SMELLS TO HELP YOU LOSE WEIGHT


People have used the scents of plants, trees, herbs and fruits since ancient times to fight inflammation, depression and induce sleep. “Smells act on the brain like a drug,” says neurologist Dr Alan Hirsch, founder of the Smell and Taste Treatment and Research Foundation in Chicago.
“In the future there will be new treatments based on smell.”

Smells stimulate nerves in the nose that send impulses to the brain. These impulses usually go to the brain’s limbic system which is the center of our emotions, and this may help to explain why so many scents can trigger our emotions and memories. The limbic lobe in turn directly activates the hypothalamus, which houses and controls our satiety center. In other words, our nose dictates our hunger level more quickly and more efficiently than our stomach!

Appetite suppressing scents whose effectiveness has been proven
In scientific research, people preferred sweet smells, and strongly sweet scents such as chocolate often triggered feelings of hunger and led to overeating or binge eating, while “neutral” sweet smells actually curbed appetite.

Green apple and banana
To test this theory, researchers asked 3,193 overweight people (mostly women) aged 18-64 to inhale a variety of “neutral” sweet smells, including banana, green apple, vanilla, and peppermint, three times in each nostril whenever they were hungry. After six months, the participants in this study lost an average of five pounds a month, or 30 pounds in total.

Vanilla
Researchers have found that the scent of vanilla specifically reduces your cravings for chocolate and it can also reduce your cravings for other sweets. You can spray vanilla-scented perfume, use a vanilla-based air freshener or light a vanilla-scented candle when you feel tempted to reach out for something sweet.

Peppermint
Bryan Raudenbush, a professor at Wheeling Jesuit University in West Virginia, found that volunteers who sniffed peppermint scent every two hours were not as hungry as nonsniffers and — even better — they ate 2,800 fewer calories in a week. That's enough to lose close to a pound.
The peppermint, he says,  “is distracting you from your hunger pains, and you don't feel as inclined to eat as much.” Raudenbush's earlier studies showed that athletes perform better if they sniff peppermint. “They were able to go longer at the gym, able to push themselves, were more motivated, less fatigued and felt like they had more energy.” The study also concluded “another implication would be that peppermint scent could be used to curb individuals' false hunger cravings, i.e. emotional eating.”

Garlic and spicy foods
According to a 2012 study in the journal Flavour, strong aromas make you take smaller bites of food. Look for spicy food with bold flavors like chiles or onions, or try sprinkling red chile pepper flakes into a simple soup for a strong kick.

Extra Virgin olive oil
A new study from the German Research Center for Food Chemistry found that even just smelling Extra Virgin olive oil may lead to greater feelings of fullness. When an aromatic extract was added to yogurt, participants consumed fewer calories and had a better blood sugar response compared to those who were given plain yogurt without any added extracts. They also had higher increases in serotonin, a hormone associated with satiety. This is great news for olive oil enthusiasts because this potent substance is also loaded with MUFAs, the healthy fats that help blast belly fat.

Grapefruit
This vitamin C and lycopene-loaded citrus powerhouse is a favorite fruit of dieters, but it might boost your weight loss efforts even more if you take a few seconds to smell it before digging in. Researchers at Osaka University in Japan found that exposing rats to the scent of grapefruit oil for 15-minute intervals helped lower their appetite and weight. Researchers believe it may have to do with how the smell interacts with liver enzymes.

Fennel
This crunchy, refreshing plant with a hint of licorice flavoring has long been used by Italians as a palate cleansers between courses, but according to the West Coast Institute of Aromatherapy, it also functions as an appetite suppresant. When cravings hit, break off a stalk or two of the celery-like herb and have a tall, cold glass of water.

What's lurking in YOUR salad? Experts warn prewashed spinach still contains 90% of its bacteria and can cause food poisoning

Health experts have warned against eating pre-washed spinach. They say commercial washing techniques fails to remove 90% of the bacteria. Small peaks and valleys in baby spinach leaves could be a key reason why there have been numerous bacterial outbreaks involving leafy green vegetables, they say. Greens are washed by commercial processes before they head to the grocery store.  But these methods, which can include water and bleach rinses or irradiation, are not completely effective, says Nichola Kinsinger of the University of California. She says scientists have estimated that 99 percent of food-borne illnesses from leafy greens can be traced back to disinfection issues.  'In a sense the leaf is protecting the bacteria and allowing it to spread,' said Nichola Kinsinger, a post-doctoral researcher working with Sharon Walker, a professor of chemical and environmental engineering.  'It was surprising to discover how the leaf surface formed micro-environments t...

Sweet News: Dark Chocolate May Prevent Obesity And Diabetes

If you’re going to munch on chocolate, choose dark chocolate. It’s something that has gained popularity as growing research points out the various health benefits of eating dark chocolate in moderation. Antioxidants and flavonoids make it so good Studies have shown that dark chocolate, which is rich in flavanols — a type of healthy antioxidant — can improve your cardiovascular system. Chocolate is also filled with other types of antioxidants and flavonoids , the latter of which are found in various fruits and vegetables. Flavanols are the main type of flavonoid in cocoa, and have been shown to improve vascular health by lowering blood pressure, improving blood flow to the brain and heart, as well as boosting the clotting properties of blood platelets. Not all chocolate is created equal In fact, that strong bitter taste in really dark chocolate comes from flavanols. That’s why processed chocolate — which goes through plenty of steps to reduce that bitter taste — is sweete...

SOUPS THAT CAN HELP WEIGHT LOSS IMPROVING SATIETY & BOOSTING METABOLISM

Soup is often listed as one of the foods it’s a good idea to add to your diet if you want to lose weight. But with so many different varieties to choose from, ranging from thin consommés to rich, creamy soups – not to mention myriad slimming soups from cabbage to crazy – many of us are left wondering what the best soup for weight loss is. Soup and weight loss: the scientific evidence Increasingly, research has revealed that consuming soup improves satiety (the feeling of fullness at the end of a meal) so that we eat less and take in fewer calories which is great for weight loss. Eating soup appears to be far more effective – and a whole lot tastier – than drinking a glass of water with a meal to help fill us up, the latter of which is often a top diet tip. In a study from Pennsylvania State University, researchers asked women to eat chicken casserole, chicken casserole with a glass of water, or chicken casserole with the same amount of water added to make a sou...
