Brief summary
The study will measure the effect of 3 snack foods (2 types of peanuts one type of potato chips) on acute satiety and on subsequent satiety and energy intake over a 4 day period which may provide a mechanism for weight control. Hypothesis; It is hypothesised that consumption of high-oleic peanuts will improve satiety and reduce subsequent energy intake. It is anticipated that the protein and fibre content of high-oleic peanuts will increase satiety compared with consumption of low salt potato crisps of the same energy value
Interventions
Randomised controlled cross over trial with 3 treatment arms; arm 1 (~60-80g Hi Oleic peanuts), arm 2 (~60-80g regular peanuts), arm 3 (~70-90g low salt potato crisps - control) the foods will provide ~15% of participants energy intake.
Participants will consume the snack on day 1 after an overnight fast and then complete visual analogue scales (for hunger appetite, thirst, fullness and amount they could consume), at baseline and t= 30, 60 120 180 minutes. Participants will then consume a buffe

Participants will then consume a buffet meal and energy intake from this meal will be calculated. Participants will then consume the snack food daily for the following 3 days and complete food intake records. After a minimum 4 day washout period between each food, they will cross over to the other snack foods. The order if which foods are consumed will be determined using a Latin-square design
