Caffeine is a common stimulant that is widely used by many people. Some people drink coffee to wake them up in the mornings. Others drink soda throughout the day to keep them going. If caffeine consumption is limited, it can be beneficial. Too much caffeine can lead to weight gain and negative overall health.
Caffeine is effective at raising the stress hormone cortisol. If cortisol is raised, there are many negative effects. Your heart rate will go up, your blood pressure will rise and your body is told to increase its stores of energy. The need for extra energy will cause the body to have cravings, and these cravings are usually for sweets. Raised cortisol levels are also tied to increased belly fat.
Hypoglycemia is low blood sugar or a drop in blood glucose levels. Glucose is the fuel for the body and when this goes down, the body can not perform as it should. The body will react and crave food for the additional calories that it thinks it needs.
Caffeine can cause the body to be physically, mentally and emotionally stressed. When stressed, depression can set in and we tend to feel bad about ourselves. Stress and a bad self image can lead to emotional eating. Stress also triggers a resistance to insulin. The body will not use the insulin as it should and a side effect will be to store excess fat.
A way to not gain weight from caffeine consumption is to limit the amount you take in. Some caffeine is fine to drink, but there are alternatives that do not cause weight gain. Those include herbal teas, fruit smoothies or just plain water.
