Why the truth about breastfeeding and weight loss is far from the myth

Does breastfeeding help you lose weight? Serena Williams doesnt think so heres what scientists say

Serena Williams has poured cold water- or rather, cold milk- on the idea that breastfeeding causes the excess weight gained while growing a baby to melt away.

Breastfeeding is widely touted as a means of weight loss, but even though it’s a hungry business as far as the body is concerned, there are several reasons set out above simply sitting back and letting baby suck away the calories often doesn’t cut it.

On average, women lay down 4kg( 9lb) of fat during pregnancy and to lose each kilogram, they will need to create a 7,700 -calorie deficit. Exclusive breastfeeding fees up about 595 calories a day during the first two months of a baby’s life, increasing to 695 calories a day as the baby get bigger. In theory, then, for every week a woman breastfeeds she should be able to lose about half a kilogram, getting back to her pre-pregnancy weight within two months.

But, as many mothers will witness, it is rarely this simple. For one thing, breastfeeding is widely be considered as a licence to feed cake; a generous slice of carrots cake with cream cheese frosting contains about 650 calories; even a skinny blueberry muffin from Starbucks contains 268 calories. Add a grande latte to that, at 230 calories, and you have already pretty much busted any calorie-deficit acquired through breastfeeding.

Of course, girls could stimulate healthier eating choices, but most breastfeeding moms live in anxiety of their milk render drying up- leaving them with an angry newborn, who wants to feed even more often- and health visitors will often advise them to eat more and remainder, as a means of ramping up milk production.

There is also biological pressure to feed more: the breastfeeding hormone prolactin increases appetite, while sleep deprivation- a common side-effect of having a baby- skews the balance of the” thirst hormones” leptin and ghrelin, prompting cravings for sweet, salty and starchy foods. Breastfeeding is another sedentary business, and new mums are often too busy- and too exhausted- to discover time to exercise.

Unsurprisingly, then, analyses that measured the effect of breastfeeding on weight loss have found only a small consequence: a review of five analyzes, which regularly weighed and measured women post-birth, to indicate that after 12 months, breastfeeding mums had lost between 0.6 kg and 2kg more weight than mums who didn’t breastfeed.

It is possible to speed up weight loss without depriving babies of milk, though. Another study found that by restricting calorie intake to about 2,000 calories a day and doing 45 minutes of aerobic exercising four times a week, women lost around 0.5 kg a week without it compromising their milk supplying. Even so, biological changes will mean that some females will find it easier to lose weight, and others harder. The fact that super-sporty Serena Williams struggled to shift her baby weight, despite eating a sugar-free, vegan diet, is testament to that.
