Can Vegetarians Get Into Ketosis

Can Vegetarians Get Into Ketosis?

By Nabanita Dutt

One of the main concerns people have when they consider going on a Vegetarian Keto diet for weight loss is this: can Vegetarians get into Ketosis at all?

The short answer is yes, they absolutely can. And not just that. Vegetarians can be almost as successful in burning fat at a very rapid rate on a Ketogenic diet as non-Vegetarians.

But they have to do it right.

The real reason why the majority of Vegetarians fail to achieve Ketosis on a plant-based Keto diet is they have not been educated on the basic strategy they need to `trick’ their body into a state of Ketosis. 

And unless they can truly understand this proven, science-backed strategy and make it the foundational building block of their diet plan, no amount of superficial-level tips, tricks and advice on the internet, or Keto Vegetarian recipes for that matter, can help them be successful.

In this article, we’re going to share this foundational strategy for Vegetarians and Vegans that will finally get you into Ketosis, and teach you how to maintain it for the long-term, for sustained weight loss.

So, keep reading because all the information we present here will not only help you understand Ketosis and avoid all the common Keto mistakes, but the well-proven science of Vegetarianism that will be a valuable health and wellness resource for you for the rest of your life.

Let’s start…

What Is Ketosis?


Ketosis is a natural metabolic state that occurs when your body doesn’t have enough carbohydrates to burn for energy. 

The human body primarily uses glucose, which it derives by breaking down carbs, to make energy. But if the carb supply is cut off for some reason (during a Keto diet, for example), the body has no choice but to break down its secondary resource – stored fat – into ketones and use that for energy instead. 

This, in a nutshell, is the process that is known as Ketosis.

As the body uses up its fat stores, we start losing weight, which is why triggering Ketosis is considered to be one of the fastest ways to slim down on any diet plan.


Why Is It So Difficult For Vegetarians To Get Into Ketosis?


The answer to this question is a very interesting one, and goes back to the early days of human history, when people were mostly rudimentary crop cultivators or cave-dwelling hunter gatherers.  

For these early people, there was no surety about when their next meal would come. Long periods of starvation caused by famines, floods and other natural events were commonplace and the human body simply had to adjust to deprivation in order to survive.

In such circumstances, holding onto fat, quite logically, became the body’s best defense strategy against starvation and death. It used up whatever food source was available at the time to make energy, but was reluctant to dip into its precious fat store, which could prove to be life-saving in an emergency situation.

This compulsion became a part of our cellular memory, and like many other involuntary human responses that have carried over from the past, holding onto fat is just the body’s way of ensuring we stay alive, no matter that food is plentiful these days and we are unlikely to starve.

Attaining the fat-burning state of Ketosis can be hard for just this reason. When we’re trying to go against a reflex body behavior that is deeply ingrained, it is only by triggering a false sense of emergency (by restricting carbs) that we can trick our bodies into starting to burn fat.


4 Things Vegetarians Must Do In Order To Get Into Ketosis


As we said earlier, we have a strategy for Vegetarians to get into Ketosis. But in order to be successful, this strategy has to be followed correctly to stop the body’s default behavior from kicking in and slowing down your fat loss rate.

Read the infographic below for a quick overview, before moving forward.

# 1: Understand The Importance Of `Complete’ Proteins 


‘Complete’ proteins are foods that offer the full spectrum of 9 essential amino acids which the body cannot produce on its own, and therefore has to source from what we eat.

These 9 amino acids are the essential building blocks of muscles. The more muscles you have, the more fat and calories you will burn, but that’s not all. In the absence of carbs, these amino acids also help stop the body from cannibalizing its own muscle mass instead of fat stores to make energy.

Animal-based foods like meat, fish and eggs are complete proteins and have all 9 amino acids. Unfortunately for Vegetarians, plant-based foods are not.

So it is necessary to eat the right mix of plant-based proteins (like soy, quinoa and buckwheat) to make up for the shortfall. 

Choose a variety of high protein, Vegetarian foods as part of your daily diet to make sure you are getting the full spectrum of all 9 amino acids that are necessary for Ketosis.


# 2: You May Not Be Eating As Much Protein As You Think


Another problem with plant protein is that it is not as digestible or bioavailable as animal protein. Not by a long shot. 

A very common Keto mistake that Vegetarians make is this: even if you think you are eating enough protein to get you into Ketosis, much of that protein is not being absorbed by the body and therefore being wasted.

Given the limited bioavailability of plant-based proteins, the best way to ensure you’ll get into Ketosis is to increase the amount of protein you consume per day.

The chart below should give you some helpful guidelines on how much protein to consume by height:

  • Under 5’4″ : 105g for men and 90g for women.
  • 5’4″ to 5’7″ : 110g for men and 100g for women.
  • 5’8″ to 5’10” : 120g for men and 110g for women.
  • 5’11” to 6’2″ : 130g for men and 120g for women.
  • Over 6’2″ : 140g for men and 130g for women.

Now, it is really hard to exactly measure the bioavailability of most foods. The best resource we have is a grading system known as PDCAAS (Protein Digestibility Corrected Amino Acid Score) that gives you the most telling clues.

The chart below should be very helpful in illustrating this.

# 3: Be Wary Of `Hidden’ Carbs


It is common knowledge by now that most Vegetarians depend heavily on high-carb foods. This dependence is hard to avoid when your options are limited to plant-based ingredients only, so it is no surprise if your normal diet has always consisted of wheat flour, rice and corn for example, and tasty veggies like potatoes and peas.

The first thing Vegetarians do when they start on a Keto diet is cut out the obvious carbs. But there is still more…

Even foods that are known to be nutrient-rich and good for health can have `hidden’ carbs. Like lentils and nuts.

Being mindful of this when you’re calculating your daily macros is very necessary because if you’re not taking these hidden carbohydrates into account, your math will be off, you’ll consume way more carbs than 20g-50g per day (depending on your plan), and find it really difficult to get into Ketosis.


# 4: Don’t Take Meat Substitutes At Face Value


Meat substitutes, or mock meats are nothing new. In fact, the practice of `faking’ meat was popular centuries ago among Buddhist monks who would make fake roast goose, fake duck etc. with things like wheat gluten, tofu and mushrooms to help meat-eating disciples transition to a Vegetarian / vegan way of life with minimal discomfort.

Those fake meats were made with natural, plant-based ingredients. The worry with the shelves full of Vegetarian / vegan burgers, hotdogs and other meat substitutes we see at grocery stores these days is that they are highly processed, with additives that may not hold up too well upon close scrutiny.

The purpose is mainly to mimic the texture and mouthfeel of real meat. The presence of highly absorbable proteins and other nutrients is not the driving factor.

This is very important to know when you’re tempted to choose more meat substitute products for your daily diet than is suitable to get into a state of Ketosis.


16 Vegetarian Foods You Should Eat To Get Into Ketosis


1. Eggs

If eggs are allowed in the kind of Vegetarian diet you follow, then they are one of the best sources of complete protein for you. Low in carbs, but high in healthy fats and protein, eggs will help you feel satiated and promote Ketogenesis.

16. Nutritional Supplements


Given the restrictions of a Vegan or Vegetarian diet, it is important to be aware that you may not be getting the full spectrum of nutrients you need to get into Ketosis from your food alone.

In such circumstances, the intake of the right supplements becomes very important for Ketogenic health and well being.

Here are 6 supplements that you should consider: Taurine, Omega-3 fatty acids, Creatine, MCT Oil, Carnosine and B Vitamins like thiamine, niacin and B12.

How Intermittent Fasting Can Help Vegetarians Get Into Ketosis

In order to enter a state of Ketosis, the body needs to be in a carb deficit. This means that you need to be consuming fewer carbs and calories than you are burning. When in a calorie deficit, the body will begin to break down stored body fat for energy.

Intermittent fasting can help to create a calorie deficit in a few different ways. First, when you fast, you are naturally consuming fewer calories. Second, fasting can help to increase your metabolism, which can lead to more calories being burned.

There are a few different intermittent fasting schedules that you can follow. 

The most popular is the 16/8 method, which involves fasting for 16 hours and eating during an 8-hour window. This schedule is often easiest for people to follow, as it doesn’t require any major changes to your eating patterns.

Another option is the 5:2 method, which involves eating normally for 5 days of the week and restricting your calories to 500-600 on two days of the week. 

This method can be more difficult to follow, as it requires a bit more planning and effort.

If you’re interested in trying intermittent fasting to get into Ketosis, be sure to talk to your doctor first. This eating pattern may not be right for everyone. Also, once you start, be sure to listen to your body and make adjustments as needed.
