After a long plateau, it may seem too good to be true when five pounds is suddenly gone – but the Whoosh Effect is a common experience among keto dieters. Researchers suspect that water retention plays a big role in the Whoosh Effect. When you start keto, you probably increase your water intake. This – along with other dietary and exercise changes – can contribute to the Whoosh.
The takeaway: if you’re currently on a plateau, continue to stick with keto-friendly dishes, exercise regularly, and drink plenty of water.
