Thats true. But i cant go over the cost of what its replacing which is say bacon/eggs or tuna. I'll have a think. Dont have a blender either :/ Might get one for xmas lol
Whey and oats will almost definitely work out cheaper than any whole food, cal for cal. Also you don't need a blender if you buy ground oats, I used to shake them up with whey in a shaker and it was absolutely fine. You'll be lacking in vitamins and minerals which you'll need to source from elsewhere, though. Here's my diet when I'm keeping things cheap:
Meal 1
50g pea protein powder (40g protein), 2 scoops of psyllium husks, 1/2 a scoop of vitamin B5
Ham and cheese sandwich (Burgen Bread)
5 fish oil soft gels
1 Multivitamin
Snack
Peanut butter (100g) sandwich (Burgen Bread)
Meal 2
50g Pea protein powder (40g protein), 2 scoops of psyllium husks, 1/2 a scoop of vitamin B5
2 Frozen chicken breasts wrapped in bacon
4 Sausages
2-3 Eggs
5 Fish oil soft gels
1 Vitamin B5 Super Complex
I haven't calculated the macros precisely, but should be around 200g protein, 50-60g carbs, maybe 80-90g of fats.
