Speaking of weight loss, since nuts and seeds are rich in fibre, they help in keeping full for longer and prevent in unnecessary hunger pangs. One tends to eat less after consuming fibre and this ultimately garners the weight loss process. Eating fibre is also helpful in regulating cholesterol levels in the body.
