There are many insights peppered throughout the book that help us maintain saintly behaviours, resist temptation, and plumb for the healthy option when eating out or at the supermarket.

If you’re trying to keep up a healthy diet, or can feel your willpower draining, follow some of these sensory tips

And once you’ve made your healthy choice, there are things you can do to make it taste as though you’re not missing out on any of the fun stuff.

The overall rule is; surround yourself with things that make you think of nature, freshness, purity – and those will be the first thoughts you jump to when presented with a decision.

We choose healthier food in places that are brightly lit, than in ones that are low and sultry.

Open the curtains before you make breakfast, or put the lights on full when choosing what to make for dinner.

One study in Australia showed how people bought more healthy items in a supermarket when the scent of fresh herbs was in the air.

Wear a scent that is fresh and herbal before you shop, and have pots of fresh herbs out in your kitchen to make you feel fresher.

We go for more unhealthy food in louder environments.

Keep the volume of music as low as the calories in your food.

Feeling the burden of carrying a heavy bag while trying to make a decision has been shown to lead our minds towards reward and comfort – and therefore choose unhealthy snacks over cleansing salads.

Even carrying a heavy plate makes you choose less healthy food than a lighter one. So lighten your load and lessen your burden before presented with a food choice

Smelling the aroma of some indulgent food for two minutes has been shown to reduce your cravings, meaning you can go forth and make healthy decisions.

But beware, you need to hit the two minute marker;  if you smell the smell for thirty seconds or less, you’ll just make your cravings worse.

It’s been shown that we serve ourselves smaller portions and eat less food off of red or blue plates, as opposed to white ones. It’s down to the increased contrast between plate colour and food.

Seeing as red intrinsically makes things taste sweeter, you’ll also be making your meal seem richer and more indulgent by doing so.
