Final answer:
Negative consequences of too much carbohydrate intake include weight gain, increased risk of type 2 diabetes, elevated blood sugar levels, and higher triglyceride levels.
Step-by-step explanation:
Too much carbohydrate intake can have negative consequences due to the release of insulin in the body. These consequences include weight gain and obesity, increased risk of type 2 diabetes, elevated blood sugar levels, and higher triglyceride levels. When the body receives excess carbohydrates, insulin is released to help regulate blood sugar levels. However, if there is a constant surplus of carbohydrates, the body may become resistant to insulin, leading to these negative outcomes.
