These are just a few tips that I have for... Really, anybody. Specifically, those thinking about starting a fruitarian, frugivorous, raw vegan, frugan, vegan, or vegetarian diet!
Greens. My diet does consist of some greens, though ethically I don't feel that this is ideal. Obviously I would prefer to be eating nothing but freely given fruit - however, there are no 100% fruitarians in nature, and minerals tend to be much more abundant in vegetables - so, I believe that for optimal health, one must eat some veggies, the best being delicate leafy greens like lettuce (try to stay away from cruciferous and root veggies, they are harder on digestion). To stay as ethical as possible (if this is your goal) always make sure to only take what you need without killing the plant - for me it is an important difference, between taking what I need and killing.
I don't eat things like seeds, nuts, grains, spouts, and root veggies - as it is necessary to take the life of a plant in order to eat any of these. These are not ideal foods for humans, at any rate, so I advise that everybody stay away from them.
Eating enough. Another important thing is to eat enough! Fresh fruits have high water content, so it will seem like you are eating much more, but you actually won't even be getting ENOUGH calories! At first you will want to make an account on a website like Cron-O-Meter that will track your calories and nutrition daily... Make sure you are getting AT LEAST 2,500 calories every day to fuel a healthy, exciting, adventurous lifestyle!
High carb, low fat! This is the healthiest diet! Try to keep your carbs:protien:fat ratio to 80:10:10. Fresh fruits and veggies will supply this ratio very well, but try not to eat too much avocado or durian. Carbs fuel your body and give you energy and happiness (in addition, carbs never make you fat! Even if you did over eat on carbs...which is all but impossible...the excess carbs would be burned off as excess heat.) Too much fat or protein in your diet will make you feel less than your best, and lead to serious, degenerative diseases like diabetes or colon cancer in the long term. Though they can be enjoyed in moderation, try to keep from eating too much of fatty fruits like avocado and durian.
Stay away from cooked food! Did you know that when you eat cooked food, your body reacts to it as a pathogen? That doesn't sound very healthful, right? It's not! When we cook food, carbohydrates carmellize, proteins denature, and fats carcinogize, producing compounds like acrymalide, which has been proven to cause cancer in mammals. In addition, most other nutrients are destroyed with heat, meaning that you are basically just eating empty calories - no wonder cooked meals leave don't leave you energized and invigorated!
(As a side note, if you must eat cooked foods, try to eat them steamed, as for some reason, studies show that this has the least carcinogenic effect on foods.)
Follow these tips and your diet will provide you with everything you need, in terms of nutrition! If you choose to follow this path, you are about to reach a whole new level of amazing, vibrant health, and you are just going to want to shout it to the world, 'cause its that great. (;
Good luck on your journey, and for sure feel free to leave a comment or send me over an email at firstname.lastname@example.org, I'd love to provide whatever support or guidance you might need.
Or, feel free to just search my blog... I'm pretty sure I have some useful stuff in there (though a lot of it is also outdated, back from when I was eating high-fat.)
Wishing you all peace, love, fruit, and loads of sunshine! ☼
