Researchers from the Eye and Vascular Institute at John Hopkins University conducted two separate studies examining the kinship between popular diets, weight loss, and eye health. Lead researcher on the discipline and exercise physiologist Kerry Stewart, Ed.D.
said that perhaps an overemphasis on low-fat diets in the United States has contributed to the obesity epidemic in the US. In a pressure release statement they explain that low-fat dieting encourages the over-consumption of low-fat foods, which run to be less filling.
However, in late years popular low-carb diets like Atkins, South Beach, and the district have likewise been criticized because, although they avoid carbs, they lean to allow a higher fat intake. High consumption of fat increases blood cholesterol which in turn causes plaque buildup in the arteries, leading to cardiovascular disease.
Therefore, when it comes down to choosing a weight-loss program, no wonder people are confused.
The first study, which will be presented at the American College of Sports Medicine in Denver, the researchers studied 46 participants who weighed on average 218 pounds. They were assigned to a 6-month exercise program plus either a low-carb diet or a low-fat diet. The low-carb dieters were allowed 30 percent of calories from pastas, breads, and fruits and 40 percent of their diet came from fats (meat, dairy, nuts, etc.). In contrast the low-fat dieters were allowed no more than 30 percent of calories from fat and 55 percent from carbs.
According to the survey results, both groups lost an average of 10 pounds, however it took the low-fat group a solid month longer to make the weight loss. Additionally, the low-carb, high-fat group showed no show of increased cardiovascular risk.
"Our study should help ease the concerns that many people who want to lose weight have about choosing a low-carb diet instead of a low-fat one, and provide re-assurance that both types of diet are good at weight release and that a low-carb approach does not appear to put any immediate danger to vascular health," says Stewart. "More people should be considering a low-carb diet as a good option," he adds.
The second study looked at the short-term cardiovascular effects of eating an exceedingly high-fat meal. The researchers examined participants blood vessels prior to eating a McDonald's meal consisting of two English McMuffins and hashbrowns as good as after. The researchers were surprised to observe that there was no quick consequence of this meal on the vascular system.
"Even consuming a high-fat meal now and so does not appear to make any immediate injury to the blood vessels," says Stewart. However, he cautions again habitual eating of these types of food.
In summary, the John Hopkins researchers conclude that for obese people look to light weight, a low-carb, high-fat diet may a good and efficient way to free weight.
"Overweight and obese people seem to actually have options when choosing a weight-loss program, including a low-carb diet, and yet if it means eating more fat," says Stewart.
