I Can’t Wait. Expanding her horizons, she recorded a Christmas-themed Santa Claus Lane album in 2002, with the single Santa Claus Lane charting on the US Billboard 200. The album earned gold certification from the Recording Industry Association of America (RIAA).
