A PROFESSOR has shared his years of research into what foods really keep off the kilos, and the results may surprise you. Eating unripe bananas, avoiding mashed potatoes, skipping the tofu and avoiding sweet smoothies can all help dieters maintain a healthy weight, say biochemistry Professor Rodney Bilton of Liverpool John Moores University, in his new book Know What to Eat, co-written with Dr Laurence Booth. They share their findings on their website knowwhattoeat.com.

Eat green bananas

Dieters should eat green, unripe bananas, which are high in resistant starch, which doesn’t cause blood-sugar to spike, meaning it doesn’t trigger hunger. It also encourages he release of hormone glucagon, which makes us burn fat faster.

Skip the mashed potatoes

Avoiding sugar is key to losing weight, they write. And 25 per cent more sugar is released from a potato when it is boiled and mashed, compared to cutting it into chips. The way we prepare food or even how much we have to chew them, can have a huge effect on the sugar released into the blood. Heating and mashing starches turns them into sugar.

Drink more water

Drinking water can help reduce back pain and keep the weight off by reducing dehydration.

Go easy on tofu

Tofu is made from soy beans that contain phytic acid, which can block the absorption of essential minerals. Vegetarians who rely on tofu as a meat substitute should follow the Japanese’s example and east it with miso, which contains bacteria that lowers the acid.

Don’t be afraid to eat fat

Too many of us have shunned high fat foods in favour of refined carbs like rice, pasta and bread, which don’t leave people feeling sated. Instead, meals that are high fat promote hormone glucagon, which promotes the breakdown of fat.

Skip sugary smoothies

Sugary drinks and treats like fruit juices and smoothies contain high levels of fructose, the sugar found in high-fructose corn syrup. Unlike other sugars, fructose slips past our insulin system, which normally controls sugar getting into the bloodstream and control appetite. That means fat builds up in the liver, causing obesity and diabetes.

They also write that controlling your hunger is far more useful to dropping kilos than counting calories. They recommend eating foods high in protein and fat, which are digested more slowly and keep us feeling fuller for longer.
