1. Strangely... your breath might get worse...

Diets with no carbohydrates have been directly linked to bad breath. As the body produces ketones for energy in the absence of glycogen, these ketones are removed through urination and exhalation. The exhalation of these ketones can lead to bad smelling breath.Original content sourced from

2. Great! Your risk of diabetes might decrease

Carbohydrates are broken down into glucose, therefore cutting out carbohydrates will significantly reduce your chance of developing diabetes. Good alternatives to eat can be lean proteins, such as fish and chicken as well as removing sugary drinks.

3. Oh dear... Your Energy levels Could Drop

As humans we need energy in order to perform everyday tasks, whether that's walking your dog or driving to work. Without carbohydrates we lack the fundamental energy source, making you less productive and sluggish throughout the day.

4. You'll spend more £££ on food

Carbohydrates are most often the cheapest foods on your plate. By cutting these from your diet, you're becoming dependent on fats and proteins for energy, which are typically more expensive in the vast majority of supermarkets. This is even more noticeable with the ongoing cost of living crisis.

5. You might just get a worse night's sleep

When your body is hungry it can't relax, so when it comes to settling down for bed you may take longer to sleep or even be unable to sleep. Researchers have also proven carbohydrates are responsible for 2 brain chemicals, tryptophan and serotonin, which are involved in sleep.

6. You may struggle on the toilet

If you thought removing carbohydrates would reduce your time on the toilet then you would be mistaken. No-carb restrictive diets can be very low on fibre. Fibre is important for digestion since it helps maintain bowl regularity. Removing carbohydrates from your diet can therefore lead to constipation and digestive discomfort .

7. Believe it or not! You may lack some vitamins/minerals

When removing carbohydrates from your diet, you may lack in vitamins and minerals. Potassium, B vitamins and vitamin C are just 3 examples.

Completely removing carbohydrates from your diet will drastically limit your options when it comes to eating. The foods your body craves and enjoys, such as crisps or cookies are no longer on your menu. You will become restricted to bland, unappetising foods which you just won't want to eat.

11. Your teeth will be healthier

Eating a lot of simple carbohydrates can be very damaging for your teeth. When sugar reacts with plaque on your teeth it forms acid. This will slowly break down the enamel which causes your teeth to rot, leading to fillings or even having your teeth removed.

31. You'll Drop The Water Weight

Carbohydrates make us retain water in our body - which is not a bad thing it keep the body hydrated. But, when you ditch the carbs you will drop this water weight. So you may notice yourself instantly losing the pounds. As soon as you start eating carbs again this water comes back.

32. You May Feel Dizzy

There are some nasty side effects to dropping out the carbohydrates completely. One of these is that you may feel dizzy. Your body functions best with some carbs so adjusting will take a while. The sensation should be temporary and not last too long however.

33. You May Feel Fatigued

 It's common knowledge that carbohydrates give us energy. So, it makes sense that if we cut these out of our system we will feel fatigued. Your body will learn to use other energy stores. So, this feeling of fatigue may be temporary or it could stay.

34. You May Initially Bloat

This is a side effect that many people don't factor in because they usually think you will instantly get slimmer. But this is not the case. Your body will be eating more of other foods which contain more gas that carbohydrates so you may look a little bloated for a while.

38. It Could Make Anxiety Worse

It has been shown that people with low-carb diets over time had less serotonin (the molecule of happiness) in their brains than those who were on low-fat diets. Healthy serotonin levels help fight against anxiety and depression. So cutting them out won't give you that boost anymore.

39. It Can Dehydrate You

Carbohydrates store water in our bodies and so when these are removed a lot of our water retention goes. It can lead the body dehydrated so you have to be careful to drink extra water and stay properly hydrated if you are considering no carbs or the keto diet.

40. You May Look More Toned

43. It Could Lower Your Sex Drive

This is something that is a continuation from the previous point - it's to do with hormones. The decrease in hormone production can lead to a lower sex drive. For example in men, your production to testosterone may dwindle, leaving you with less of a sex drive than before.

44. Your Immune System Will Weaken

 Carbs in our diet help with our gut, our hormones...and a whole host of essential functions for our body. So when we aren't fuelling our body with any carbs of course your immune system may weaken and you may find yourself more prone to catching viruses.

For a while when you cut out carbs you may find yourself feeling nauseous and a little bit sickly. After all, carbohydrates are a normal and good part of a natural and balanced diet. The body needs them to function properly. So while you adjust, this is a side effect.

47. Skin May Worsen

When you cut out carbohydrates, you interfere with the bacterias in your gut which are completely necessary for our digestion. But, when you drop carbs from your diet it can mess up these bacteria and poor gut health is directly linked to skin problems.
