Why Grumpy? Maybe it's your low-carb diet

For those who never swore dieter bread and pasta, the following sentence is not surprising. A new study in the Nov.9th issue of the Archives of Internal Medicine was published, shows that eating a diet for a year, worse after strict low-carb diets mood had a diet rich in carbohydrates (although low-fat) diet . And, yes, the number of daily calories Each group was allocated in the same way pure hunger was not the problem, and both groups lost weight.
Foul moods are surprising, the authors note, because people usually lose weight on diet, weight and feel overall mood elevator. Researchers continue that more and more Americans struggle with their weight, diets are very poor to watch in carbohydrates that are rich in protein and fat in general, still very popular. And, even though studies show that low-carb diets can be effective, long-term effects on mood and cognition are not well understood.
For the study, Australian researchers recruited 106 overweight or obese adults (average age 50) and randomly assigned half of the volunteers who eat a low carbohydrate, high fat diet for a year. The other group was put on a low fat, high carb for the same period.
Specifically, the total calories in the low carb diet are as follows: 4% carbohydrate, 61% fat and 35% protein. In comparison, for those containing the total calories in the group with a low fat content: 46% carbohydrates, 30% fat and 24% protein.
At regular intervals, the researchers tested the participants for changes in weight, mood and brain functions such as learning and memory abilities.
The good news is that a year later, the average weight loss was about £ 3o in both groups, irrespective of the transfer of power.
The bad news is that people do not profit a successful weight loss in the low-carb diet on the dynamics of mood that usually accompanies. For the first 8 weeks, both groups felt a relaxation mood. But in the course of only people held the new sunny disposition in the low-fat diet. Carb-avoiders slowly return to their levels before the weight loss bad mood.
At week 52, compared to the low-fat group, the low carb diet have gotten much higher, which is worse, in this case the tests to anger hostility, confusion, disorientation, depression and discouragement are measured. These results are consistent, the authors say, with other studies that low-carb diets link to higher levels of anxiety and depression. "Our results suggest that some aspects of the low-carb diet can deny negative effects on mood, the positive effects of weight loss have," the authors write.
Although experts do not exactly understand why the low-carb diet is so depressed, they offered a few assumptions. For starters, they highlight the difficulty of sticking to the diet in a social context where the typical Western diet is full in pasta and bread.
In addition, muse that it would be the effects of eating as much protein and fat on the brain. Both may require a negative impact on the brain serotonin, a powerful neurotransmitter for healthy brain function.
An important limitation: No Diet was on the verge of a complete fusion. Despite the significant findings between the two groups remained the general mood scores for both groups (on average) within normal limits during the study period
