Brenda spoke to RTÉ Lifestyle to give some advice to working mums like herself. The broadcaster and mother of three said that parents need to be kinder to themselves if they make a mistake. "Don't try to be Superwoman!" she says.
The Celeb OpTrans leader admits that living a busy lifestyle with both work and family commitments can be stressful and made even more difficult when trying to factor in a healthy diet and exercise plan.
As a working mum, or any kind of person with a busy lifestyle, give yourself a break. Don't beat yourself up if something goes wrong.
Brenda's advice for having it all? Planning. The radio presenter says that planning her meals has been the key to success and she advises all busy mums to write out their weekly schedules with both family and work events and a meal plan for each day.
"Look at your week, all the different things you have on, all the different taxi journeys you're being made do and look at your food and see what food works for each day.
