Recruiting Trial

The GI of porridge supposedly allows its' energy to be released relatively slowly, but can leave you hungry. Fruit, being higher in GI should be more 'satisfying' soon after you eat it. So, by eating, say, 30g of porridge (~110 cal) with a banana (~90cal), or 50g of porridge (~200 cal) you might go longer without feeling hungry. A daily routine that doesn't involve varying amounts of physical labour would help control the two trial groups (demand on the food you've eaten) and portions depend on the individual (hard to account for). This would need at least a couple of weeks to see if there's a trend as to what day it is and also it helps if you already eat porridge since a total change in diet won't be too influential. Ideally you'd decide yourself to have lunch whenever you feel hungry, rather than having a set lunchtime as you'd probably feel hungry around then out of habit (this is why the observation is a, kind of vague, feeling of hungriness).
