In a preliminary new study, psychoneuro - immunologist Lee Berk and his team at Loma Linda University in California show that the parallels between laughing and
exercise go even
further: Shifts in appetite hormones following a case
of the giggles resemble the effects
of a
moderate session at the gym.
Plaisance says previous research shows that continuous
moderate intensity
exercise does burn more calories, but
further studies have shown that people who perform high - intensity interval training seem to produce the same amount
of weight loss doing 20 minutes
of exercise as those who do 60 minutes
of moderate - intensity
exercise.
