Fanny Lécossais, known to viewers from the TF1 docu-reality series Familles nombreuses : la vie XXL, detailed her weight loss progress and dietary changes on her Instagram account on Monday, October 5, 2026. The 44-year-old mother of five reported losing 13 kilograms so far, reaching the halfway point of her overall target.
Television Appearance Sparks Weight Loss Journey
Reflecting on her weight gain, Lécossais explained that she lost all the weight from her pregnancy with Thess. Following her subsequent pregnancy with Arya, however, her eating habits changed.
Lécossais gained more than 25 kilograms over an 11-month period, reaching a weight of 80 kilograms.

The catalyst for her weight loss journey arrived when she watched herself on television. My God, what is this woman,
she recalled thinking upon seeing her appearance on the TF1 program, adding that she refused to buy new clothes because the only size that fit her was XXL.
Dietary Rebalancing Leads to Rapid Weight Loss
To achieve her transformation, Lécossais adopted a specific dietary structure alongside the use of daily food supplements announced in her October 5 social media video. Her dietary rebalancing consists of two tablespoons of starchy foods, a source of protein, and vegetables ad libitum at every meal.
The adjustments yielded rapid initial changes. During an episode broadcast on Tuesday, September 22, the mother of a large family revealed a loss of 10 kilograms achieved in just one month and a half.
Lécossais Aims for Target Weight of 55 Kilograms
Despite dropping 13 kilograms and noticing that her clothes fit less tightly while her stomach has visibly slimmed, Lécossais is not yet finished with her plan. She aims to lose another 15 kilograms to reach a target weight of 55 kilograms for a height of 1.59 meters.
The reality television participant hopes to accomplish this final stretch before the birth of her first grandchild, while also noting that she does not rule out future cosmetic surgery to firm her stomach area.
Content Creator Offers to Help Other Women
The content creator, who proposed helping or accompanying other women in this approach, expressed her satisfaction on social media: I am so happy (…) I feel deflated, lighter, and prettier.
The participant, who is married to a former professional footballer, appears with a different silhouette from her beginnings in the show alongside her husband Thomas Lécossais and their six daughters, having also shared a photograph dating from 2020.
