has anybody noticed more weight loss if they execise than just doing the diet alone, i'd only lost 5lb in 4 weeks by having 3 shakes a day, so therfore i've been on ebay bought myself a cross trainer and an air walker at a bargain price and i just love both machines, I am doing about 12 mins on the cross trainer and it says i'm burning 100 calories done 1/2 hour on air walker (not as strenuous the cross trainer) say i burn 300 calories, also been on Amazon and ordered myself an Omron pedometer which gives distance walked calories burnt and fat burnt in grams and you can connect to yor pc and it will give you a chart read out and log eveything you do as when you were most active'
