@femi1632 Yeah it's a game changer, I probably go above what other folks do and some may even consider it boring but her is a typical week:
Sunday I cook a dish, usually a curry. I then divide this into 4 portions so have one on Sunday evening and then it's lunch 3 days a week for when I work from home.
Dinner during the week has become me buying 4 chicken breast which the butcher cuts in to cubes. I then marinate it. I will put a small amount into the air fryer while I cut up a large salad. It can be boring but a) so much healthier and b) really keeps my weight in check.
Breakfast is just musli and yogurt.
For a single person that brings down the cost significantly, some weeks on a Saturday I will treat myself to a take out or if funds are low I will but something from M&S to put in the oven.
Some folks I have discussed this with are like how can you eat the same thing all week or don't you get bored of salad. Once you get used to it it so problem at all. I have even noticed eating salad every night has even changed the way I look at fast food, if I had it more then once in a while it actually makes me feel wretched.
