Most of the studies that aimed at investigating the association between bread consumption, weight and waist circumference tell a bit of a different story.<\/p>\n<p>It is <strong>white<\/strong> bread which seems to be related to body weight increases and excess abdominal fat. Alternatively, <strong>wholegrain<\/strong> bread does not appear to affect weight gain positively.<\/p>\n<p><a href=\"http:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/sourdough1.jpg\"><img loading=\"lazy\" class=\"aligncenter wp-image-647\" src=\"https:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/sourdough1.jpg\" alt=\"Sourdough\" width=\"700\" height=\"392\" \/><\/a><\/p>\n<p>Although we don\u2019t know for sure how whole-grain bread ensures such benefits it is interesting to list a few <strong>possible<\/strong> ways in which whole grains influence the prevention of excess weight gain. Those are:<\/p>\n<h2>Energy intake<\/h2>\n<p>We have talked before about the effect that wholegrain products have on our <strong>appetite<\/strong>.<\/p>\n<p>They make us feel more satiated relative to refined products. Due to this energy intake is reduced, in other words we eat less.<\/p>\n<p>In addition, wholegrains are <strong>not<\/strong> <strong>as<\/strong> <strong>energy<\/strong> <strong>dense<\/strong>. Hence for a given quantity consumed wholegrain bread will not induce the same weight gain as refined bread.<\/p>\n<h2>Glycaemic index<\/h2>\n<p>The <strong>glycaemic<\/strong> <strong>index<\/strong> (GI) is a value which reflects the effect that a particular food or meal has on an individual\u2019s <strong>blood<\/strong> <strong>glucose<\/strong>.<\/p>\n<p>Wholegrain bread has a low glycaemic index, which means that its nutrients are absorbed and digested more slowly relative to refined one.<\/p>\n<p>As a result gastrointestinal peptides are released that cause us to feel satiated. Again energy intake is restricted.<\/p>\n<h2>Cereal fibre<\/h2>\n<p>There are three ways via which <strong>fibre<\/strong> (contained in wholegrain bread) could potentially influence weight regulation and abdominal fat.<\/p>\n<ul>\n<li style=\"text-align: left;\">Firstly fibre with water make together a <strong>solution<\/strong> which limits the amount of glucose absorbed.<\/li>\n<li style=\"text-align: left;\">Secondly through limiting the amount of insulin produced after the meal fibre may influence the reduction of fat and the <strong>feeling<\/strong> of <strong>fullness<\/strong>.<\/li>\n<li style=\"text-align: left;\">Thirdly fibre affects <strong>satiety<\/strong> through gut hormone. The latter\u2019s effect on satiety is independent of glucose response, in contrast to ways one and two.<\/li>\n<\/ul>\n<p><a href=\"http:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/fiber.jpg\"><img loading=\"lazy\" class=\"aligncenter wp-image-648\" src=\"https:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/fiber-300x206.jpg\" alt=\"fiber\" width=\"700\" height=\"483\" srcset=\"https:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/fiber-300x206.jpg 300w, https:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/fiber-680x469.jpg 680w, https:\/\/www.dimakopoulosi.gr\/wp-content\/uploads\/fiber.jpg 716w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/a><\/p>\n<h2>Gut microbiota<\/h2>\n<p>In this case the mechanism through which gut microbiota may influence weight regulation is based on a <strong>hypothesis<\/strong>.<\/p>\n<p>It is believed that gut microbiota play a role in the extraction of energy from the food we have consumed and help deposit that energy.<\/p>\n<p>If we couple that with the fact that <strong>microbiota<\/strong> composition <strong>differs<\/strong> <strong>between<\/strong> lean and obese <strong>people<\/strong> there is reason to believe that this is another potential way in which whole-grain bread benefits weight regulation.<\/p>\n<p>&nbsp;<\/p>\n<h2>Reference<\/h2>\n<p>Serra-Majem L., Bautista-Castano B (2015) <a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/26148919\" target=\"_blank\" rel=\"noopener noreferrer\">Relationship between bread and obesity<\/a>, <em>British Journal of Nutrition, <\/em><strong>113:<\/strong> S29-S35.<\/p>","protected":false},"excerpt":{"rendered":"<p>The public at large thinks that eating bread is an easy way to add weight.
