Flexitarian Diet & Weight Loss
Have you been considering a plant-based diet, in order to reduce inflammation, reverse insulin resistance, and lose weight?
Are you concerned that you won’t be able to handle eating only plants? Well, the Flexitarian diet might be for you!
I’ve been following it for the past five years. My mobility has increased, dramatically, I have lost weight, and my insulin sensitivity has improved, significantly.
In this post, I’m going to share some weight loss considerations, a few of which may be new to you.
I will also share some practical stuff, like the kinds of basic ingredients I stock in my kitchen, some meal ideas, and a shopping list, to get you started.
What Is The Flexitarian Diet?
In case you’re not familiar with this term, it’s a combination of the words “flexible” and “vegetarian”. The diet was designed by a dietician called D.J. Blatner.
The Flexitarian diet is a way of eating where one focuses on consuming mostly plants, but is still allowed a small amount of animal products, as needed or desired. There is no one right way to do it, but there are certain “levels”.
Some people eat eggs and dairy every day, but only eat meat, on occasion. Some people eat strictly plants, most of the time, but occasionally indulge in some kind of animal-based product. There are many variations, in-between.
My Extreme Weight Loss Journey
My Challenges & Approach
Because I am trying to heal from a spinal condition & periodontal disease (both of which require adequate protein and tissue support), irritated digestive system, insulin resistance, and obesity, my focuses are a little different than the average person who might be taking on or considering the flexitarian diet.
I have been eating flexitarian for the past five years and I’ve tried variations of it (more or less animal products, junkier and cleaner, normal vs. low-carb). So, I have a fair amount of experience with how it affects my body, at least.
My eating plan is currently gluten-free, dairy-free, low-glycemic, anti-inflammatory, high protein, and flexitarian. I typically eat one serving of meat or eggs, per day. About 95% of my diet consists of plants.
Eating Disorder
A little background: I’ve been obese since I was six years old, due to developing a secret binge eating disorder. My family was very toxic and abusive and I turned to candy and whatever else I could gorge, in order to numb the emotional pain. Also, my parents were food addicts, so it’s no wonder I became one, as well.
Active, But Still Obese
I was quite active, as a child. I danced whenever I could, I took aerobics classes, I was on a swim team, I tried softball, I was in marching band throughout high school, I played volleyball, and I walked or biked, whenever I could.
Unfortunately, I never really addressed my eating habits, so I was still obese, despite all of that activity. You know the saying, “You can’t outrun a bad diet”? Yeah. That.
Weight Loss Inspiration
In my late teens (1996-1998), I worked in a clothing store and was studying fashion design at a junior college. I was determined to lose the extra weight and be able to fit into the clothes that I was selling.
In addition to running around a store 15-20 hours, per week, I walked to the gym, then did cardio and weight training, after every shift. I lost a significant amount of weight. I don’t remember how much I weighed, unfortunately, but I do remember that I was able to fit into a size 14/16 and my body looked significantly different. So did my face, LOL. Can we say “chiseled cheekbones”? LOL.
Unfortunately, I hadn’t done the inner work to heal my mind, so I couldn’t deal with the consequences that came with the physical changes. I had zero confidence, I was still very anxious and depressed, and I felt very threatened by all the attention I was getting from men. So, I put the weight right back on.
Many years later, when I came to Colorado, in 2011, I lost sixty pounds dancing and riding a bike all around the area.
Because of my disabilities, plus the very high cost of living, in Colorado, I ended up homeless in 2016 and had to stay at shelters. I was dependent on them for food. Unfortunately, with the upset of being in survival mode, plus eating whatever I could get my hands on (it was mostly carbs), my food addiction became out-of-control, again. I gained the sixty pounds back, plus more.
The Final Straw
In 2017, I weighed in at the doctor’s office and found myself back up the scale at 295 pounds (see pic on the left). I was in pain, all-the-time, and I could barely walk. I also had high blood pressure and I was very concerned about my heart, because I was experiencing random pains and other sensations. Plus, my family has a long history of heart disease and heart failure.
I was approaching 40 and I knew I had to get the weight off (once and for all, gosh darn it!) before menopause started to take root, so I made it my top priority.
Weight Loss Trial and Error
I initially lost 30 pounds with exercise (swimming and walking) and no major diet changes. Then I stalled for a few years, despite my fitness efforts. Note: At the time, I was living in communal housing, with no kitchen access, so I only had so much control over my diet.
I gained control over my food consumption and I lost another 35 pounds with keto. Unfortunately, that really hurt my body (I acquired a knee injury, because it ate at my tissues). I also started to see signs of major inflammation and accelerated aging (zoinks!!). I somehow learned about the correlation between inflammation and weight gain and I started to lean more towards plants.
When I got my apartment in 2019, I was excited to have my own kitchen and I leaned further into the plants. I cut back on my animal food consumption to only a couple servings, per week. Unfortunately, my tissues started to fall apart, I developed anemia, I was dizzy all-the-time, and it was clear that my body was way out-of-balance. So, I had to add more animal products back in.
I’ve lost about 22 pounds, with the flexitarian diet and exercise. I realize that doesn’t sound like a lot, but I also kept off the 65 pounds that I had lost, before, while going through perimenopause, and that’s kind of a big deal. Ten of those pounds came off, when I cut out gluten and dairy. I believe that’s a result of reduced inflammation and glycemic load, plus improved insulin sensitivity.
My Weight Loss Goal
I would love to be able to say that I lost over half of my body weight. I started out at 295 and my goal is 145 pounds. I have lost about 87 pounds (at last weigh-in) and have another 60 or so, to go.
Nutrition
My Knowledge of Nutrition
I have learned a ton about nutrition, over the past five years, because I’ve been trying to figure out how to heal my own body.
I have consulted with a dietician who specializes in diabetes. I have also consulted with a health coach at a local health food store. I have met with three different endocrinologists, regarding insulin resistance, carb restriction, weight loss, bone density, cortisol, perimenopause, etc.
I have scoured the internet for articles and information. I’ve watched many YouTube videos, created by health experts, as well as by those who have lost huge amounts of weight, with various methods. I have used myself as a lab rat, trying many different things, to see what does what.

A Passion for Nutrition
I have a very scientific side and I love a good experiment. Learning about how different foods affect my body has been very exciting. Over the past five years, I’ve found myself naturally gravitating towards many hours of health research. Also, the more that my hands are occupied doing research, the less they’re occupied shoveling food into my mouth, LOL.
I’m not saying that I’m an expert on nutrition and weight loss, but I do have a wealth of knowledge that I feel called to share with you, so that it may make your path easier.
General Weight Loss Factors
Every body is unique and I can’t guarantee that the this approach is going to help you lose weight. But, it can’t hurt to try it, right? Here are some things to consider, regarding weight loss, in general:
Calories
Weight loss is seen as based on calories in and calories out. It’s not quite that simple, because there are other factors involved, like hormones, but getting a calorie deficit is important. Calories can add up far more quickly than you realize. When you’re just starting out, you might want to track how you normally eat, for a couple weeks (www.cronometer.com), and see where you’re at, in terms of calorie intake. Check out this calorie calculator for an idea of what to shoot for. Keep in mind that going too low can impair your metabolism and make you super hungry, so slow and steady wins the race!
Insulin
Our bodies need a certain amount of insulin, to function normally. But too much causes weight gain or the inability to lose weight. I am recommending a low-glycemic diet, which means eating foods that are unlikely to spike your blood sugar and insulin levels. There are many plant foods which can increase insulin sensitivity and help with blood sugar control, which is one of the main reasons to go flexitarian. You can also check out the post that I wrote about how to control your blood sugar with your food choices.
Inflammation
Chronic inflammation can cause weight gain. Overweight is a cause of chronic inflammation. That creates a vicious cycle. The only way to break it is to reduce inflammation. You can do that by removing allergens from your diet & environment, stopping any unhealthy habits, like smoking, limiting animal consumption, eating mostly plants, etc. Even though the flexitarian diet isn’t strictly plants, it is plant-based, so I’ve got you covered on that last one.
Antioxidants
Reducing oxidation is very important with every single meal, according to Dr. Greger, a plant-based nutrition researcher. Additionally, there is a group of antioxidants called anthocyanins that can help with blood sugar control, insulin sensitivity, and weight loss. Have you ever heard the term “eat the rainbow”? Pigments in Mother Nature’s bounty are an indicator of antioxidants. Anthocyanins are found in many black, blue, purple, and some red foods. Check out this article from Healthline, for an overview of anthocyanins. Go here for general info on antioxidants and weight loss.
Cortisol
Cortisol is the hormone that gets released in times of stress. Unfortunately, it raises blood sugar and can cause weight gain. So, getting your cortisol levels down may be a key to losing weight…especially if you suffer from PTSD, like I do, are a bit of a control freak (raises hand), live in clutter and chaos, have social anxiety, or otherwise have a high-stress lifestyle. Going low-carb raises cortisol levels, so I don’t recommend it. You may be wise to get enough of the right kind of carbs & other nutrients, to reduce cortisol and lose weight.
Digestion
Our digestion has so much to do with inflammation, blood sugar, insulin and cortisol production, our microbiome, immune system, and overall health. You can learn more about how our food choices affect our digestion and ultimately our weight, here. You’ll want to focus on slow-burning, whole, unprocessed foods, for the best results. Don’t worry, that’s what I’m outlining, below, because I have to be really careful about digestion, too.
Exercise
A moderate amount of cardio (up to an hour, per day) can help lower blood sugar, insulin and cortisol levels. Exercise burns calories, of course. As long as you don’t eat extra to make up for your fitness efforts and you maintain a calorie-deficit, overall, it can help you lose weight. Retaining muscle is important, too, so you may want to look at doing some resistance exercise. Keep in mind that muscle-building activities can make you extra hungry, so that’s a little tricky for weight loss.
Hydration
Hydration can be very important for weight loss. It makes exercise more effective, stimulates our metabolisms, and more. You don’t want to overdo it, but most people probably don’t get enough water. Maybe track your water intake for a while and see where you’re at? Caffeine should be avoided if you’re trying to lose weight, for a couple of reasons. One of them is that it is a diuretic and can make you shed water. So, limit caffeine whenever possible. Limit alcohol, carbonated, and sugary drinks, as well. Plain water, herbal tea, infused water, soy milk, and nut milks are good plant-based beverage options.
What Not to Eat: Processed Foods
You may already be familiar with most items on this list, and I’m not going to put too much energy into it, right now. But, I feel that these “foods” and additives at least need to be addressed. These are the things that you will probably do best avoiding, or at least limiting, because (my understanding is that) they can cause chronic inflammation and weight gain:
Sugar
Sugar Substitutes
Refined Grains
Bread, Pastries, Pasta
Chips, Crackers
Gluten
Gluten-Free Products
Most Oils
Saturated Fats
Trans Fats
Deli Meats
Red Meat
Conventional Meats
Conventional Dairy
MSG
Artificial Flavors
Artificial Colors
Maltodextrin
Added Starches
Xanthan Gum
Excess Sodium
Hint: Most of these can be avoided by focusing on whole plant foods.
What to Eat: Whole Plant Foods
Now for the good stuff. These foods may not seem very appealing, at first. But, with some time, guidance, and experimentation, you can learn to love them, like I do. These are the foods that make up the bulk of my diet:
Legumes
Beans
Resistant starches help with blood sugar and beans are one of the best sources of them. I always have chickpeas, black, kidney, and white beans at home.
Lentils
To me, lentils are very different from regular beans, which is why I’m separating them out. Hint: red lentils can be used for many things, like wraps, noodles, soups & pizza crust.
Soy
Soy is very unique nutritionally, as well as texturally. I drink two+ servings of soy milk, fortified with calcium, vitamin D, and B12, every day. I also eat tofu & edamame.
Grains
Oats
Gluten-free oats are the only cereal grain that my body really likes. They have a special fiber & resistant starches, both of which can help with blood sugar & insulin levels.
Popcorn
Organic popcorn is a staple, in my house. It’s not too high on the GI and it’s packed with antioxidants, and it’s a whole grain. As long as you don’t overdo it on oil, it can be a filling low-calorie snack.
Vegetables
Leafy Greens
I haven’t always been into kale, but it is so versatile and it’s become my main leafy green, lately. I also eat bok choy (hello, calcium!), spinach, nori & drink matcha.
Vegetables
Non-starchy veggies don’t tend to spike blood sugar & they are nutrient-dense. Some of my faves are olives, mushrooms, green beans & artichokes.
Cruciferous Veg
Cruciferous vegetables are important for overall well-being. I try to eat at least one serving, per day, of red cabbage, broccoli, kale, or cauliflower.
Seasonings
Vinegar
Unless I’m craving something specific, like spicy peanut sauce, I try to stick to low-fat, low-sugar sauces and condiments, like mustard & marinara.
Condiments
Unless I’m craving something specific, like spicy peanut sauce, I try to stick to low-fat, low-sugar sauces and condiments, like mustard & marinara.
Sea Salt
I use sea salt for its mineral content. It does not have much iodine, though, so I have to get that from other sources, like seafood, nori and iodized salt.
Spices
I use a lot of spices! Cinnamon, cloves, ginger, nutmeg, peppercorns, turmeric, cayenne, and so many more can be found in my spice drawer.
Herbs
I use plenty of herbs in my cooking, like basil and garlic. I also use the adaptogens ashwagandha and tulsi for their special balancing properties, i.e. mood support.
Healthy Fats
Nuts
Walnuts are my main go-to nut for their plant-based omega 3’s. I also eat almonds, peanuts, cashews, pecans, hazelnuts, and peanut butter.
Seeds
I don’t eat a ton of seeds, but you’ll usually find chia, flax, and pumpkin seeds in my kitchen, as well as tahini (sesame seed butter).
Avocado
Avocado is one of the fats that I really enjoy. I try to use it whole, when possible, but I do keep avocado oil (regular and spray varieties) on-hand.
Coconut
I eat coconut sparingly, because of the saturated fat content, but I do keep coconut oil (regular & spray), flour, flakes, and milk in my pantry.
Fruits
Lemons
Alkalinity is very important. Lemons are acidic, but they create an alkaline ash in our bodies. I often squeeze lemon juice into my filtered water.
Berries
Berries are in a class of their own, in terms of nutritional value. I enjoy blueberries, strawberries, blackberries, and raspberries.
Apples
Apples are a little higher on the GI, but they’re so nutritious! I try to stick to granny smiths, though I occasionally enjoy a lady alice apple.
Stone Fruits
For a bit of variety, I sometimes eat low-glycemic stone fruits, including peaches, apricots & plums. They are tart, juicy, and delicious!
Beverages
Herbal Tea
I love the flavor of coffee, but it’s acidic & caffeine can spike blood sugar. When I do indulge in a cup of Java, I drink Swiss water processed decaf.
Coffee
I love the flavor of coffee, but it’s acidic & caffeine can spike blood sugar. When I do indulge in a cup of Java, I drink Swiss water processed decaf.
Water
It’s really important to get adequate water for weight-loss purposes and good health. I always have a pitcher of filtered water in my refrigerator.
A Wealth of Plant-Based Options
A lot of things can be made with these ingredients. If you’ve been eating mostly meat, until now, it can take a little while to reorient your thinking. But, you might be surprised that a primarily plant-based diet can open up your palate to more foods and flavor combinations than you ever dreamed possible!
If you tolerate gluten well, that opens up even more options. Though, I advise against eating bread, crackers, pasta, and other processed grain products, if you are trying to lose weight, because they are usually high glycemic. For the best results, try sticking to whole grains, like wheat berries, barley, and rye.
With the basic foods shown above, you can make sides, salads, soups, stews, Buddha bowls, scrambles, skewers, dips, spreads, dressings, sauces, oatmeal, smoothies, and more.
With the addition of a bit of sweetener, like maple syrup, you can also make desserts. Those should be an occasional indulgence (if at all) for the best weight loss results.
Animal Proteins
Bioavailable, But Inflammatory
Animal proteins are concentrated sources of nutrients. They are also more bioavailable to us, than plant proteins, because our bodies don’t have to fight through fiber, to get to the protein. Also certain animal nutrients are just better absorbed, like heme iron. But, animal proteins are pro-inflammatory and can bring negative health consequences. So, many (including myself) believe they should be limited.
Finding a Balance
For health reasons (this was recommended to me by a dietician), I eat one serving of meat or eggs, per day. I usually rotate beef/liver combo, ground beef, ground turkey, chicken, sardines, and wild salmon. I try to eat the meat or eggs at lunchtime, for the best digestion and absorption of nutrients, as well as the least impactive health consequences, otherwise.
Choose Your Animal Products Carefully
Conventional dairy and meat are often produced with the use of genetically modified Monsanto corn (glyphosate) and other pesticide-laden grains. For that reason (and others), you may want to look for the highest quality meats and dairy products, when you do choose to eat them. That means grass-fed and grass-finished, organic, pasture-raised, wild-caught. Or, at the very least, non-GMO.
Dairy Considerations
As I mentioned, I have recently gone dairy-free, due to allergies. However, if you can eat dairy, Greek yogurt and reduced-fat cheese might be a good idea, because of their nutritional value. You might want to consider limiting your dairy intake to once-a-day or less. If you’re concerned about how you’d get enough calcium, by limiting or ditching dairy, you’re in luck! I just published a post on non-dairy calcium food sources.
Dairy & Eggs
Greek Yogurt
If you enjoy yogurt, it is full of nutrients and it might be a good idea to get a serving of low-fat Greek yogurt in, when you’re feeling the need for it.
Cheese
If you tolerate dairy well, low-fat cheese may be a good choice. I’d recommend limiting it to one serving, per day, to keep your saturated fat down.
Eggs
Eggs are very nutritious, but they can also cause inflammation. If I have eggs, it’s usually in place of my serving of meat, for the day.
Meat & Seafood
Red Meat
I use red meat for the B-12, iron, and other nutrients. I’ve been mixing grass-fed ground beef and beef liver to make a delicious and nutritious meat loaf.
Fish
I don’t love fish, but I eat it for the omega-3’s. I usually have canned sardines in my cabinet, as well as wild sockeye salmon portioned out in my freezer.
Poultry
I use ground turkey to make lean sausage crumbles or seasoned taco meat. I usually have a couple different cuts of chicken in my freezer, as well.
Seafood
Seafood is one of the best sources of heme iron. I don’t know about you, but I need some of that, in order to function. Oysters and clams are my go-to’s.
Fats, Inflammation & Weight
Saturated Fat
Saturated fat can cause inflammation, which can perpetuate obesity & overweight. Saturated fat can also raise bad cholesterol levels. So, moderation is the key, here. Meat, dairy, eggs, cocoa butter, coconut products, and palm oil are sources of saturated fat, so you might want to watch your intake of those foods, for the best weight loss results. I was using coconut oil a bit more liberally, until recently, because I thought it was different. However, I’ve noticed a positive difference in my insulin sensitivity, since backing off on it, in the past month.
Oils and Inflammation
Oils can cause inflammation, particularly vegetable oils that are high in omega-6’s and omega-9’s. When I do use oil, I try to use as little as possible, via a coconut oil or avocado oil spray. Look for ones without propellant, if you decide to use them. Oil-free cooking is a thing, if you feel inspired to ditch oil, altogether. You can learn to sauté with water and bake with silicone (silpat) liners or parchment paper, for example. Avoiding oil can change the texture and flavor of foods, but it may be worth it if you’re really trying to get inflammation down.
Fat and Insulin Resistance
Some dietary fat is healthy and necessary. It helps your body to function well and to absorb nutrients. Keep in mind that our brains are made of fat, so it’s also important for cognitive function, memory, and overall brain health. But, an overabundance of fat can perpetuate insulin resistance. I keep my consumption of oils and saturated fats as low as I can and try to keep my overall consumption of fat within a certain range.
Fat and Blood Sugar
Because fat digests very slowly, having some fat with meals can prevent blood sugar spikes. Avocados, nuts, and seeds, in their whole forms, are the best plant-based options. But, there are also plenty of sauces and dips that can be made from them, as well, to add fat, flavor, and interest to your meals, as well as keep your blood sugar from spiking and crashing.
Omega-3’s
Make sure that you’re getting enough omega-3’s, because those are very important. If you eat sardines or salmon, those can be good animal sources. Walnuts, chia seeds, and flax seeds are fair plant-based sources. The body has to work hard to convert those omega-3’s to DHA and EPA, though. That process is very inefficient, from what I understand. I’ve heard that taking an algae oil supplement is a good idea if you don’t eat fish & seafood.
Hydration
Many plants have phytochemicals that lower blood sugar. Additionally, if you back off on saturated fat, that can lower your blood sugar. And, if you reduce your glycemic load, by eating less junk and more whole foods, that can also lower your blood sugar.
Anytime you significantly reduce your blood sugar, you will lose water weight, along with electrolytes. You will have to replenish the lost electrolytes (mainly magnesium and calcium). You may also have to start consuming more sodium, in order to hold onto water and electrolytes. Please check with your doctor, if this is the case. And, it will be important to stay hydrated, without consuming too much water, and washing away the electrolytes you’re trying to hold onto. It’s a bit of a balancing act.
Supplements
I do take supplements, including a multi-vitamin, calcium, magnesium, and zinc combo, Vitamins K2 and D3, reishi mushroom powder, ashwagandha, and tulsi. I take a B-12 supplement and I sometimes take a low dose of iron, if I feel that I need it.
There are certain things you can only get from animal foods (D3 and retinol, for example), which is another reason why the Flexitarian diet is a more balanced way of eating than the vegan diet.
I eat a sheet of nori, every day, which helps with iodine. It also seems to reduce inflammation in my gut and gums, and may be contributing to my weight loss efforts. There can be some concerns about heavy metals and radiation, with seaweed, so please do your own research and see what’s best for you.
Because I am working to build muscle and I want to recover quickly, from my efforts, I drink certain teas. Elderberry tea has a host of health properties and can help with reducing inflammation and post-workout recovery. Green tea and macha can help with all of that. They can also help with weight loss and the removal of heavy metals. That’s significant, because if you start burning fat, that can release heavy metals into your system, which need to be removed.
Resources
It’s going to take me a while to create the kind of resources that I would like to, in order to really get you truly sorted with the flexitarian way of eating. In the meantime, I recommend that you get a copy of the book, The Flexitarian Diet. I also recommend that you read my beginner’s guide on the flexitarian diet.
Beyond that, there aren’t any other sources for the flexitarian approach that I feel good about sending you to. But, there are a few (mostly) whole food plant-based people that I do recommend checking out, especially since the bulk of your diet is going to be plants, anyway. Here they are:
