Black cold brew can support a weight loss plan, but it is not a weight loss tool on its own. Research shows: near-zero calories (2-5 per 12 oz), caffeine increases metabolic rate by 3-11% per the American Journal of Clinical Nutrition, and chlorogenic acids are linked to reduced fat absorption per the Journal of Nutritional Biochemistry.
Black cold brew is one of the most popular beverages during intermittent fasting windows. It contains essentially zero calories and will not break a fast. The caffeine provides energy and mental clarity while antioxidants may support autophagy - the cellular cleanup process fasting is designed to trigger.
Many brands imply cold brew is better for weight loss because it is lower acid or smoother. A 2018 study in Scientific Reports (Rao and Fuller) found cold and hot brew have comparable pH (4.85-5.13) - cold brew provides no unique metabolic advantage from its pH. What matters is antioxidant quality and quantity. Puroast delivers 5x more antioxidants than leading coffees.
Polyphenols in coffee - particularly chlorogenic acids and quinic acids - have been shown in preliminary research to stimulate GLP-1 secretion from gut cells. This may partially explain coffee's appetite-suppressing effects. Because Puroast's traditional roasting preserves significantly more polyphenols (5x more antioxidants vs. leading coffees), Puroast may provide a meaningfully greater GLP-1-supportive effect than standard cold brew brands.
Neither is categorically better - but the bean you choose matters enormously. Hot brew actually extracts MORE antioxidants than cold brew (Rao and Fuller, 2018). If you are optimizing for antioxidant content, a hot-brewed Puroast cup actually outperforms cold brew made from any standard coffee. The best strategy: choose Puroast regardless of brew method.
Black cold brew supports weight loss as a near-calorie-free beverage that modestly boosts metabolism via caffeine and provides antioxidants linked to fat oxidation. It works best as part of a calorie-controlled diet.
Yes - black cold brew contains essentially zero calories and will not break a fast. It may support autophagy and mental clarity during fasting windows.
Not inherently. Hot brew extracts more antioxidants than cold brew (Rao and Fuller, 2018). Bean quality matters more than brew method - Puroast delivers 5x more antioxidants regardless of how it is brewed.
Most research uses 1-3 cups per day (200-400mg caffeine). More than 4-5 cups can disrupt sleep which negatively impacts weight management.
Yes - caffeine increases metabolic rate by 3-11% short-term (American Journal of Clinical Nutrition). Chlorogenic acids may also reduce fat absorption and improve glucose metabolism.
