Serotonin can also affect the way people feel about food. Once it's functioning in the brain, it makes the stomach feel full while you're eating, allowing you to regulate the amount of food you eat. Without serotonin, there is a danger that you could overeat.
If you have a problem with mood swings, it could also be because the lack of serotonin in your protein diet failed to regulate your moods.
The problem with protein diets
People who use the protein diet can often severely restrict the amount of carbohydrates in their diet. If it remains uncorrected for a long time, the body can continue to have a strong appetite for food because the amount of serotonin is not enough to regulate the cravings. This is why people will still feel hungry even after a good meal.
Without serotonin, the appetite cannot shut off and mood swings become inevitable. People who use protein diets to lose or regulate their weight can often experience changes in their moods after food has been digested. This usually occurs late in the afternoon or in the evening, a few hours after dinner.
The mood swing can often be followed by a craving for something starchy or sweet. However, if protein is still taken instead of carbohydrates, the person will continue to experience mood swings, become irritable, restless, lethargic and bad tempered.
When using protein-based diets, it's important to consider its effects on the body. If symptoms such as mood swings appear, it might be time to determine whether a few alterations in the diet are required. Mood swings may not be that troublesome initially but if they last longer and occur frequently, they could affect your life and work.
