There isn’t one, a good healthy diet includes everything you need – all your macronutrients in each meal/snack. Some people like calorie counting,, but others prefer portion control, which is hard to learn, but once you can visualise what the correct amount of food is (which will take a while so measure/weigh everything to begin with) it means you can create healthy meals and snacks.
If you’re stuck for ideas – here is a healthy eating plan based on approximately 1400 calories, but instead of exact calorie amounts, look at the weights and the variety of food suggested. I wouldn’t call this a ‘diet’, it’s healthy eating done well – all you need to do is adjust the quantities to fit your daily requirements – this calculator can help you work out yours.
