It has internal validity because what you manipulated (Twinkie eating) affected your dependent variable, but that conclusion does not really bring any enlightenment to your theory.

Internal validity checks for the plausibility of an assumed causal relationship between A and B. Researchers use this measure to estimate how much the independent variable affected the dependent variable. Precise estimation is possible because, in experimental research, we have confident control of the environment and manipulate variability.

In my opinion, the right balance or combination of the two types of validity is more important than a study being high in one but low in the other.
