Okay. Personally I'd find it hugely more draining to be tracking and worrying about volume / mass of every bit of food I ate. 4HB - go buy / borrow a copy, and read the first fifth or so (that's the bit about diet and weight management - there may be some useful stuff regarding exercise in the latter sections for your wife, by the sounds of it). Basics are: drink more water, reduce your salt intake, cut out starch (the 'avoid anything white' rule of thumb), eat much more (seriously) food to compensate for lack of starch / carbohydrates - often up to three times the mass of what you'd be eating previously, eat (lots of!) beans - they have some carbohydrate component, but often locked up or less digestible, and they're a cheap, nutritious, environmentally-friendly versatile food, monitor your weight very carefully, don't fret about fat (but watch out for fatty foods that contain lots of salt), have a high protein breakfast early, say with 30-60m of waking, and one day a week eat however much you like of whatever you like at lunch & dinner. That last thing is what makes it a particularly palatable (ha ha) and sustainable diet for many people. To be candid I've never felt any aspect of it was especially tough - there's the social outings that may complicate things, but that's the same problem for anyone considering what they eat. Good luck. : )
