"I don't make my own meals because it takes too long"
To put it bluntly, no it doesn't, you just haven't made it a priority.
If making a change in your fitness, body composition, performance is a priority to you then nutrition must have a place in there too.
Here's a few tips for you:
Protein sources- keep tins of salmon (shown here), tuna handy and cook up joints of meat, chilli's, whole chickens in bulk at the start of the week.
Veggies- buy a bag of mixed frozen veg, chuck it on top of meals to bulk them out. Or like I've done here roast a load all at the same time.
Carbohydrates- roast or boil a load of potatoes, bulk cook rice or buy ready to microwave bags in bulk.
Fats- bottles of oils, pesto, Olives, butter, nut butter all keep for ages. Keep them stocked in your house.
It takes maybe 2-3 hours max out of your week to get sorted ahead of time with food. So if you're watching TV for 1 hour+ every evening and your saying you don't have time to sort out food...time isn't the issue.
