In reality, there aren't many 'rules' to a good fat loss centric day of eating. People have this massive list of 'important diet things', which only makes 'eating well' and achieving weight loss, seem out of reach and unattainable. Perceptions that 'eating veg with every meal', 'eating 6 times a day', and 'cold chicken & veg for lunch', matter are all incorrect concepts. It's these sorts of things that don't matter and only make your life harder for no benefit. All you really need to worry about is Calories, protein, and plants which all tie into one another once practically applied.
The above is an example of what would be perfectly fine and appropriate for the individual whos working hours are an absolute mess of work and stress where 'eating & food' is a low priority. It's not going to work for everyone who has busy jobs/days, but I've found that taking 'food thought' away at appropriate times over the day as a useful strategy for my busier, clients. (think corporates)
Breakfast
The protein and plants focus is achieved through the non-fat yogurt and fruit. A small-ish amount of whole grains and healthy fats are added as extras.
Lunch
Too busy to think about eating, but want to crush that drive towards the work office cookie jar? Protein bars are a perfectly okay protein dense food in the context of an overall healthy diet that can sit in your desk drawer, and satisfy those peckish snack food workplace cravings. Bulk the meal up with some filling plants (fruit) that you picked up on the way to work, to fill out your daily fruit requirements.
Dinner
You're back at home, a little more relaxed and keen for a big bowl of food volume. Start with a lean protein and a whole days work of vegetable needs via mixed ingredients. Top it off with a little carb via some high fibre grains, potato or beans. Enhance it with herbs, spices, low-Calorie sauces or passata.
