The Keto Diet: Good, Bad or just Dangerous?

Let’s be honest, a weight loss plan that doesn’t require more gym time or constantly gnawing on meat bones sounds appealing, right? Which is why searches for Keto Diet  or Ketogenic Diet to use its full name have quadrupled in the last year. 

Famously not for the faint-hearted, or those who think ‘one snack won’t hurt’, this low carb diet plan is often referenced as the fastest way to getting a lean aesthetic. This is because the keto diet forces your body into a metabolic state called ketosis (more on this later).

Online it has many monikers – ketogenic diet, low carb diet, low carb high fat (LCHF), etc – however, to eat your way into ketosis the food principles are the same: very low carb, medium protein and high fat. 

With celebs from Kim K to Anne Hathaway reportedly fans, WH shines the spotlight on the eating plan that requires commitment, willpower and a fat load of food. 

What is The keto Diet?

As mentioned, the formula for ketosis is pretty simple: low carb, moderate protein and high-fat diet. This mix of macros balances the hormones behind metabolism – specifically, insulin, gherlin and leptin. By replacing your daily carb intake for fat (hold the quinoa, add extra cheese) you stop your body from using glucose for energy and force it to burn fat.

The margins for the ketogenic diet are tight. You want to get 60-75% of your calorie intake from fat, 15-30% from protein; leaving only 5-10% from carbs. Also, your daily net carb allowance (carbs without fibre) is capped at 50 grams, and preferably under 20 grams. Any higher and your body will start to feed off glucose which defeats the purpose. Keep kitchen scales handy when meal prepping to avoid slipping up.

As your carbs/protein/fat targets are so specific nutritional labels will become your best friend. However, don’t be misled by ‘low-carb’ foods as these generally have a high sugar content. Instead, cook from scratch with foods naturally low in carbs and favour grass-fed meats and leafy greens. Don’t forget to refresh yourself on how to count your macros – fail to prepare and prepare to fail. 

It might sound complicated, but once you’ve embraced the change in your shopping and prepping habits the rules become second nature. Plus, firing up your metabolism means you don’t need to sweat every day in the gym to burn fat, freeing up mornings and evenings to embrace other healthy things to do. 

But is this low carbohydrate diet safe for everyone?

‘The ketogenic diet is quite a dramatic change in diet, that requires you to exclude a number of foods, which if not carefully managed can lead to vitamin and mineral deficiencies and side effects over time,’ warns Rick Miller, Clinical and Sports Dietician.

‘Anyone under 18-years-old and pregnant women should not follow the ketogenic at all without the guidance of their doctor. I would also advise anyone with disturbances in their blood glucose (e.g. those with diabetes), who may have gallstones, a chronic bowel condition (such as irritable bowel syndrome), existing bone problems (such as osteoporosis), an eating disorder or taking any type of medication to check with their doctor before starting.’

Neither pregnant nor still at school? Still, proceed with caution: ‘Following the ketogenic diet can lead to vitamin and mineral deficiencies and side effects over time.’

Keto Diet Side Effects 

Getting your body into ketosis requires a commitment to eating low carb longer than a one-day meal plan. It can often take up to seven days for your body to run on ketone bodies, the fat-derived fuel. That said, because of the nutritional restrictions which have been known to cause fatigue, dizziness (from a large reduction in blood glucose), gastrointestinal discomfort due to the high-fat content of the diet, bad breath and occasionally nausea you should seek medical advice before attempting to eat the keto diet from now on. 

‘There is evidence that those who follow a keto diet in the longer term have suffered complications, such as nutritional deficiencies and muscle wastage,’ says Miller. ‘In other research where the participants are performing resistance training, there seems to be little to no effect on loss of muscle tissue. The biggest effect on the time limit, will be the degree to which the person is able to maintain the restrictive nature of the diet as it can make social eating difficult without some planning.

Keto Diet Food List 

 Do indulge with these food rules. 


Grabbing a handful of these will keep you satisfied and provide you with healthy fat.


Removing ‘skinny’ from your morning coffee order is an easy way to increase fat intake, although you’ll have to sacrifice the carby croissant.


Wave goodbye to one cal spray. Whether it’s olive oil, coconut oil or, wait for it…. butter, you don’t have to scrimp.


Stop yourself reaching for your carby old faithful (pasta & pesto in our case) by preparing evening ketogenic dishes from your weekly meal plan in advance.


Asparagus, chard, spinach and lettuce can be had in abundance. Load up your plate with these instead of reaching for extra protein or carbs


To master the Ketogenic Diet sticking to nutritional percentages is key; you won’t know them unless you’re accurate.

However, these foods are not keto and are off the menu.


Crackers, oats, rice, pasta, bread, pizza all have to go. Don’t think your rye or spelt loaves are exempt either; it’s all contraband. Instead sub in low carb veggies, like cauli rice and courgetti in your dinnertime faves.


 Any sugary cocktails, beers, ciders and sweet wines are out. For the occasional tipple go for a G&T or small glass of dry white.


They may be vegetables but potatoes (even the sweet ones) are too carb heavy for the keto diet. Also, your usual dollop of ketchup needs to be replaced with a fresh salsa. Shop bought condiments don’t make the cut, but their homemade alternatives can be consumed with relish.


They’re too processed. Reducing fat intake or upping sugar goes against the whole keto philosophy


Yes, it’s heartbreaking, but on the ketogenic diet hummus is officially enemy no.1.


Shop bought cakes, ice cream and confectionary all have to be cut. Seem obvious? It’s not just refined sugar, healthy food faves like agave syrup, dried or tropical fruit and honey are all on the hit list. Make up for it by whipping up these ketogenic friendly cookies.
