Diving into our food cravings

With the rise of the "right food" popularity among people willing to lose weight we often meet personalities claiming they prefer having a green salad to a roasty burger. Isn't it weird?

Remember yourself, don't you crave for hot chips like crazy? Of course, you do. But don't start blaming yourself for the lack of desire to "eat healthy/clearly".

We are all humans, and it's quite naturally for us to want high-calorie food. That’s precisely your brain jonesing for a carb and fat hit.

Research published in the journal Cell Metabolism has revealed that the reward centre of the brain values foods high in both fat and carbs more than foods containing only fat or only carbs.

And the reason isn't hidden in the fact that such products taste so bloody good. We have evolved to seek out high-energy foods, and high fat and carb foods appear to “hijack” our body’s inborn signals governing food consumption, according to the study. 

According to Men's Fitness, researchers gave study subjects a limited amount of money to bid on foods and found that subjects were willing to pay more for meals that combined fat and carbs. 

What’s more, the fat-carb combo lit up neural circuits in the reward centres of their brains more than a nominated favourite food, a potentially sweeter or more energy-dense food, or a more significant portion size.

Sugar or artificial sweeteners?

Continuing our weight loss breakthroughs want to mention another study concerned our favourite drinks.

As far as we are now aware that it's our brain making us consume tons of "calories" there is a good idea to use some tricks to hack our common desire to eat sweets.

Today artificial sweeteners are ordinary things. They contain fewer calories than sugar, so it's a good substitute.

But as always, things aren’t quite so simple. According to research published in Experimental Biology, sweeteners might still promote obesity and diabetes, though through a different mechanism. 

Early studies indicate that sweeteners change the way the body metabolises fat. As always leading researchers to suggest that moderation while drinking Pepsi Max is vital.

What about some chilli?

Trying to lose weight? Chilli peppers can actually work wonders for your digestive system. Thus it will cause metabolism improvements.

New research, published in the Proceedings of the National Academy of Sciences journal, suggests that eating more foods containing capsaicin (the compound responsible for giving chillies and other spicy foods their kick) can help improve gut health by activating a type of immune cell that suppresses inflammation in the digestive system.

But be aware the health of your gut has a huge impact also on your mental health and wellbeing, not only on how easily you gain or lose weight.

How music impacts our appetite?

Having understood the latest food hacks, science gave us let's find out what actually to listen while having lunch.

A study from the Uni of South Florida, US, has found that the louder the music is in the restaurant, the more unhealthy food customers will order. 

Researchers held a study at a café in Stockholm, Sweden, where different genres of music were played at 55 decibels and 70 decibels at various times over several days. 

When the music was louder, researchers found 20 percent more customers ordered something that wasn’t “good” for them, compared to those who dined during the lower volume times. Loud music cranks up your heart rate and arousal, making you more reckless.
