Pro­bi­otic yo­gurt linked to fe­male weight loss

Sig­nif­i­cant ben­e­fits found for women in study

A daily yo­gurt — which is known to make stom­achs feel bet­ter, keep di­ges­tive sys­tems run­ning smoothly and may help fend off dis­eases — may also help women lose more weight and keep it off longer, ac­cord­ing to a new study.

A study by re­searchers at Laval Univer­sity in Que­bec sug­gests that pro­bi­otics found in Euro­pean brands of yo­gurt, specif­i­cally those from the Lac­to­bacil­lus rham­no­sus fam­ily, may help women lose twice as much weight as those who don’t con­sume the bacteria reg­u­larly.

Writ­ing in the Bri­tish Jour­nal of Nutri­tion, obe­sity re­searcher An­gelo Trem­blay, a pro­fes­sor in the De­part­ment of Ki­ne­si­ol­ogy, and his team tested their hy­poth­e­sis — that con­sum­ing pro­bi­otics could help re­set the bal­ance of the in­testi­nal mi­cro­biota in favour of bacteria that help pro­mote a healthy weight.

The team put 125 over­weight men and women through a 12week reg­i­men of a weight-loss diet, cou­pled with a daily al­lot­ment of ei­ther two pills con­tain­ing Lac­to­bacil­lus rham­no­sus pro­bi­otics or a placebo.

Re­sults at the end of the 12week pe­riod were sig­nif­i­cant for women, the re­searchers say, with the co­hort among the pro­bi­otic group los­ing on av­er­age 4.4 kilo­grams com­pared to the placebo group who only lost 2.6 kg. For men, there was no dif­fer­ence be­tween the pro­bi­otic and placebo group, which stumped re­searchers.

“We don’t know why the pro­bi­otics didn’t have any ef­fect on men. It may be a ques­tion of dos- age or the study pe­riod may have been too short,” said Trem­blay, who is also the Canada Re­search Chair in En­vi­ron­ment and En­ergy Bal­ance.

For women in the pro­bi­otics group, weight loss con­tin­ued even after the study pe­riod, for a to­tal of 5.2 kg, or twice what the non-pro­bi­otics group lost. Re­searchers fur­ther noted that women in this group had lower lev­els of the ap­petite hor­mone, lep­tin, and lower lev­els of in­testi­nal bacteria re­lated to obe­sity.

The the­ory among the Laval re­searchers is pro­bi­otics may al­ter the per­me­abil­ity of the in­testi­nal wall, keep­ing pro-in­flam­ma­tory mol­e­cules at bay, and thus out of the blood­stream, halt­ing the chain re­ac­tion pro­cesses that lead to Type 2 di­a­betes, obe­sity and glu­cose in­tol­er­ance.

The Lac­to­bacil­lus rham­no­sus strain used in the study be­longs to Nestlé (nine re­searchers from the Nestlé Re­search Cen­ter in Switzer­land also worked on the study), but Trem­blay said pro­bi­otics found in dairy prod­ucts in North Amer­ica may have sim­i­lar ef­fects.

He also stressed, how­ever, that the ef­fects of the pro­bi­otics in­take shouldn’t be viewed in a vac­uum, and the best re­sults for weight loss would oc­cur only within the con­text of a diet low in fat and with ad­e­quate lev­els of fi­bre.
