Eat it:
Protein sources such as meat, eggs, fish, tofu, nuts
Veg- 'above ground' veg
Fruit- apples, pears, berries - try and eat as part of meals only
Dairy- cheese, milk, cream, cottage cheese, full fat Greek yoghurt
Fibre- increase your fibre intake to approx 14g per 1000 cals of food.
Beat it:
Sugar. Natural sugar (honey, molasses, dates, fruit syrups) included.
Potatoes (sweet and all white varieties)
Bread, and most flours (some flours made of chickpeas, almonds, coconuts etc are ok) - and all foods containing flour such as bread, and pasta,
Rice
Cereals , except a very occasional portion of steel cut porridge if necessary
Alcohol- consume in moderation. It will impede your insulin regulation and slow down your progress, but a small drink occasionally of red wine or spirit won't be the end of the world!
Track it
use a calorie tracker to keep on top of your intake.
You can aim to keep carb grams under 50 per day as a guide, but not compulsory
We aim to eat 800 calories per day, but some have found 1000 more manageable, and achieve similar weight loss if carbs are kept low.
