Jackie Matubia reveals 4 kg weight loss in 1 week as she battles cortisol
By Valerian Khakayi, September 8, 2026Kenyan actress Jackie Matubia has revealed that she has lost 4kg in one week as she works on her weight and cortisol levels.
The actress shared the update on social media, celebrating the progress while thanking Fahma Clinic for its support.
“Yaap 4kgs down in one week and dealing with my cortisol thanks to @fahmaclinic,” Matubia wrote on Tuesday, September 8,2026.
Her post suggests that Matubia may be receiving professional assistance as she works towards her weight-loss goals, after she tagged and thanked Fahma Clinic for its support. However, she did not disclose the specific treatment or procedure she may have undergone to achieve the reported 4 kg weight loss.
Fahma Aesthetics is a Nairobi-based medical aesthetics and body-transformation clinic located at Greenhouse Mall along Ngong Road. The clinic says it specialises in bespoke weight-loss programmes, body sculpting, facial enhancement and skin rejuvenation.
Among its services is the Fahma Weight Loss Plan, as well as fat-dissolving and body-sculpting treatments. The clinic’s current service listing also describes the weight-loss plan as involving professional guidance.
What is cortisol?
Cortisol is a hormone produced by the adrenal glands and is commonly known as the body’s “stress hormone”. It plays several important roles, including helping the body respond to stress, regulating blood pressure and blood sugar, and supporting metabolism.
The body naturally produces cortisol, with levels changing throughout the day. Stress can also cause cortisol levels to rise temporarily.
Having unusually high or low cortisol levels can, however, be linked to health problems. For example, persistently excessive cortisol can occur in conditions such as Cushing’s syndrome, although this is a rare condition.
Matubia did not say that she has been diagnosed with a cortisol-related medical condition. Her statement simply indicates that managing cortisol is part of what she is currently focusing on.
The actress has previously been open about her body and weight-loss journey, and her latest update gives her followers a glimpse into her current efforts as she works towards her desired results.
