I need to lose about 4 stone in weight and whilst desperately wanting to do it, fail daily to avoid filling my face with crap or take adequate exercise. I know I'm really unhealthy and setting a terrible example to my DC. My ex-P died recently from a massive heart attack and it was definitely attributable to his crap lifestyle. I obviously don't want to go down the same route but despite knowing what food's good and what's not; how much exercise I should be taking - I just can't get motivated to do it. Please share any advice you may have on how you got motivated to start and then stay on track. My constant failure is really getting me down.
