Brief Summary

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.

Outcome Measures

Primary Outcomes (6)

• Visual Analogue Scale measurements for Hunger

  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.

  9 hours

• Visual Analogue Scale measurements for Fullness

  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.

  9 hours

• Visual Analogue Scale measurements for Desire to Eat

  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.

  9 hours

• Visual Analogue Scale measurements for Prospective Food Consumption

  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.

  9 hours

• Energy intake after ad libitum buffet tea

  Total energy consumed at the ad libitum tea given 4 hours after the control/test ready meal

  4 hours

• Macronutrient intake after ad libitum buffet tea

  Total macronutrient amounts consumed at the ad libitum tea given 4 hours after the control/test ready meal

  4 hours
