Richard Doughty was 170 cm and 66 kg when diagnosed giving him a bm of 22.8. He then went down to 60 kg on his own accord giving him a bmi of 20.7. He then went on the newcastle diet, eating about 600 to 800 calories a day of nutrition shakes and vegetables, drinking loads of water. On day 11 he weighed 56 giving him a bmi of 19.38. He then stopped, and took a fasting glucose test some months later and he was officialy declared cured.
He then changed his diet, and started to exercise reguarly, care to not put back again those 10 kg.
Here is his diet now.
…and the 1,750-calorie diet he follows now
Breakfast Home-made muesli – uncooked porridge oats mixed with sultanas, blueberries, plums or other berries. Plus almonds and skimmed milk. Toasted rye bread with thin layers of Benecol spread and jam. Occasional scrambled eggs over a giant grilled tomato.
Lunch Main meal of the day – from a choice of chicken, tinned tuna, fresh oily fish, steamed non-starchy vegetables cooked al dente, just 50g of brown rice or wholegrain spelt/spinach pasta. Or go Greek with olives, hummus, feta cheese and salad. Fresh fruit (berries, apples, oranges, etc, with fat-free yoghurt), creme fraiche, quark.
Supper Thick, home-made soup such as carrot and coriander or mushroom. Or Greek or chicken salad, followed by fresh fruit.
Plus Several glasses of fresh/flavoured water or herbal/fruit tea daily, plus ordinary tea, decaf coffee.
I will now mention the things he eats that many people claim people who are cured of diabetes cannot eat.
See that he eats muesli, rye bread with margarine, jam, and porridge oats for breakfast. He drinks skimmed milk and has some fruit as well.
Lunch is fat free yoghurt, and fruits.
Supper is a soup of carrot or mushrooms with fruit as dessert.
So this guy eats a amount of carbs many here will not advise, especially since he is "cured", and he still keeps his sugars. Read and be inspired.
