Health
Are e-cigarettes good for quitting smoking?
Multiple randomized controlled trials show FDA-approved treatments (varenicline, combination NRT) achieve similar or higher quit rates than e-cigarettes. While e-cigarettes help some people quit, claiming they are THE MOST effective method is not supported by current evidence.
Health Does cannabis help with anxiety and depression?
Current evidence does not support cannabis as an effective treatment for anxiety and depression, with studies showing it is associated with worsening of these conditions in many users. While some individuals report symptom relief, controlled trials have failed to demonstrate therapeutic efficacy comparable to established treatments.
Fitness Does fasted cardio burn more fat?
Exercising on an empty stomach is associated with higher fat oxidation rates during the exercise session itself, with increases of 20-50% compared to exercising after eating. However, this increased fat burning during exercise may be partially offset by reduced fat oxidation later in the day, and the overall impact on 24-hour fat loss remains unclear.
