Raw Food Diets: They Actually Do More Harm Than Good

Weird and wacky diets like raw food diets, juicing, liquid diets, intermittent fasting, and carb backloading are becoming more and more common and being followed by everyone in a quest to lose weight and see results.  It’s easy to understand why so many people follow these crazy diets.  When people are desperate they do strange things, and there is also an abundance of miss informed information and clever marketing schemes which litter the internet, ready to take the money off the next poor soul who gets sucked in.  In this article, I’m going to cover all the dangers of a raw food diet.


What Is A Raw Food Diet?

A raw food diet is generally a vegan-based diet that focusses on consuming foods that involve little to no cooking.  These foods will also have gone through minimal processing if any.  There are some exceptions to the rule, which allow some foods to be heated to 140 degrees (F) only.  This is because raw food diet followers believe you are killing all the nutrients in food when heated to extremely high temperatures.  This isn’t entirely untrue as nutrients like protein can become denatured when heated at extreme temperatures.

Following a raw food, diet isn’t all doom and gloom, there are definitely positives, it’s just they are massively outweighed by the drawbacks.

Dangers Of A Raw Food Diet

It’s time to talk about some of the dangers of following a raw food diet.  If you are planning to start one of your own, then please make sure you are aware of all the things I’m going to discuss below.

Are You Getting Enough Calories?

A huge problem with raw food diets is the difficulty you will have in consuming enough calories across the day.  You may be thinking fewer calories is a good thing, especially when you are trying to lose weight.  This is true, to lose weight you will need to be in a calorie deficit.  However, if your calories are too low then you will be causing more harm to your body then good.

No matter what you currently weigh your body needs a certain amount of calories just to simply maintain its self and function properly.  This may be 2100 for one person and 2900 for another.  If your daily calorie consumption falls massively below this level your body could potentially shut down any systems it believes to be “not critical”.  Oh, and it’s also important to note your body will also stop using fat for fuel, which goes against what 80% of people actually want from dieting, “to lose body fat”.

Below are some clear signs you can keep an eye out for that indicate you are probably not getting enough calories.  I would like to add I am not a doctor and many of these signs could indicate other problems you might have.  However, if you are trying to lose weight by following a raw food diet and experiencing any of these signs, then the chances are your calories consumption is way to low.

  1. Experiencing dull headaches
  2. An inability to stay warm
  3. Stomach cramps
  4. Extreme fatigue and muscle weakness.

It can be incredibly hard to consume enough calories when following a raw food diet 100% of the time.  Click here to see how many calories you should be having to safely lose body fat.  If your calories from your raw food diet fall well below the safe amount you should be consuming, then you really should consider making some changes.

Eating Raw Food Could Cause Cholesterol Problems…..Yup you read that right

A raw food diet will usually be rich in vitamins and minerals, however, many foods you can eat raw will be lacking in healthy fats.  This may lead to the blood levels of HDL’s (high-density lipids) being to low.   This is your good cholesterol.

The main way to increase your HDL levels is through your diet, however, they can also be increased through losing weight and exercise.  If you are not getting enough healthy fats in your diet then you will naturally increase the risk of heart disease.  I would always see a doctor and get your cholesterol monitored if you are thinking about following a raw food diet.

You May Be Starving Your Body Of Some Important Nutrients

When following a raw food diet you will be getting an abundance of vitamins and minerals, however, you are also at risk of some serious nutrient deficiencies as well.  These mainly being vitamin D, calcium and vitamin B12.

Out of the three, calcium may be the easiest to come by as there are some plant sources which many consider superior to other food sources containing the mineral calcium.  The downside is the lack of variety, and you will need to include the same plant sources every day in your diet.  However, when it comes to vitamin B12 it’s a different story.  A raw food diet has very limited options for vitamin B12.  One of the main non-animal sources I can think of is fortified cereal.  The problem here is, it doesn’t really fit into the raw food equation due to being processed.  This stops many true raw food dieters from having it.  There are many symptoms you may experience from a vitamin B12 deficiency.

  1. A decrease in appetite
  2. Fatigue
  3. Constipation
  4. Depression
  5. Problems with balance
  6. A tingling sensation or numbness in your hands or feet

When following a raw food, vegetarian or vegan diet, you can of course supplement with vitamin B12 tablets, however, this again goes against what many raw food dieters believe in.  The other options are injections or drops.

Osteoporosis caused by a loss of bone density is something you really need to be aware of if you are deficient in vitamin D and calcium.  It’s vitally important to get checked out and make sure you have sufficient levels of these nutrients.  Supplementing is always an option if your levels are to low.

Constipation, Bloating, Excess Gas…Who Wants Any Of These?

By suddenly eating countless amounts of vegetables, fruits, unprocessed grains, nuts and seeds you will be suddenly adding a large amount of fibre to your diet.  That’s surely a good thing, right?  Unfortunately not.  Yes, fibre is vitally important, however, you should in general only be consuming the recommended amount of 20 to 35 grams a day.  Also if you are looking to add more into your diet, then this should be increased very slowly to allow your body time to adapt.

If you suddenly change to a 100% raw food diet, then you will be suddenly increasing your levels of fibre to some quite extreme levels.  You may then experience stomach pains, bloating, constipation and excess gas.

If you really are looking to change to a raw food diet, then gradually introduce the raw foods over a period of a month or two.  This will slowly increase your fibre and help you to avoid any of the problems above.


Should You Try A Raw Food Diet?

My answer to this question is a simple no.  I truly believe following an entirely raw food diet will only lead to more harm than good.  As well as all the reasons above, I’m going to list below some other things you need to consider before trying this diet.

  • A raw food diet requires incredible organisation, discipline and preparation to make sure
    you are getting an adequate amount of many essential nutrients the body requires.
  • Staying motivated when eating out and socialising will be a huge test for you.
  • Cooking food has its benefits as it kills harmful compounds, bacteria and toxins.

I have talked so much about vegan style raw food diets.  There are, however, some people who will attempt to eat raw meat.  Please take extreme caution when eating raw animal products.


Final Thoughts…Are There Any Positives

As you can see, there are many downsides to doing a 100% raw food diet.  For anyone already doing one, this may have been hard to read, especially when there is so much hype about them on the internet.

Although following this diet 100% of the time, in my opinion, is not a great option, if you have a balanced diet which includes some raw foods then you will experience all the health benefits and none of the negatives.  People who include some raw foods in their diets have reported, increased energy levels, better digestion and clearer skin.  I think the take-home point here, is that balance is key.  Regardless of what it is, too much of one thing will generally always lead to problems.
