  • According to psychologists, most of the actions we carry out on a day-to-day basis are the result of automatic, unconscious processes, or habits, none more so than the act of eating.

    But the good news is, you can capitalise on these processes to replace unhealthy tendencies with healthy eating habits. It’ll take a bit of effort at first – research has found that our brains require anything from 21 to 90 days to cement a new habit – but persist and, in a few weeks’ time, you’ll find you’re eating less without even realising it. Start following these fifteen simple steps today and you’ll be well on your way to training your brain to eat less…

    Stop eating mindlessly and start eating mindfully

    Ever munched your way through a gargantuan box of popcorn at the cinema when you weren’t even hungry? Devoured your dinner in front of the telly without really tasting it? Logged onto Facebook over a cup of tea and a biscuit or thirteen?

    Well, you’re not alone. “Mindless eating is a modern-day malady,” says Rachel Bartholomew, nutrition consultant and co-author of Mindful Eating. “Our hectic lifestyles mean it’s all too easy to make mindless food choices. We reach for unhealthy snacks for a quick energy boost and we’re constantly distracted while we eat.” Eating like this not only reduces our enjoyment of the food we eat, but can lead to overeating, as we fail to pick up on the signs of physical fullness, or to register what we’ve eaten mentally.

    But, by engaging your mind, you can turn this habit around. Mindful eating is about tuning in to what your body really needs.

    “When you find yourself reaching for chocolate or some other treat, pause,” advises mindfulness teacher Anna Black. “Acknowledge what is happening without judging. Ask yourself what’s driving you to reach for it – boredom? Or is it in response to something that’s happened? Pausing and noticing your thoughts, emotions and physical sensations helps you focus. You may still eat the chocolate but it becomes a choice rather than an unconscious, automatic reaction, and sometimes bringing that moment of choice into awareness helps us break a chain of automatic behaviour.”

    Plan your meals in advance

    Planning healthy meals before doing your weekly shop helps fortify you against the powers of the junk food BOGOF displays. If you’re going out for dinner, try to look at the menu (and nutritional information, if available) online in advance. You might decide to treat yourself to a healthy starter and ‘mini’ dessert rather than a pizza substantial enough for a family of four. Alternatively, if you expect to indulge in a ‘blowout’ meal or evening out, you can simply plan an extraordinarily virtuous set of meals for the following day.

    Organise your kitchen

    You don’t necessarily need to bin all your snacks – this process is about developing a mindful, balanced approach to eating, not crash dieting. But it is a good idea to put your ‘naughtier’ treats out of sight, to prevent mindless snacking.

    Eat more protein

    Protein takes longer to digest than carbs, meaning it’ll keep you fuller for longer. Research has found that eating a high protein breakfast results in lower calorie consumption for the rest of the day. Think eggs and beans – you can leave the 7am servings of steak to the bodybuilders.

    Use smaller plates… and bowls… and spoons

    Research has found that people serve themselves a third more ice cream when given a larger bowl, and half as much again when they use a larger spoon. Using smaller plates, bowls and spoons can trick your brain into thinking you’re eating more than you actually are. And if your ice cream tends to bypass the bowl stage entirely, travelling directly from tub to mouth, start opting for individual portion-controlled pots (and yes, that also goes for crisps, popcorn, biscuits…)

    And make them blue

    Before you rush out on a mini crockery spending spree, take note. Research has found that we naturally consume less when we eat from brightly coloured plates and bowls. It’s thought that this is due to the degree of colour contrast between the food and the crockery. Try bright red or electric blue. On a side note, if you (or a significant other) struggle to eat your greens, a broccoli-coloured plate could help…

    Serve yourself 20% less

    Most people can eat 20% more or less than usual without really noticing. So, if you typically cook yourself a 100g portion of pasta, make it 80g. While you’re at it, try dishing up 20% more veg to fill you up whilst boosting your nutrient intake.

    Turn it down

    Researchers have found that not being able to hear the sound of your own chewing can result in overeating. So, if you’re listening to music or watching TV while you eat, keep the volume down. Better yet, turn it off completely.

    Eat with the wrong hand

    Eating with your non-dominant hand causes you to eat, on average, 30% less, by preventing ‘mindless’ eating. Using chopsticks (unless you happen to be particularly proficient!) may have similar benefits.

    Make it last

    “There’s a time lag of about 20 minutes between eating and the brain receiving the message that the stomach is full,” says Anna. “When we eat too quickly, we don’t create the opportunity to receive the message. If we take our time, we notice when the body says, ‘enough’.” Try setting a timer for 25 minutes – can you make it last?

    Go for a walk

    Light physical exercise after a meal helps your muscles to absorb the glucose you have just consumed and prevents insulin spikes.

    Cool off

    Brown (good) fat burns calories to keep your body warm. Activate it by drinking a glass of iced water or taking a cold shower.

    Spice it up

    A pinch of cayenne pepper can boost your metabolism by up to 25% for up to four hours after eating. Capsaicin (found in cayenne and chilli peppers) has also been found to curb hunger and reduce cravings for sweet, high-fat foods.

    Switch your snacks

    Hungry between meals? Water and chewing gum have been found to act as appetite suppressants.

    Keep a photo diary

    Develop your awareness of how much you are really eating by snapping a shot of each meal, drink and snack on your phone, and reviewing it daily.
