In our quest to eat healthily, many often give up croissants, cakes and bread options in favor of smoothies, juices and acai bowls come at breakfast time.

But sometimes, these are not as good for you as you might think.

F45's leading nutritionist, Lyn Green, recently revealed which of her favorite healthy foods are full of fat, calories and sugar.

From the bowls of smoothies to granola, here, FEMAIL takes a look at what you need to be careful.

Words like "natural" and "without added sugar" in the boxes of granola may induce you to think that you are enjoying a healthy snack, although delicious. Lyn (in the picture) said that granola is not always healthy

Big wave

Words like "natural" and "without added sugar" in the granola boxes may induce you to think that you are enjoying a healthy, albeit delicious, snack.

But Lyn revealed to Body & Soul that a crunchy cup can have an average of 597 calories, 28 grams of fat and 24 grams of sugar.

"Many packages of granola sold in your supermarket are loaded with so much sugar that it's not much different from eating chocolate cake with icing, which on average contains 26 grams of sugar," Lyn told the publication.

Instead of opting for granola, nutritionist F45 recommends that you choose buckinis or maybe muesli, which will give you the opportunity without the dizzying sugar levels.

Lyn was quick to point out that the delicious shake bowls (pictured) can contain up to 490 calories and a terrible 67 grams of sugar

Smoothie bowls

Instagram can not get enough of shake bowls at this time.

But Lyn is quick to point out that these delicious bowls can contain up to 490 calories and a terrifying 67 grams of sugar.

The reason why these are so sweet is thanks to the fruit juice, sweetened yoghurts and purees and sauces dumped in them.

If you must eat a bowl of smoothies, make sure they contain a small amount of protein inside them, perhaps by means of a Greek yogurt.

"Juicing extracts all the fiber, vitamins, minerals and nutrients that whole foods contain," Lyn said (pictured)

Juices

Many people turn to juices when they want a hit of health and vitamins.

But many health professionals say that juice is not always the answer and that it is much better to eat a fruit or vegetable.

"Juice extracts all the fiber, vitamins, minerals and nutrients that whole foods contain," said Lyn.

What it does leave is all the sugar in the fruit and, often, a lot.

Instead of eating a juice, Lyn recommends that you try smoothies, which are often more balanced and full.

Refreshments without gluten

The tendency to go dairy-free and gluten-free has exploded in recent times.

But the gluten-free label does not automatically mean healthy.

Lyn said that gluten-free products are often filled with "processed and refined grains" and can be packaged with sugar.

Eliminate these snacks, unless you are celiac and need to eat them.

Nectar of agave

Many say that agave nectar is a nutritious alternative to honey laden with sugar.

But while it is natural, agave is still very sugary, contains 60 calories per tablespoon.

Limit the use of agave and honey, or cut them completely, and you will notice the difference in your waist.
