Why cutting carbs makes you grumpy

Yam Cup Remedy for Cheer Up!

Many consumers choose a low carbohydrate, high protein approach to loss weight. This method is often accompanied by mood swings and irritability... Why? Serotonin, the fiercely “feel good” neurotransmitter is partially controlled by food intake. When carbohydrate foods are consumed, insulin is released which allows tryptophan (an amino acid) to enter the brain in larger amounts since "other" competing amino acids have been diverted to the muscles for synthesis. What does all this scientific jargon mean? A higher presence of tryptophan in the brain increases the production of serotonin and HAPPY sets in. When carbohydrate foods are cut from the diet, serotonin production is reduced allowing the grump to slip out.
