What is the difference between a successful diet and a failure?The results of the research approaching the answer have been reported.Those who failed to diet have been revealed that they have a strong hungry and appetite, despite the small amount of energy intake amounts of energy intake.The result of the substadies of "PREVIEW" research held by eight countries.
Intervention research aiming for 800kcal meals for 2 months and reducing weight by 8 %
It is known that the effect of eating and exercising for obese people is quite varied.In cases where intervention does not work, it is probably due to the lack of compliance, but there is no other factor at all.However, it has not been clearly revealed what their factors are.
The study of the papers introduced this time is a substady of "Preview" research, which is evaluated in multifaceted international joint research, which interactions with dietary therapy and physical activities for obese and physical activities due to physical activity. It was implemented.
PREVIEW participated in the Eight countries: Britain, Denmark, Finland, the Netherlands, Spain, Bulgaria, Australia and New Zealand.Preview was a 36 -month long -term intervention in total, but the first eight weeks were the weight loss phase, and then the maintenance phase, and the weight loss phase aimed at reducing the base line weight of 8 %.
Meal -presence is used for dining with weight loss phase, the amount of energy is 800 kcal, and the composition of major nutrients is 15 to 20 % lipids, 35 to 40 % protein, and 45-50 % carbohydrates.In addition, we all allowed energy -free beverages and low -carbon vegetables such as lettuce, celery, broccoli, and cucumber.
Participants' compliance was confirmed in the second, fourth, sixth, and eighth week.Evaluate weight, physical composition, blood pressure, and heart rate before and after the intervention of eight weeks.In addition, he evaluated physical activity implementation status, hunger, appetite, eating behavior, sleep, and QOL.Of these, a 100mm visual analog scale is used for evaluating hunger and appetite, and sleep is the "Pittsburgh Sleep Quality Index; PSQI)", and QOL is a simple version of WHOQOL-100 by World Health Organization.WHOQOL-BREF "was evaluated.
What is the difference between the base line data between the weight loss achievement group and the non -achievement group?
It was 10.2 % for women and 7.9 % for men who could not achieve 8 % loss during the weight loss period.The weight loss of the group was reduced by 10.9 ± 2.0 % for women, 12.4 ± 2.7 % for men, 4.7 ± 2.4 % for women and 4.8 ± 2.3 % for men.The weight loss was more than twice as much as the achievement group and the non -achievement group.
Comparing the base line data of the achievement of weight loss and the non -achievement group, the age of the non -achievement group was significantly younger (49.8 ± 12.4 vs 51.7 ± 11.2 years old).The age of men was not significant in both groups.The weight of the baseline is 94.7 ± 18.3 kg for women, 96.4 ± 22.4 kg in non -achievement groups, and 109.5 ± 21.2 kg, 112.5 ± 26.1 kg in the same order, and both men and women are weighted.However, the difference from the achievement group was not significant.
In addition, the baseline data with significant differences is as follows.
Heart rate and awareness stress during rest were higher in the non -achievement group.Regarding eating behavior, dietary restriction scores were higher in the non -achievement groups, and the score of detachment was higher in the achievement group.The feeling of fullness evaluated by VAS was lower in the non -achievement group.In addition, the feeling of fullness evaluated by VAS was positive correlation with the weight change rate (weight loss rate).
Men have a greater difference between an achievement of weight loss and non -achievements than women
When comparing the changes caused by the eight -week weight loss phase between the weight loss group and the non -achievement group, a significant difference in the amount of fat, fat loss, body fat percentage, and waist size change was recognized.In addition, the amount of changes was recognized by a significant interaction by gender, and the difference between the achievement group and the non -achievement group was more noticeable than women.
If the weight loss phase was 56 days, the daily energy deposit was -1,299 kcal/day in women's achievements, while the non -achievement group was calculated as -656 kcal/day.For men, it was -1,659kcal/day, and -815kcal/day in the same order.
In the non -achievement group, the feeling of fullness is greatly reduced and the quality of sleep is not good
The fact that the non -weight loss achievements cannot maintain the energy payments negatively every day in the weight loss phase are recognized for their appetite and sleep -related indicators, and the difference in fullness, quality of sleep, and sweetness.Was noticeable.
For example, the feeling of fullness was a decrease of a woman achievement of -2.80 ± 29.8, whereas the non -achievement group dropped significantly to -14.9 ± 30.2.The achievement group -16.7 ± 30.7 for the achievement group -6.80 ± 27.7, and the gap between men and women was p = 0.0006.The comprehensive score of the Pittsburg sleep questionnaire (indicating that the higher the quality of sleep, the higher the quality of sleep) is a group of women -1.12 ± 2.78, non -achievement group -0.91 ± 3.19, male achievement group -1.09 ± 2.63Achievement group -0.19 ± 2.13, and the gap between men and women was P = 0.0501.
In conclusion, about 10 % of the participants of this research were recognized for their actions that hindered weight loss.The authors have stated that the vulnerability could be emphasized by long -term dietary restrictions.
