Researchers say there's a pretty simple way to keep people from falling off the diet wagon.
Mayo Clinic researchers have found that people who got financial incentives to lose weight lost more than people who didn't get any money.
They did the study on Mayo Clinic employees and their family members. Almost two-thirds of the people who got paid for losing weight lost four pounds a month, compared with only about a quarter of the non-incentive group.
A new study shows a diet with too much sodium may trigger some autoimmune diseases.
Autoimmune diseases cause the immune system to attack healthy cells. They include illnesses like Type 1 diabetes, psoriasis, multiple sclerosis and rheumatoid arthritis.
Researchers say the number of people with autoimmune diseases has increase in the western world, and they think it may be because of dietary changes like increased salt intake.
Experts say this means more people with autoimmune illnesses should consider going on a low-salt diet.
