I did like being vegan when I did a week long challenge a few weeks ago, and I now try to incorporate it 3-4 days a week. I feel great have a lot of energy and have been maintaining my weight.
But there's a common misconception out there, that vegans can't get fat. It's true to a certain degree, but it's also false. It all depends on what foods you are eating.
If someone is vegan and they eat a lot of sugary foods, their blood sugar will spike just like anyone else. They will have the same risk of diabetes, etc. Vegans are only truly protected from obesity when they eat a variety of plant-based foods.
Yes, you can eat a lot of kale, but if you are eating a lot of sugary snacks in between meals, you have the same risk as others with bad diets. It's all about clean eating, whether you are vegan, vegetarian, flexitarian, what ever you consider yourself.
I do eat a huge assortment of different foods each day. I have so many different foods to choose from, even when I eat vegan. It's important to get all the proper nutrients and vegans especially can miss vital nutrients like vitamin B12. By eating all the different color vegetables and fruit, along with taking supplements for B12, vegans can be protected from ever worrying about getting fat.
