Thank you, trickydisco. Much as I’d gleaned from the various threads then.
I find the no fruit rule bizarre. Pretty much all fruits are low GI, cherries being one exception. They are also a useful source of vitamins and minerals, and satisfying to eat.
burning 2000 caloires worth of body fat a day (2kg per week) is possible with exercise in addition to the diet but any diet that leads to such rapid weight loss will soon put the body into famine mode. For many people with sedentary jobs it will mean getting over 60% of their energy from body fat assuming they burn 3000 calories a day and they get 1000 calories from their iDave intake. There’s lots of evidence that such rapid weight loss and famine mode living results in rebound when the dieters crack (survival instinct). IMo it’s better to adopt a diet you can happily live with for the rest of your life and aim for losing 100gm a week rather than 2kg simply by increasing exercise.
As previously stated, I put on a couple of kgs over winter as I find I get more colds and feel the cold more if I don’t. Those kgs go with no effort when the Summer comes and the market is overflowing with tempting strawberries, raspberries apricots, nectarines, plums and salade ingredients.
