Did you know it's healthy weight week (15-21 February)? - an initiative of the Dietician's Association of Australia (DAA). Have a look at the website (http://healthyweightweek.com.au) for some helpful tips and resources you could use.
With my wholefood perspective, I would happily endorse a similar rotational meal plan i.e. shifting between red meat, fish, vegetarian, chicken main meals on consecutive days, and we eat ourselves this way. BUT here're some food swaps I would recommend (again how we eat):
whole grains like oats, quinoa, rice in instead of commercial cereals
no need for bread at almost every meal
a quality (and delicious!) sourdough instead of commercial bread products
can have salads without sandwiches or wraps, but with a simple, homemade salad dressing
more variety of vegetables instead of filling up on bread
smaller serves of full-fat natural yoghurt (Yalna's biodynamic or a Greek yoghurt) instead of low-fat flavoured tubs;
full-fat, organic, non-homogonised milk - and not too much of it
fresh seasonal fruit, instead of tinned fruit
avoiding commercial low-fat icecream - homemade with natural ingredients is really quite easy and free of all the awful additives in many commercial icecreams. (Our go-to dessert is baked fruit crumble with a homemade custard).
Commercial breads and bread products, wraps in particular, cheese and processed meats are very high in salt. The combination of muesli or cereal flakes, low fat yoghurt and tinned fruit could easily provide 9 or more teaspoons worth of sugar. And that's for breakfast! These are not what a body needs to be healthy.
Most people ARE very confused about what a healthy diet is. A good place to start is just to make simple changes and choose simple, easy to prepare fresh foods: neither costly or complicated. Contact me if you need some advice or practical help.
