@Milly21 - I am not a dietician but I did train as a Home Economist ...... and worked in a major Sydney Hospital, helping in arranging diets for patients with special needs, e.g. Diabetics, Low Cholesterol, weight loss etc.
As the girls above have mentioned - everything in moderation - nothing to excess. Limiting the number of times you eat 'shop prepared food' (like frozen foods, e.g. lasagnes, pies etc) and trying to cook your own meals (even cooking double sized and freezing some or later!!) is a good thing. If you are worried about Carbohydrates, cut out the Gravy or just have 1/2 potato instead of a whole one ..... A good mix of everything is great - cutting out one whole type of food like Carbohydrates is more of a 'fad diet' - as the body needs Carbohydrates for energy. NOT eating CHOs could lead to weight loss. If this is what you are aiming for - well & good (for a short period of time) but not to be done 'long term'! If not provided with the required CHOs for energy (from the diet) - the body may start breaking down it's own flesh to try & get the nutrients it needs! This will lead to weight loss.
Pretty well everything you eat will eventually break down into 'simple sugars'! So cutting out Carbs (4cal/gm) won't necessarily work anyway - as even 'fats' eventually break down to 'simple sugars' (9cal/gram)!
Snacking on nuts between meals can be good - a handful of Pistachios and/or cashews now & then - but needs real discipline, as they are so tasty! ;) ...... and keep your exercise levels up to keep the body supple and lean .....
All the best with your recovery. xx
