SOUNDS CRACKERS… BUT EATING CHEESE AND BISCUITS CAN KEEP OFF THE POUNDS

- By Professor Tim Spector

IF YOU eat more calories than you burn, you’re going to put on weight, right? Well, yes, but there are some simple diet and lifestyle tweaks that will help supercharg­e your metabolism, keep you from overeating and generally improve gut health so you’re less likely to put on weight. Here is my sixpoint plan that will give your system an overhaul… and help you keep off the pounds.

DOUBLE UP ON FIBRE

AN INTAKE in fibre can slow the absorption of food inside the gut, reducing the release of sugar in the blood after eating.

Studies also show that a diet high in fibre can increase the amount of healthy gut bacteria, which in turn can send signals to insulin receptors to regulate blood sugar. Opt for wholegrain bread, pasta, rice and oats rather than instant porridge oats and white rice. Eat plenty of fibre-rich, green vegetables such as leeks, artichokes, onions and garlic, and berries.

EAT CHEESE AND CRACKERS

COMBINING foods that are broken down and converted to energy quickly – such as processed carbohydra­tes and sugar – with foods that are broken down slowly is an effective way of reducing a blood sugar spike.

In particular, healthy fats in food combine with sugars, slowing the process of breaking down the nutrients and releasing the sugar into the bloodstrea­m. So eat cream crackers or a handful of grapes with a small slice of cheese rather than on their own.

AVOID ANTIBIOTIC­S

ANTIBIOTIC­S are like an ‘atomic bomb’ in the gut, destroying the compositio­n of the healthy, varied gut bacteria that are key in maintainin­g a healthy weight.

EAT FERMENTED FOODS

ANOTHER way to boost the healthy gut bacteria is to feed them with fermented food and drinks such as sauerkraut, kombucha and kefir – packed . with microbes. They’re not to everyone’s taste, but virtually the same effect can be achieved with natural, full-fat yogurt and fresh cheese.

SNACK ON DIFFERENT FRUITS

MY BODY converts grapes into sugar very quickly, but when I eat apples, the process is much slower. This is the case for most people; different fruits vary in the speed at which they are converted to energy. Eat a wide variety of fruits and mix berries with nuts and seeds to avoid a consistent peak in your blood sugar.

EXERCISE

STUDIES demonstrat­e that exercising shortly after eating can reduce the time taken to turn food into energy due to a decreased flow of oxygen, which, when at rest, helps to release energy from food into cells. This results in more effective regulation of blood sugar, without the peaks.
