More specifically, white kidney beans.  These are the medium sized white beans usually labelled just "white beans" you can buy by the pound or kilo in bulk, or in bags from the grocer.  It's generally more economical to buy in bulk, partly because you can look at them to check for freshness.  White beans will last for months in a sealed container, but you'll need to make sure whoever you buy them from in bulk has a pretty fast turnover.

 

How they help you to lose weight is because their chemistry blocks the enzyme alpha Amalase, that helps to break down carbohydrates to convert them into caloric energy.  This is probably something the plant adapted in order to prevent spoilage due to the carbohydrates in its own seeds, the beans.  If beans didn't have them, they would probably not last very long, so what enables us to dry and store them happens to also be what helps us to lose weight.

 

 

The human body is neither adapted to eat large amounts of vegetable fat, nor is it programmed to limit the amount of vegetable fat it receives.  The reason why is likely because we are supposed to eat vegetables without a limit except actual fullness, so our body doesn't regulate intake at all.  The problem is though, that the vegetable fat is supposed to come with the vegetable.  When it doesn't, more than about 1/5 of a teaspoon in generally low fat vegetables, or more than 1/2 teaspoon in fatty vegetables in one serving, is too much.  In my and others' experience, the only vegetable fat that triggers satiety with similar amounts to animal fats is palm or palm kernel oil.

 

Animal fat on the other hand, triggers satiety when you've had enough calories.  So generally, the fat of choice in my recipies is animal fat, unless it would somehow detract from the taste.  It takes awhile of not eating "junk fat" (hydrogenated vegetable oils) for your system to reset itself, but not very long.  It takes most people around 6 months, but stay with it.

 

 

Raisins are one of the least expensive sources of natural sugar there is.  Bonus, they have iron, vitamin A, a nice cocktail of antioxidants, and are a natural appetite suppressant.  Grapes and raisins are a better superfood than acai berries, and don't lose their good properties from being kept in the fridge for awhile.

 

Other dried fruits with positive benefits, but that are more expensive, are dates and dried cranberries and gooseberries.

 

 

Aside of being a good non caloric sweetener, it also helps to balance your blood sugar.  Whether you're diabetic or hypoglycemic, it's good for you.  In a sweet dish wherein you'll be using some natural sugar anyway, adding a bit of stevia is a good way to supplement seamlessly.
