Your plan is doable, depending on your goal. When it comes to food intake;
proteins like:
3 egg whites (not including the yellow) + sweet potate for brunch, then roasted/steamed chicken breast for dinner. Nice combination for protein and complex carbs.
add some banana and limit salt intakes.
black coffee (iced or hot) is 10 calories. Limit sugar intake, you should see results in 2-3 weeks of consistency.
protein can vary, but I would advice against getting into oily foods and rice.
tuna pasta is great too.
I did this along with water fasting. Worked out well, felt less energy on my 1st week. But then my body adapted the following days.
