We are so often reminded about the need to watch our weight but it is surprising that just one portion too much each day can pile on more than a stone in weight each year – and every year! If we can’t get it off during the summer, most people find the winter a more difficult time because we can hide our fat tummy under a big cardigan during the long, dark nights. Weight gain is exponential: the more weight we have, the less active our life, so the more weight we gain. This puts a strain on joints, increases our risk of fatty liver, heart disease and strokes, and is now said to increase our dementia risk also.
