Around 45 million Americans go on a diet every year. Yet, despite all the different types of diet available, we're still facing an obesity crisis. 

Believe it or not, there's more to health than 'calories in-calories out.' Diet deficiencies can not only impede weight loss progress, but they can also give you unwanted adverse symptoms. 

If you're thinking about going on a diet, you're at risk of nutritional problems. However, don't worry because blood tests for diet deficiencies can help you identify where you're going wrong. 

Read on for a simple guide to the lab tests for diet deficiencies in the most popular diets. 

Atkins and Low Carb Diets

The Atkins diet was created in the 1970s and is a low-carbohydrate, high-fat, high-protein diet. People often lose weight in the early stages of the diet.

However, it's not considered sustainable long-term, because carbohydrates are an essential food group that includes vitamins and minerals necessary for health.

If you're on the Atkins diet and you're noticing symptoms such as fatigue, dizziness, and muscle weakness, you might have undiagnosed deficiencies. 

Anyone on the Atkins diet or following a low-carb variant diet should have lab tests for vitamin D levelscalcium, and electrolyte deficiencies

The Zone Diet

The Zone diet is an anti-inflammatory diet designed to improve health and reduce weight. However, on this diet, dairy intake is restricted - this leads to many missing nutrients.

The risk factors for calcium deficiency are high on the Zone diet. If you're experiencing muscle spasms, tingling, or burning sensations on your skin, get blood tests for calcium deficiency immediately. 

Raw Food Diet

The raw food diet is trendy amongst those trying to be healthier and those losing weight. However, the variety in your diet is very limited when only eating raw foods. 

Therefore, deficiencies are widespread. Watch out for any symptoms of vitamin B12iodinecalcium, and vitamin D deficiency. These can include tiredness, being cold, itchy skin, and muscle spasms. 

If you're having multiple symptoms and can't pinpoint them to a specific deficiency, a full nutrient panel test can help you understand why you're experiencing these symptoms. 

Ketogenic Diet 

The keto diet (high-fat, low-carb) has been steadily gaining popularity in recent years as influencers promise instant weight loss and better cognitive function.

However, there are concerns around heart disease if this diet is followed for prolonged periods due to the recommended high fat intake. 

Furthermore, keto diet deficiency is common when it comes to the B vitamins (usually found in carbohydrates). Symptoms of B vitamin deficiency include tiredness, constipation, and numbness in the hands and feet. 

Vegetarian and Vegan Diets 

Vegetarianism and veganism have become some of the trendiest diets recently. Many opt for this lifestyle for both health and environmental reasons. When done right, these diets can be sustainable long-term. 

However, meat contains essential amino acids and vitamin B12 that can't be found in vegetables, so multivitamin supplementation is usually recommended for vegetarians and vegans. Meat is also rich in iron; you're at high risk of iron deficiency if you aren't careful. 

Vitamin B12 deficiency and vitamin B6 deficiency symptoms include yellow-tinged skin, a sore tongue, and mouth ulcers. Iron deficiency can cause fatigue, weakness, and an irregular heartbeat. 

All vegetarians and vegans should get nutrition tests to ensure they're in optimal health. A total iron-binding capacity test and a B vitamin panel test are recommended. 

Weight Watchers Diet 

The weight watchers diet is popular and effective when you stick to it. However, bear in mind that the weight watchers diet is primarily focused on a 'calories in-calories out' approach. 

If you deprive yourself of too much food, you may miss out on essential nutrients, and many people's immune systems' suffer as a result. 

prolonged calorie deficit can cause adverse symptoms. If you have low energy levels, hair loss, constant hunger, and always feel cold — it's time to get a blood test to check you're not causing damage to your body. 

South Beach Diet 

The South Beach diet is a relatively low-carb diet but isn't as strict as Atkins or Keto. In general, it's easier to avoid nutrient deficiencies on this diet as long as you prioritize getting good nutrition. 

However, a full panel screening test is often helpful for people following the South Beach diet as it involves changes to your dietary habits that can lead to several vitamin and mineral deficiencies. 

Mediterranean Diet 

The Mediterranean diet is, as you might expect, based on what's eaten in Mediterranean regions. It's a diet that's high in fruit and veg, but also unsaturated fats and fish. 

This diet is more accepted in the medical community than other diets. However, it does come with cautions. Your risk of vitamin or mineral toxicity is high with this diet as you consume lots of fish and nuts. 

There have been cases of vitamin Avitamin B7, and mercury poisoning from this diet, so make sure you stick to the recommended daily portions. 

Western Diet 

The Western diet is full of ultra-processed foods that are nutritionally bankrupt. If you eat a Western diet like many of us, you should immediately get a complete nutritional panel test. 

Any adverse day-to-day symptoms that you experience (e.g., tiredness, aching muscles, uncontrolled blood sugar levels, and headaches) may come from undiagnosed deficiencies, so do not dismiss your symptoms. 

Gluten-Free Diet 

Whether it's to help manage celiac disease or for other reasons, the gluten-free diet is gaining popularity in the western world. 

However, many foods that are eliminated from the diet when eating gluten-free contain essential nutrients such as folatemagnesiumvitamin B12, and vitamin D

Eating gluten-free can be good for your nutritional status but make sure you get these nutrients from other sources. 

If you experience any gastrointestinal symptoms, skin sensitivities, or unexplained weight gain/loss, consider nutrition tests to evaluate your health

DASH Diet

The DASH diet helps lower blood pressure and reduces the risk of heart disease. It's rich in fruits, vegetables, fruits, and grains. 

This diet is designed to prevent ill-health, so nutritional deficiencies aren't very common on this diet. However, people on DASH should be mindful of getting enough nutrition from their vegetables as they're missing out on a whole host of vitamins and minerals in dairy products (limited on the DASH diet). 

You should check out any adverse symptoms while on the DASH diet with a full nutritional panel to pinpoint the exact cause. 

Frequently Asked Questions 

Between unqualified 'health influencers' and dodgy online sales, it can be challenging to know where to turn for advice about nutrition testing.

It's natural to have questions, and it's good to do your own research before investing in a product. Here are some of the most common FAQs when it comes to nutrition testing. 

How Are Deficiencies Diagnosed? 

Unfortunately, it's very difficult to get a nutritional deficiency diagnosed through your usual healthcare provider.
