The secret to successful slimming might just be found under the sea. Recent research in the journal Food Chemistry found that alginate, a natural fibre found in kelp, can slow down fat absorption and promote weight loss. The study suggested that consuming kelp blocks the body’s ability to digest fat by one third. This makes sense, considering that fibre in general, not just the fibre in sea veggies, may help weight loss by boosting feelings of fullness and reducing hunger pangs. Commonly found in seaweed snacks and Japanese cuisine, kelp is low in calories and high in nutrients like vitamins A and C.
