Histamine, Metabolism & Weight
One of the most frustrating histamine-related symptoms for a lot of people is the associated weight problems. And this can be either an inability to lose weight OR and inability to gain weight. If this is an issue for you, don’t despair. Certain whole foods may help.
HOW HISTAMINE IMPACTS METABOLISM
Metabolism is controlled by the brain, particularly in a region of the brain called the hypothalamus. When histamine enters the hypothalamus, it activates several receptors — as though turning switches on or off. Some of those switches have to do with body heat, energy output, and feelings of either hunger or satiety. Depending on a number of other factors, including genetics, level of inflammation in the body, and other coexisting conditions, elevated histamine can lead to weight problems. This can come in the form of excess weight or in difficulty keeping weight on. In general, histamine promotes weight loss. This is due to the stimulation of histamine 1 receptors in the brain which have also been shown to suppress food intake. Animal studies have shown that low levels of histamine in the brain are associated with obesity. So, histamine can help keep us thin. On the other hand, high levels of inflammation (very common with histamine intolerance) can contribute to weight gain. There are a number of different biological pathways in the body by which inflammation leads to weight gain. A couple of these include increased Corticotropin Releasing Hormone (CRH — a stress hormone) and increased glutamate (a stimulatory neurotransmitter in the brain). CRH causes mast cells to release more histamine, and the cycle continues. Glutamate (which also comes as the food additive, Monosodium Glutamate = MSG) stimulates the appetite and causes weight gain. And there are many other pathways in the body that link inflammation to weight gain.

When the body is in balance, we maintain a healthy weight easily. Since inflammation and histamine levels are major reasons for the histamine intolerant person’s imbalance, these two things are a good place to start. To address inflammation, switch to a whole foods, nutrient-dense, anti-inflammatory diet and do what you need to do to get your stress under control. For me, the stress component was just as important as the food component.

HISTAMINE-FRIENDLY-ISH FOODS THAT MAY HELP
Here are some low histamine and/or antihistamine foods that have been shown to have a positive effect on metabolism (particularly for weight loss):
