4:1 Keto Hummus

What is 4:1 Hummus? It’s a keto ratio-recipe (and keto diet used for therapeutic purposes) where for every four grams of fat there is one gram of protein plus carbs (i.e. 80-percent fat by weight in grams). It’s also totally hummus-like and creamy-delicious! From The New Mediterranean Diet Cookbook by Martina Slajerova, Dr. Nicholas Norwitz, Thomas DeLauer, and Rohan Kashid, it’s a real winner that you’ll want to make again and again.
“The 4 parts fat to 1 part protein plus carbs diet is an extra-fatty ketogenic diet used to treat neurological disorders. This ‘hummus’ was contributed by Dr. Chris Palmer, a Harvard psychiatrist and the world’s leading expert on using ketogenic diets for mental health. Dr. Palmer says, ‘The 4:1 diet can be difficult to follow, but delicious recipes like this one make it easier. Keep a batch of this spread on hand in your fridge: it’s delicious on anything. Its versatility is what makes it such a powerful medical treatment!’”

    This hummus was amazing!!! I didn’t know whether I should peel the zucchini or not but left the skin on. I also added some extra garlic cloves. It is sooooo good!! I also added some red pepper flakes for spice. Mine turned out green maybe because of the skin. I will definitely be making this again.

    A HUGE hit!!!

    Had not eaten hummus since I started keto almost a year ago. Made this recipe for a dinner party yesterday and hands down was voted “best in show” even by the non-keto folks. DELICIOUS!!!

    Definitely adding to my “go to” keto recipes!
