Are you dieting but constantly ravenous? Try flax seed powder/fibre. A couple of respected crossover studies involving just 2.5g dissolved in water resulted in decreased hunger and food intake and the participants consumed an average of 9% less calories in their next meal compared to those who didn’t have the flax seed drink. It is available in good health shops, on amazon and through various online shops (go for organic where possible). My advice: add it to juices and smoothies as it’s a bit gross just with water and have it around 30 minutes before a meal two or three times a day.
