Staying fit after 40 isn't easy. In fact, losing weight gets harder once you hit your 40s because your metabolism slows down and lower oestrogen levels can cause insulin sensitivity, which can increase your cravings for unhealthy foods. The way you lost weight in your 20s and 30s just doesn't work anymore either, but dropping those stubborn kilos isn't impossible. Allow these fit female celebrities over 40 inspire you to rethink the way you move and eat.
