Eating for two 'unnecessary'
Sorry mummies – but eating for two may not actually be a thing.
Studies have shown that eating for two during early pregnancy is unnecessary – and new research suggests it may be because the digestive system is already prepped for the extra demands of a growing baby.
The good news? It may also explain why some women struggle to lose weight after giving birth.
Pregnant fruit flies, whose genes and metabolism are very similar to humans, were found to have a hormone that triggers fat storage and intestinal growth, which allows more calories to be absorbed from food.
This should, therefore, occur in humans, as pregnant women are also thought to have similar intestinal growth after becoming pregnant. The Medical Research Council Clinical Sciences Centre in London will now be looking to prove this also happens to humans.
But if a mum's hormone levels don't go back to normal, her enlarged intestine may continue to absorb more calories – which could explain some mum's struggle to shift the extra weight.
