Jakarta, August 26 2026 — For people living with overweight or obesity, losing weight is often only part of the challenge. The body can adapt to prolonged excess weight by adjusting the brain’s perception of its “normal” body weight, making it harder to maintain weight loss. Changes in appetite-regulating signals can increase hunger and reduce feelings of fullness, making it more difficult for patients to sustain their progress over time.
Among the hormones involved in this process are GLP-1 (Glucagon-Like Peptide-1) and GIP (Glucose-Dependent Insulinotropic Polypeptide), two incretin hormones produced naturally by the gut in response to food. These hormones play an important role in regulating blood sugar, appetite, and satiety, while also influencing food cravings and what is increasingly referred to as “food noise”—persistent thoughts or urges related to food.
Against this backdrop, LIGHThouse Clinic, a pioneer in weight management in Indonesia with more than 22 years of experience, is introducing two tirzepatide-based treatment options, TirzePen and TirzeSlim. The therapies are designed to complement a comprehensive, medically supervised approach to weight management.
“People often blame themselves when they struggle to lose weight or maintain weight loss, assuming it comes down to a lack of discipline. But weight regulation is far more complex than that,” said Dr. Guadelupe Maria Melissa, Medical Manager of LIGHT Group.
“When a person loses weight, the body can respond by increasing hunger and reducing feelings of fullness through changes in hormonal and appetite-regulation pathways. This is why effective weight management needs to address the biological mechanisms behind appetite, rather than focusing on willpower alone. Tirzepatide works by activating both the GLP-1 and GIP pathways, which are involved in appetite and satiety regulation. For appropriate patients, this may help reduce hunger, improve control over food intake, and lessen persistent thoughts or urges around food, commonly referred to as food noise.”
Dr. Guadelupe emphasized that medication is not a standalone solution. While injection therapy can play an important role in managing appetite and supporting weight loss, long-term success also depends on sustainable changes in eating habits, nutrition, and lifestyle.
“Treatment does not end with an injection,” she added. “Patients need the right nutritional guidance, medical monitoring, and ongoing support to help them build habits that can be maintained over the long term.”
The approach also addresses food noise, a term used to describe persistent or intrusive thoughts about food, cravings, or urges to eat. While food noise is often dismissed as a matter of willpower, it can be influenced by biological, psychological, behavioral, and environmental factors.
LIGHThouse Psychologist Tara de Thouars said the psychological dimension of weight management should not be overlooked.
“Food-related behavior is influenced by much more than hunger. Our mindset, emotional state, relationship with food, daily routines, and environment can all shape the choices we make,” Tara explained. “When unhealthy eating patterns become established, addressing the underlying thoughts, emotions, and triggers is an important part of creating lasting behavioral change.”
For this reason, LIGHThouse’s approach to obesity management extends beyond the number on the scale. For more than two decades, the clinic has combined medical care with nutrition education and behavioral support, recognizing that successful weight management involves both losing weight and maintaining the results.
Nutritionists help patients develop realistic and sustainable eating patterns, while psychologists help identify emotional triggers and behavioral patterns that may contribute to weight gain. Together with medical supervision, these components form a multidisciplinary approach designed to support patients throughout their weight management journey.
With the introduction of TirzePen and TirzeSlim, LIGHThouse is expanding its treatment options while maintaining this multidisciplinary approach. The goal is to provide patients with a more comprehensive pathway to managing obesity and improving metabolic health—one that addresses not only weight, but also the biological, nutritional, and behavioral factors that influence it.
