Does cutting diet coke out of your system actually cause you to lose weight?

Research is limited: The research linking diet coke to weight gain is mixed. Some feel that drinking an artificially sweet substance can trick your body and lead you to eat more calories. An association has been shown between consuming diet drinks and larger waist size, with possible metabolic syndrome. But this is not a cause-effect relationship, nor does it suggest that stopping diet coke leads to losing weight.
