From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

This bitter information comes from a new study which found that when sugar was removed from the diet, people unconsciously tended to eat more to compensate for the calorie reduction. As a consequence dieters ate more fat, which has a higher calorie concentration than the sugar they were avoiding.
Donald Naismith, emeritus professor at the department of human nutrition and dietetics, Kings College, London Hospital, led the research. He said 10 healthy young men with no weight problems had eaten as much as they wanted from an attractive menu for 10 days. After 10 days all the sugar was replaced with sweetener, which the young men failed to notice.
"We put as much sugar as we could into the sauces and soups so we achieved a 500-calorie-a-day reduction when we removed it," Professor Naismith said.
On the sweetener menu the men ate 11 per cent more fat. "We were quite staggered by the results. In both periods of the trial, energy intake swung hugely - by 1,000 calories a day in some cases. But they were quite unaware that their intake varied."
What this proves, Professor Naismith suggests, is deeply depressing for those who find it hard to regulate their weight. Some people - lean people - he says, have bodies which are simply much more efficient in responding to what they eat.
