Drinking turmeric milk itself is unlikely to cause weight gain. Turmeric is a spice that has been used for its medicinal properties for centuries, and adding it to milk can provide additional health benefits. However, weight gain is a result of consuming more calories than your body burns, regardless of the source.
If you add ingredients to your turmeric milk that are high in calories, such as sugar or full-fat milk, it could contribute to weight gain. However, if you use low-fat milk and avoid adding sugar, turmeric milk can be a part of a balanced diet that supports weight management.
It's also important to keep in mind that turmeric milk is not a weight-loss miracle drink. A balanced diet, regular physical activity, and a healthy lifestyle are essential for long-term weight management.
