Will carbs make me fat?

Not on their own.

The only way to lose weight is to consume less calories than one requires, independent of protein, fat, or carbohydrate composition. The opposite is also true: to gain weight, you must consume more calories than you require, independent of protein, fat, or carbohydrate composition.

A study discovered that consuming carbs late at night had no detrimental effect on fat reduction.

While carbs might impede fat metabolism, blaming carbohydrates (rather than excessive calories) for weight gain is wrong.
