Is Madonna's macrobiotic diet and ultra-intense fitness regimen ultimately healthy? Her hands these days are a roadmap of veins. There's sinewy and Madonna-sinewy -- check out these pictures -- do you think she looks like the picture of health?

Five UK experts share their observations and advice from afar:

• Cheeks: Her protruding cheekbones are due to a lack of fat and ageing -- fat departs the face as we age.
• Body: A muscular size zero is not the rage -- fit and healthy is in. Also, hormonal balance requires rest.
• Hands: Loss of oestrogen due to menopause may cause collagen to thin. Also, as we age, veins don't return to normal size after exercise.
• Hair: A deep-moisturizing treatment is in order, and the roots-showing-through-look is not age-appropriate.
• Diet: Her macrobiotic diet is healthy, but possibly too acidic. A few more raw vegetables and fresh fruit may be in order to produce fresh blood cells and prevent loss of too much muscle and body fat.
