Hi Viola
On the BSD, you have to get used to reading the nutrition panels on foods, so that you get to know which are full of sugar and/or high in carbs and so are best avoided. Of the list you gave, I would say the items to avoid completely are: Salad Cream, Noodles and Pasta regardless of whether or not they are wholewheat (any thing with wheat is a no-no as these are high in simple carbs), similarly maize is high in carbs, but a little sweetcorn in a meal is a okay and finally Branston pickle has a high sugar content, so again should be avoided.
Things like nuts, seeds, beans, chickpeas, lentils etc. contain complex carbs, but should be consumed in small portions if you are aiming to keep carbs as a low component in the makeup of your 800 calories. Things like onions and tomatoes are higher in carbs than you might suspect, so again, consume in small amounts to keep your carb intake low.
Really, there is some trial and error involved in the early days of doing the BSD and I would recommend that you record everything consumed – both calories and grams of carbs – so that you can track what makes up your diet and can see where adjustments might need to happen.
Sorry if this all seems complicated, but once you get your head around it, it’s actually much easier than it appears at first glance. Basics are, eat full fat and include things like olive oil, nuts etc – these make you feel full and stay that way for longer; drink plenty to keep yourself well hydrated; avoid simple carbs especially wheat, potatoes, cakes, breads, biscuits, pastas, rice (brown and white) and anything high in sugars; weigh and measure what you are having whenever this is possible (at least in the early days) and finally record what you consume and track your progress too.
Hope the above is in someway helpful. I’m guessing although you say you are not a diet person, you are looking to make some healthy choices and maybe lose a bit of weight along the way and the BSD is an excellent way to go. ….. Good Luck!
