How chia seeds help with weight loss
It all comes down to fiber and protein, two things that chia seeds are packed with.

-
Use the correct size. While there is no official diet for weight loss, one to two tablespoons a day is a good place to start. “This amount provides meaningful fiber and nutritional benefits without contributing extra calories,” says Bazlian.
-
Combine them with liquids. Chia seeds form a thick gel when you chew them, which makes them easier to eat, says Imus. (A tablespoon of dry chia seeds can be difficult to swallow and may pose a possible choking hazard.) If you plan to eat the seeds on their own, mix a tablespoon or two with at least 8 ounces of water.

The chia seeds absorb some of the liquid from the fruit and make it a spreadable fruit,” says Bazilian.

Use them as an egg substitute. Chia gel can work well as a binder in baked goods. To make chia “eggs,” mix 1 tablespoon of whole chia seeds with 3 tablespoons of water, recommends Harvard’s TH Chan. Let the mixture sit for at least five minutes, until it is slightly thick, like a raw beaten egg.
