Mushroom coffee for weight loss is having a moment on social media, with health-seekers sipping cups of brewed blends infused with mushroom extract and other ingredients. While these brews can have positive effects, they’re not a replacement for a well-balanced diet full of veggies, whole grains and plant proteins.

Despite some claims, there’s little to no research on mushroom coffee and weight loss. Plus, the brew’s high price tag means you might be better off working mushrooms into your daily meals rather than taking expensive supplements.

Mushroom Coffee for Weight Loss: Does It Work

For starters, the brew’s caffeine content is likely to boost your energy level and contribute to weight loss (through increased metabolism), but only temporarily. People develop a tolerance to caffeine over time, and when that happens, the jittery feeling and energy boost can actually result in fewer calories burned and an overall slower metabolism.

Additionally, some types of medicinal mushrooms used in the brew (including chaga) contain high levels of oxalates, which can cause bloating and increase your risk for kidney stones. If you have kidney or digestive problems, avoid this type of mushroom coffee or add it sparingly if your doctor approves.

As far as boosting your mood, the mushroom ingredients in mushroom coffee may have some benefits, but the brew is also high in sugar and fat, making it an unhealthier option for anyone who wants to lose or maintain weight. In addition, drinking too much mushroom coffee can make it difficult to sleep, and poor quality sleep can lead to overeating and weight gain.
