While nothing bad will happen by eating a lot of avocado, keep in mind that the serving size is a lot smaller than you might realise meaning you may be consuming a lot more kJs than you intended to, says Keri Gans, registered nutritionist and author of The Small Change Diet.
The serving size that I don’t think anyone sticks to is one-fifth of a medium-sized avocado, Gans tells Yahoo Health. Most people think you’re supposed to eat the whole thing, like with any fruit.
But consider that an avocado packs around 1,000 kilojoules. So it’s not the same as eating a whole peach, which is 250 kJs. There’s a difference — and if you are watching your weight, you probably don’t want to eat an entire avocado, Gans says.
