Re the treadmill.

A lot of recent work shows that exercise has much less effect on weight reduction than "people" think. You need to compare the calorie burn rate against normal day time (not 24 hour average as sleeping metabolic rates are much lower than waking rates) and also understand that research also shows that metabolic rates sink lower than normal daytime rates for several hours after exercise has stopped particularly whilst people rest and recover. It is a normal reaction to the higher burn during exercise. Hence the conclusion that whilst exercise is obviously beneficial for other reasons it doesn't really help with weight loss.

The only answer is I'm afraid calorie intake reduction and that means alcohol and portion control and drinking diet drinks.
