Why you may weigh more in the morning without actually gaining fat

New research suggests that the body's water content shifts throughout the day, causing weight fluctuations of up to 2-4 pounds. This is due to changes in hydration levels and the body's sodium balance. The study, published in the journal Obesity, found that people typically weigh the most in the morning and the least in the evening. The findings could help people better understand their weight fluctuations and avoid unnecessary dieting.
