Weight Watchers Decline: GLP-1s & Business Model Flaws
Nutrition vs.GLP-1s: The Future of sustainable weight Loss
Updated June 13, 2025
following Weight Watchers’ bankruptcy filing, the weight loss industry faces scrutiny. Sami inkinen, Virta Health CEO, believes the ”eat less, exercise more” approach is fundamentally flawed. He argues that these programs, which rely on calorie counting, fail to address the biological roots of metabolic health, making them unsustainable.
Inkinen contends that relying on willpower alone is insufficient for long-term weight management. He emphasizes that obesity is a metabolic disease characterized by persistent hunger and cravings,even with high calorie consumption. Addressing these underlying mechanisms through targeted nutritional interventions or medication is crucial.
According to Inkinen, Virta Health, which he co-founded in 2015, focuses on reversing metabolic disease through nutrition. He says that traditional approaches often miss the mark by not individualizing nutritional recommendations to minimize “food noise,” needless hunger, and cravings.

Inkinen defines robust metabolic health as a state where the body functions optimally, maintaining normal weight, blood sugar, lipids, blood pressure, and inflammation levels. He identifies nutrition as the primary driver of metabolic health, with sleep, exercise, and movement also playing significant roles.
Ultimately everything is biology, including willpower. If you don’t change the biology, you can’t solve the problem of over-eating,” Inkinen said.
He also notes the success of GLP-1s in weight loss, attributing it to their ability to eliminate hunger, cravings, and “food noise.” inkinen asserts that similar results can be achieved through nutrition, as demonstrated by Virta Health.
What’s next
Inkinen envisions a future where weight management combines nutrition and pharmaceuticals, with evidence-based lifestyle treatments and medications like GLP-1s working in tandem. He believes most people can succeed with nutrition alone, while others may require medication.
