80/10/10 is a diet devised and popularized by Dr. Doug Graham. In essense, he proposes that a diet made up of at least 80% carbohydrate and no more than 10% fat and 10% protein is optimum for human health. This is not a diet about weight loss, although it can certainly be used to help shed excess weight.
At the same time, by eating enough calories from raw foods, which 80/10/10 is all about, it is also possible to put on weight. In other words, the diet can be used to achieve your health goals, whatever they are. It can help with short term goals such as, increasing your energy levels; mid-term goals, e.g. weight management; as well as long term goals, living a long and healthy life.
The 80/10/10 is obviously a high carb diet. Since it advocates raw foods, fruit is the primary calorie source for people living this lifestyle. Bananas, dates and mangoes are three of the primary fruits. This is because they are fairly high in calories.
What you have to realize, is that to get the calories you need to live your life to the maximum, it takes dedication to actually eat enough if you are only eating fruits and vegetables. It's quite easy to fill up on low calorie fruits. Even though you might feel full, you'd simply not be getting the quantity of calories that your body requires on a daily basis.
Therefore, when starting the 80/10/10 diet, an important point is to actively count your calories. This has nothing to do with being worried about eating too much. It is in fact all about ensuring that you eat enough. So rather than thinking in terms of one banana being a snack.
You have to start thinking that ten bananas are a meal. Indeed, an intersting aspect of 80/10/10 is the idea that we have to train our stomachs to accept more food than they are used to. This is because the typical foods that we eat, animal products, are have a high calorie to mass ratio.
Fruits and vegetables on the other hand, typically have a much lower calorie to mass ratio. So to get the calories we need from fruits and vegetables to live an active life, we have to eat a greater volume than our body is used to. Using a machine such as the Omega VRT350HD might be the best juicer for someone following a high carb raw vegan diet. This juicer can make juice from all kinds of fruits and vegetables.
Juices can themselves be a meal, as long as we drink enough. As an example, two liters or more of freshly squeezed orange juice makes a wonderfully hydrating breakfast. You'd be surprised how difficult it is to eat this amount of juice because it really does fill you up.
