well, some have more complex carbs... and some have more fat (avocados) and some have protein, but still "plant based diet" usually means complex carbs...
Healthier for sure, but it can't be considered 'low carb diet'
A “low carb” diet doesn’t exclude high amounts of insoluble fiber. It excludes high amounts of carbohydrate calories.
If you are consuming your 2000 calories diet, and it is coming from plants, you are still ingesting 2000 calories worth of carbs.....
1 kg of feathers, and 1 kg of iron, weight the same....
The feathers will be large and take more volume, while the iron will be small and more dense.
Same with foods.... if your plant based diet you are consuming 2000 worth of bio-available calories, then that is still mostly carbs...
It is healthier for sure than consuming 2000 calories through processed foods such a muffins, chips and other crap. But, still your 2000 CALORIES will come through CARBS, but they will be digested slowly due to the fiber.
But if you are ingesting 2000 bio-available calories through plants, it is most likely mostly carbs (plus some fats and protein). Insoluble fiber just goes towards your poop, and it is usually not counted under 'carbs'.
When you say Plant based diet, people assume lettuce, beans, tomatos, carrots, olives, broccoli, etc.. etc...
There are plenty of fats in nuts and legumes, which are compatible with a low carb (even if not a zero carb) diet. Seeds are also rich in fats (and are the source of many vegetable oils).
Most of them (grains, legumes, fruits and nuts to a certain extent) would fall under high carb when eaten in those quantities
For me (and generally I'd say), low carb is <50g of carbs per day.
It's basically not possible.
If you really want to eat a low carb plant based diet, you'd have to eat almost exclusively processed food like olive oil and Seitan.
Potatoes, rice and bananas are whole-food, plant based, and are pretty much the highest carb you can go. And plants without starches and sugars simply don't have many calories at all. You can't survive on broccoli alone.
If you're doing low-carb and getting the calories you need, there's no physically possibly way to get those calories except through protein and fat -- they're literally the only other 2 macronutrients.
So yes, low carb always means lots of meat, cheese and/or fat. Or else you'd basically just be fasting.
Yes, vegetables are less calories dense. That doesn't mean meat/cheese/bacon have to be eaten. Just an easy example, avocado's are extremely calorie dense, and yes this means fat.
The issue I have is that you just categorize meat, cheese and fat together as if the only way to get fat is via those items, or as if fat itself were unhealthy. The second is just a myth, the first is a myth the person you are responding to is directly opposing.
It's not a great surprise that a diet restricting one of the three food macros will lean heavily on the other two groups.
