Hi Alipalicat, welcome to the forums 🙂 Your brother is right you should do this diet and I hope he is too!!! The fat around your middle will be the first noticeable thing to disappear.
Aldi have a large round squat tub of authentic greek yoghurt for £1.29 ( I think ) that is similar to the fage yoghurt – but cheaper. They also sell full fat cream cheese for peanuts!!!
So for protein you need full fat yoghurt, cheese, fish, eggs, beans, pulses, nuts, seeds and meat.
The fat is important on this diet – it helps to keep you full and it isn’t full of sugar and other nasty crap like the low fat yoghurts.
Aldi also sell milled flaxseed for £1.99 (£6 in sainsburys!) It is good to sprinkle a teaspoon on your yoghurt with a few berries – aids against constipation as well as being full of good stuff!!!
Aldi also sell little packets of nuts and seeds( orange colour pack) at the checkout. Useful for keeping in your handbag for emergency situations. 157 calories and 2.7g carbs.
You will find that the full fat yoghurt has carbs in it – as does milk.
If you take some general ideas from recipes in the book and this website I think your levels of protein intake will be sorted naturally. You still need your 5 a day although a lot of it will be in the form of berries and veg which grows above the ground.
You will be happy with the results you get. My niece and her husband started this diet on Monday and when they weighed themselves – fully clothed and after food – they were really surprised at how much weight they had lost by Friday!
Hope it all goes well and don’t be afraid to ask – there are lots of people on here who are willing to help 🙂
