Don't start dieting too soon
Your body needs time to recover from delivery. Give yourself at least six-week postpartum checkup before you start watching your calorie intake and actively trying to slim down. And if you're breastfeeding, experts recommend that you wait until your baby is at least 2 months old before you try to lose weight.
Be realistic about weight loss
Keep in mind that you may not be able to return to your exact pre-pregnancy weight or shape. For many women, pregnancy causes permanent changes such as a softer belly, slightly wider hips, and a larger waistline.
Lose weight slowly!
Don't go on a strict diet. Women need a minimum of 1,200 calories a day to stay healthy, and most women need more than that – between 1,500 and 2,200 calories a day – to keep up their energy and prevent mood swings. And if you're nursing, you need a bare minimum of 1,800 calories a day to nourish both yourself and your baby. Weight loss of about a pound and a half a week is safe and won't affect your milk supply if you're nursing.
When it comes to losing baby weight after pregnancy, you need all the support you can get — so make sure your partner is on board, too. Instead of watching TV, take a walk tonight. And together, make a commitment to sticking to a diet. Start by ridding your fridge and pantry of high-fat foods; then stock up on fruits and veggies, whole grains, and low-fat dairy products and lean meats, poultry, and fish that are good for you
Eat up – and take your time!
With a new baby and schedule, it can be hard to find the time to eat. But skipping meals can make energy levels lag – and it won't help you lose weight. Many moms find that eating 5 to 6 small meals a day with healthy snacks in between fits their appetite and schedule better.
Finding the time to fit exercise into your daily life, now that you have a newborn, can be tricky. But it's not impossible, as long as you make it a priority.
You can start to do some gentle exercise such as walking, pelvic floor exercises and stretching, as soon as you feel up to it. However, you should wait six weeks or so, or until you feel that you've recovered from the birth, before taking up more strenuous exercise.
Give yourself plenty of time to get back in shape, and don't despair if the weight doesn't fall off immediately. Ignore stories of celebrities getting back into shape a few weeks after childbirth. Such quick weight loss is unrealistic for the average new mum, so take a more gradual approach.
