简要总结
Overweight and obesity are public health concerns and there is a forecast rise in the consumption of ready meals that are generally high in saturated fat and low in fibre. Slimming World, a commercial weight management organisation has designed a range of ready meals in line with their weight management programme, which advocates an unrestricted intake of low energy dense food in order to aid in weight loss. Hence, it is valuable to understand the satiating properties of ready meals in order to establish if specific ready meals can enhance satiety and contribute to reducing subsequent energy intake. This study aims to explore the effect of ready meals on short-term satiety and food intake among females with a BMI ≥ 25 kg/m2.
详细描述
A total of 26 female participants aged between 18-65 years attended Oxford Brookes Centre for Nutrition and Health for two separate testing days. The study aimed to investigate the effects of energy matched ready meals (calorie-matched but differing quantities of protein and fat) on appetite and subsequent energy and macronutrient intake. The ready meals (Control = supermarket brand and Test = Slimming World) differed in energy density and macronutrient composition, with satiety responses investigated in the studies. The participants consumed a standard breakfast and four hours later consumed either a test ready meal (lasagne, higher energy density) or the control ready meal (lower energy density). Four hours after lunch participants food intake was measured during an ad libitum buffet tea. Additionally, satiety measurements were recorded using visual analogue scales throughout and participants completed a weighed food diary for the remainder of the test day.

结局指标
主要结局
Visual Analogue Scale measurements for Hunger
时间窗: 9 hours
Ratings were established prior to breakfast (fasted), then every 30 minutes from commencing breakfast (8 am) until lunch (12 pm). Visual Analogue Scale ratings continued every 15 minutes from commencing lunch until the buffet tea (4 pm), with the last rating being made after finishing the buffet tea. Minimum value 0 mm; maximum value 100 mm; A higher score means worse outcome.
Visual Analogue Scale measurements for Desire to Eat
时间窗: 9 hours
Ratings were established prior to breakfast (fasted), then every 30 minutes from commencing breakfast (8 am) until lunch (12 pm). Visual Analogue Scale ratings continued every 15 minutes from commencing lunch until the buffet tea (4 pm), with the last rating being made after finishing the buffet tea. Minimum value 0 mm; maximum value 100 mm; A higher score means worse outcome.
Visual Analogue Scale measurements for Fullness
时间窗: 9 hours
Ratings were established prior to breakfast (fasted), then every 30 minutes from commencing breakfast (8 am) until lunch (12 pm). Visual Analogue Scale ratings continued every 15 minutes from commencing lunch until the buffet tea (4 pm), with the last rating being made after finishing the buffet tea. Minimum value 0 mm; maximum value 100 mm; A higher score means better outcome.
Visual Analogue Scale measurements for Prospective Food Consumption
时间窗: 9 hours
Ratings were established prior to breakfast (fasted), then every 30 minutes from commencing breakfast (8 am) until lunch (12 pm). Visual Analogue Scale ratings continued every 15 minutes from commencing lunch until the buffet tea (4 pm), with the last rating being made after finishing the buffet tea. Minimum value 0 mm; maximum value 100 mm; A higher score means worse outcome.
