Fourteen subjects (six males) aged 57 (<jats:sc>sd<\/jats:sc>5) years underwent three 4\u00a0d trials in a counterbalanced order: (i) 4\u00a0d on a typical UK diet (40\u00a0% energy from fat, 45\u00a0% carbohydrate and 15\u00a0% protein); (ii) 4\u00a0d on an isoenergetic diet but substituting fat for carbohydrate in line with the present recommendations (30\u00a0% fat, 55\u00a0% carbohydrate and 15\u00a0% protein); (iii) 4\u00a0d on the same recommended diet with 30\u00a0min of brisk walking each day. The food provided for the first 3\u00a0d of each trial was isoenergetic with each volunteer's previously determined daily energy intake. On day 4, the subjects consumed breakfast, lunch and an early evening meal, equivalent in total to 90\u00a0% of their daily energy intake. Blood samples were collected and substrate utilisation and energy expenditure were determined in the fasted state and for 9\u00a0h postprandially. Substrate utilisation differed significantly among trials (<jats:italic>P<\/jats:italic>\u00a0=\u00a00\u00b7003); RER was higher on the recommended diet trial than during either of the other two trials (<jats:italic>P<\/jats:italic>\u00a0=\u00a00\u00b7012 and 0\u00b7021 for the UK diet and recommended diet with walking, respectively). The rise in plasma TAG concentrations over the day was steeper on the recommended diet trial than on the other two trials (trial\u00a0\u00d7\u00a0time interaction,<jats:italic>P<\/jats:italic>\u00a0=\u00a00\u00b7040). The increase in postprandial TAG concentrations associated with substituting dietary fat for carbohydrate was offset by 30\u00a0min of brisk walking daily.<\/jats:p>","DOI":"10.1017\/s0007114508133591","type":"journal-article","created":{"date-parts":[[2008,11,25]],"date-time":"2008-11-25T10:18:44Z","timestamp":1227608324000},"page":"1787-1796","source":"Crossref","is-referenced-by-count":12,"title":["Brisk walking offsets the increase in postprandial TAG concentrations found when changing to a diet with increased carbohydrate"],"prefix":"10.1017","volume":"101","author":[{"given":"Stephen F.","family":"Burns","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrianne E.","family":"Hardman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David J.","family":"Stensel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2008,11,25]]},"reference":[{"key":"S0007114508133591_ref45","doi-asserted-by":"publisher","DOI":"10.1161\/01.ATV.9.2.217"},{"key":"S0007114508133591_ref18","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199108153250703"},{"key":"S0007114508133591_ref9","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/65.4.1027"},{"key":"S0007114508133591_ref47","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ijo.0803754"},{"key":"S0007114508133591_ref6","doi-asserted-by":"publisher","DOI":"10.1161\/01.ATV.12.8.911"},{"key":"S0007114508133591_ref43","doi-asserted-by":"publisher","DOI":"10.1080\/026404102321011715"},{"key":"S0007114508133591_ref1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.18.2284"},{"key":"S0007114508133591_ref31","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1097\/00043798-199502000-00011","article-title":"Walking during the postprandial period decreases alimentary lipaemia","volume":"2","author":"Hardman","year":"1995","journal-title":"J Cardiovac Risk"},{"key":"S0007114508133591_ref10","doi-asserted-by":"publisher","DOI":"10.1053\/meta.2000.8612"},{"key":"S0007114508133591_ref19","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1079\/BJN2001408","article-title":"Exercise prevents the augmentation of postprandial lipaemia attributable to a low-fat high-carbohydrate diet","volume":"86","author":"Koutsari","year":"2001","journal-title":"Br J Nutr"},{"key":"S0007114508133591_ref25","year":"2005"},{"key":"S0007114508133591_ref28","volume-title":"The Composition of Foods","author":"Holland","year":"1991"},{"key":"S0007114508133591_ref3","doi-asserted-by":"publisher","DOI":"10.1210\/jcem-42-4-729"},{"key":"S0007114508133591_ref2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI105472"},{"key":"S0007114508133591_ref20","doi-asserted-by":"publisher","DOI":"10.1161\/hq0901.095553"},{"key":"S0007114508133591_ref42","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/65.2.525"},{"key":"S0007114508133591_ref22","volume-title":"A Report from the Chief Medical Officer.
