Furthermore, eating too much sugar makes you overeat by suppressing the hormone leptin, which tells the body when to stop eating. If you feel tired and lethargic after consuming sugar, you are also less inclined to exercise.
An increase in blood sugar stimulates insulin production to bring it back to normal levels. Insulin lowers blood sugar levels: when it fluctuates or drops too low, your body thinks it needs more fuel. As a result, you eat even when you don’t really need to.

Too much sugar weakens the immune system. This is because glucose reduces the activity of white blood cells, which are responsible for eliminating pathogens like viruses. Regularly eating too much sugar makes us more susceptible to contagions because our bodies are less capable of fighting them off.

Many people find sweet tastes pleasant. Our tongue gets used to different flavors, and sugar is no exception. British researchers discovered that overweight individuals have a decreased sensitivity to sweetness and a preference for sweet foods. In the same study, healthy and fit individuals who started drinking 2 sodas a day experienced dulled taste buds and sugar cravings after just 4 weeks.
