Going food shopping is an assault on the senses - the bread smells unreal; the crisps and beer are on offer; and you need the chocolate just in case...
Before you know it you've come out with a tonne of sh*t you didn't need or want.
A good strategy is to have a list - plan ahead and roughly know what you want to cook/eat the following week.
Getting your food right is such a big part of achieving most fitness goals. Calories too low (YES! - It's a big problem!) or too high and you won't see results. If you're going to keep going with a healthy eating lifestyle - then you need to feel full and satisfied by your food choices.
Does that mean no treats? - No not at all, you make them fit into your weekly food plan - I use My Fitness Pal to track my macros and fit in treats this way.
So for anyone interested, here's my usual shopping list:
Sweet potatoes, white potatoes, rice, avocado, onion, peppers, rocket, spinach, mushrooms, porridge oats, cheese, Greek yogurt, chicken fillets, lean mince beef, apples, turkey rashers, garlic, ginger, oranges, milk, almond milk, eggs, turkey, frozen berries, almonds, cashews, berries, peanut butter, snickers ice-cream, dark chocolate, rice cake, coconut milk, tomato puree, herbs, spices.
Hope that helps - as always get in touch with any Qs.
