Or not getting out with their camera enough, and not walking their dog if they have one. I eat far too much, and all the wrong things. I can have a big breakfast, large lunch massive evening meal and supper. Oh and sweets etc, not forgetting generous helpings of cake. Friends and family always comment on the amount I eat, I am 5ft 8 in and weigh 12 stone 8lb sorry to our young members, don't know what that is in new money. I have eaten like that for as long as I can remember, and my weight has been the same since being an adult. I have always had dogs, and take the dog for three brisk walks a day, even if it's raining.
If I was not mobile for some reason and I could not exercise, I would definitely cut down and eat more healthy. So being physically fit, I will continue to eat like a pig
