Bottom lineWait until your body has recovered - generally after the 6-week check - before actively dieting, and focus on balanced eating rather than strict calorie cutting; if breastfeeding, avoid sharp restriction to protect milk supply.

It's best to wait until your body has recovered before actively dieting - generally after your 6-week postpartum check, and even then to focus on healthy eating rather than strict calorie cutting. If you're breastfeeding, take extra care not to restrict too much.

Why waiting matters

The early weeks are for healing. Your body needs good nutrition to recover from birth, rebuild tissue, and (if breastfeeding) make milk. Strict dieting too soon can slow healing, sap your energy, and reduce milk supply.

A better early approach

Rather than "dieting," aim for:

• Balanced, regular meals with protein, whole grains, fruit, and vegetables
• Plenty of fluids
• Gentle activity like walking, building up as you heal

When to step it up

After your 6-week check (and once your provider confirms you've recovered, longer after a C-section), you can gradually increase activity and, if you wish, aim for slow weight loss of about 0.5-1 kg (1-2 lb) a week.

If you're breastfeeding

Don't drop your calories sharply. Eat enough to support milk production and lose weight slowly. A dietitian can help you do this safely.
