We eat the same diet, except that Mr B sometimes has toast at breakfast and will have larger carb portions than me, when I have carbs. When I'm not around, his diet will have a few more carbs in it, but not outrageously so. He commented once a few weeks ago, almost annoyed, that he couldn't be bothered with most of the carbs, when he's cooking for one.
When we emabraked on a lower carb way of eating, he also trimmed up, and he's now sitting at 67kg on his 5' 7" body. He's very trim, in a 32 inch waist, but still has plenty muscle around and very good skin tone.
@donnellysdogs - perhaps your husband revert to a pizza because it was, easy, convenient and "makes a change" without "worrying" about an alternative for you? Just a thought.
