Do You Have to Be Vegan to Join Lean With Plants?
The honest answer is no, and the reason why says a lot about how the coaching works.
No. You do not have to be vegan to join Lean With Plants. Lean With Plants is a 12-week one-on-one plant-based weight loss coaching program for women founded by Chelsea Mae Cullen, and most clients are already plant-based or want to move that way. They arrive at different points: fully vegan for twenty years, vegetarian, flexitarian, or eating a standard diet and ready for more plants. The coaching meets you where you are and moves you in one direction: toward more plants, in a way that works for your body and your life.
This question comes up on almost every strategy call, usually phrased a little apologetically. So let us take it apart properly.
Plant-based eating and veganism are not the same thing
They overlap on the plate. They are completely different in what they are for.
Veganism is an ethical position. It is a stance about animals, and it extends past food into clothing, products and the rest of life. It is a commitment, and for the people who hold it, it is not negotiable and not about their body at all.
Plant-based eating, in the way we use it, is a nutritional strategy. It is about where your calories come from and how much food you get to eat for those calories. It is a tool for a specific outcome, which for our clients is losing weight without being hungry all day.
Plenty of our clients are both. Plenty are only the second one. Neither is treated as more legitimate than the other.
If you are reading this thinking "I want to lose weight but I am not signing up to a belief system," you are not being difficult. You are being precise, and you are in the right place.
Why a plant-based approach works for weight loss regardless of your beliefs
The reason this way of eating works has nothing to do with ethics. It is arithmetic about food volume.
The concept is calorie density: how many calories are packed into a pound of food.
- Oil is roughly 4,000 calories per pound.
- Non-starchy vegetables are roughly 100 calories per pound.
- That is about a 40x difference.
Your stomach measures volume and weight, not calories. Nobody has ever pushed back from a plate thinking "that was 620 calories, I am satisfied." You feel full when you have physically eaten enough food.
So when the bulk of what you eat sits at the low end of that range, you can eat a genuinely large amount of food, feel full, and still be in a calorie deficit without ever counting one. That is why our clients tend to describe the food as "more than I used to eat," not less. We go deeper in calorie density explained and how to eat bigger meals and still get leaner.
None of that requires you to feel any particular way about animals. It works the same either way.
How clients at different starting points get coached
Here is roughly how it goes depending on where you are when you arrive.
If you eat a standard diet and have never done this before
You are not thrown into the deep end. The first couple of weeks are about assessment and small swaps, not a total overhaul of your kitchen on day one.
Most women in this group are surprised by two things: how much food they are eating, and how fast the cravings quiet down once the calorie-dense stuff is not sitting in the middle of every meal. The beginner's plan covers the shape of this.
If you are vegetarian or eating "mostly plants"
You are closer than you think, and you may be stuck for a very specific reason. Cheese, oil, nuts and convenience foods are the usual culprits, and they are all extremely calorie dense.
Your coaching tends to focus less on adding new foods and more on identifying which three or four items are quietly carrying half your daily calories.
If you are already vegan and not losing weight
This is one of our most common client profiles, and it is the one that frustrates women the most, understandably. You did the hard part. You changed your whole diet. And the scale did not move, or it went the wrong way.
This is exactly what happened to Chelsea Mae. In 2018, at her heaviest after having a baby, she was eating a whole food plant-based diet and still not losing weight. She eventually lost 40 pounds and has kept it off for around seven years, without counting calories. That is the whole origin of the method, and you can read it in her own words on her story.
The usual explanation is the "healthy" calorie-dense foods: oil in everything, nut butter by the spoon, cashew-based sauces, vegan convenience food, dressings, protein bars. Not one of those is bad. They are just dense, and at 4,000 calories per pound, a tablespoon here and there adds up faster than anyone estimates. We wrote about it at length in why some vegans gain weight and the healthy vegan food that is keeping you stuck.
If you are in this group, you do not need to be convinced of the diet. You need the missing variable.
Does the program require you to give up animal products entirely?
Here is the honest version. Lean With Plants is a vegan company. Most of the women we work with are already plant-based or want to move that way, and the habits we teach revolve around it. Chelsea Mae was vegan for over a decade and still stuck, and that is who she designed the program for. We are not going to pretend otherwise or market this as an "eat whatever you want" program, because it is not one.
But you do not have to be all the way there. If you want to eat 80 to 90% plants, this works for you too, and a lot of our clients are in exactly that boat. Either way, we move in the same direction: more plants. More broccoli, less burgers, leaner belly.
Protein comes from plants too, and it is covered in your very first week, so you keep your muscle while you lose weight.
If you are carnivore or keto, this is not for you. That is not a judgment. It is just not what we do.
What we are also not going to do is stand over your shoulder and audit your plate. You are a grown woman. The work is about what the majority of your food looks like, because that is what determines your results. Your coach's job is to help you build a pattern you can sustain, not to grade your moral performance.
Where women land after 12 weeks varies. Some go fully plant-based and stay there because they feel better. Some keep animal products in specific places, at specific times, and build everything else around plants. Both of those can produce the result you came for.
What does not work is treating it as all or nothing, because all or nothing is how most women end up back at the start. Charlene is a good example. She lost 15 pounds in 12 weeks ahead of hip surgery, and the thing she named as the actual change was breaking her all-or-nothing mindset. She said she "finally felt free."
What about your family, your husband, your kids?
The single most common practical objection, ahead of price.
You are not expected to convert your household, and a family that does not eat plant-based is completely normal here. We usually solve it in two ways. First, component meals: you cook one meal and everyone builds their own plate from it, so your kids and your partner have flexibility and you are not cooking twice. Second, filling plant-based meals built for fat loss that even fussy meat eaters do not complain about, most of the time. Your coach works this out with you in week one or two, because it is a logistics problem, not a willpower problem.
And nobody is asking you to announce anything at dinner. A lot of women prefer to just quietly change how they eat and let the results do the talking a few months later.
What if you have tried vegan before and hated it?
Then you probably tried a version of it that was either miserable or ineffective, and possibly both.
The two failure modes we see most often:
- You ate the low-fat, low-flavor version and were hungry, bored and cold for three weeks before giving up. That is a badly built plan, not a personal failure.
- You ate the abundant version with oil, nuts and vegan packaged food and either gained weight or stalled. Also not a personal failure, just calorie density doing what it does.
Neither of those is what the coaching looks like. Beth had tried more than 40 diets before Lean With Plants, which tells you something about how many bad versions of "eat better" are in circulation.
Frequently asked questions
Do you have to be vegan to join Lean With Plants? No. Clients join from standard diets, vegetarian diets and long-term veganism. The program teaches a plant-based way of eating for weight loss, and your coach adapts the starting point to where you actually are.
What is the difference between plant-based and vegan? Veganism is an ethical stance about animals that extends beyond food. Plant-based, as we use it, describes a nutritional approach centered on whole plant foods and low calorie density. You can eat plant-based without being vegan.
I am already vegan and not losing weight. Is this program still for me? Yes, and that is one of our most common client situations. It is usually calorie-dense foods like oil, nuts, nut butters and vegan convenience food rather than anything you are doing wrong.
Will I have to give up cheese, dairy or eggs completely? The coaching is built around plant-based eating and that is what you will learn. Where you land personally is worked out with your coach, and the focus is on the pattern of your eating rather than policing individual items.
Can I do this if my family eats meat? Yes, and most of our clients do. Cooking a flexible base meal and adapting it is normal, and your coach helps you build the system in the first couple of weeks.
Do I have to count calories or weigh my food? No. The entire point of calorie density is that you do not have to. See how to lose weight without counting calories.
