The 43-year-old fashion designer has taken to chowing down on coffee plant seeds instead of downing a drink when she is out and about with pals, but her eldest son, Brooklyn, 18, is said to not be too keen on the technique.
A source said: "Brooklyn's really isn't a fan. In fact, he's pretty disgusted by it.
"Victoria will quite happily chew coffee beans if tempted to have a drink while socialising."
Victoria — who is known to enjoy a tipple of tequila — is said to have developed a taste for coffee beans to try to avoid hangovers.
The source added to The Sun newspaper: "She wants to remain fresh in mornings and only truly lets her hair down on significant occasions."
The former Spice Girls star's penchant for coffee beans is not the only healthy technique she tries.
Victoria enjoys two tablespoons of apple cider vinegar — which some studies have shown can help with weight loss and boost a person's immune system — on an empty stomach every morning.
Captioning a picture of her breakfast drink, she wrote: "Two tbsp first thing on an empty tummy! X (sic)"
What's more, the 'Spice Up Your Life' hitmaker recently revealed she gives her kids, Brooklyn, Romeo, 15, Cruz, 12, and six-year-old daughter Harper - who she shares with husband David Beckham - a post-school snack of pumpkin seeds and pine nuts in liquid soy protein.
She posted a picture of the seeds and a bottle of Liquid Aminos, a gluten-free alternative for soy sauce, and wrote: "Seeds doused in organic Aminos! Grilled until crispy! After school snack! (sic)"
