There is more than one way to skin a cat. And that strange and grotesque cliche happens to apply to your weight loss approach. There are many diets that will get you to your goal weight, but not all of them will also have the added benefit of improving your mood.
According to a new study, only low-fat diets will help with long-term mood improvement.
“This study looked at one factor, and prior studies haven’t focused on psychological factors,” says Dr. Ewald Horvath, interim chairman of psychiatry at the University of Miami Miller School of Medicine. “This is a great study focusing on something very important.”
The key difference between low-fat diets and low-carb diets is the long-term effect on mood. Studies have previously found short-term improvements in the mood of people who chose a wide variety of different diets. This new study reaffirmed the evidence of improvements over the first eight weeks of dieting on various plans. But it’s after the initial two months that low-carb dieters tended to return to their depressed moods.
“The exact mechanism for the observed effects on mood still remains largely unknown,” says study author Grant D. Brinkworth, a research scientist with the food and nutritional sciences division of the Commonwealth Scientific and Industrial Research Organization in Adelaide, Australia.
But, it is known that carbs can increase serotonin concentrations in the brain, whereas added fat and protein can reduce it. Serotonin is a neurotransmitter that is involved with controlling mood, anger, and aggression.
