Important Safety Note
Pregnancy is not a time for weight loss dieting. Even if you're overweight or obese before pregnancy, the focus should be on healthy eating and appropriate weight gain rather than weight loss. Any concerns about weight should be discussed with your healthcare provider who can provide personalized guidance based on your individual health status and pregnancy needs.
