I've certainly found that when I've done meal prep the biggest difference is that if I come home tired after work I'm much more likely to eat the healthy food I've made in bulk before, with minimal effort needed to heat it up and throw in some veg, than I would be to cook a full meal from scratch. So I end up eating better more often, and eating takeout or pizza less often.
It also saves time, as it's quicker to make a large batch that will last several meals than it is to make several meals separately.
It also saves me some mental energy in the sense that I don't have to think about what I'm going to eat and what I need to buy for it if I've already got some food waiting for me in the fridge.
For example, for breakfast – boiled eggs, pre made pancakes, fruit salad, pre made sausages (or any kind of meat of your choosing), smoothies, pre made protein shakes, pre made oats, bananas and etc.
For lunch: Pre made sandwiches, avacado (for avacado and egg toast), peanut butter and apples pre made rice, pre made chicken breat or any meat of your choosing, pre made vegetables and etc.
For dinner my mom and i usually have spaghetti because it last for a week!
Meal prep saves you time and money so I’d def try it out!
