I watched a recent interview of beauty pageant winners, and in the interview, they were asked about their diets and how they achieved weightloss, most of them said they completely eliminated salt. Is it really bad for weightloss?
Salt does cause fluid retention, which can cause weight to fluctuate, depending on the amount of salt you've eaten. While salt can cause everyone to retain fluid, that's more dangerous for some of us than for others.
Salt causes water retention temporarily. Salt can be bad for the heart in large doses, but usually it's association with weight gain is because a lot of unhealthy foods have high levels of salt in them.
