As you know, the original hCG protocol is almost entirely fat-free. Added to that and the carbs are pretty carefully controlled. The differences with the Paleo diet would be the use of regular fats, and also a variety of higher carb items like sweet potatoes and sweeteners that are allowed on paleo. Lastly the calories – hCG is typically 500-800 calories. You could follow a paleo diet at that calorie level but with more fat involved, this would be an extremely small amount of food volume-wise because fat has more than twice the calories per gram as carbs or protein – which means that for the same calories, your food is less than half the physical size.
Ultimately, what seems to not work so well is going above a certain number of calories – for most the 500-800 works just fine (and on a good dosage of hCG, many of us actually find we don’t even need all 500 calories some days), some might try as high as 1000 but at this point, in general, your weight loss would definitely be less overall – which may be fine depending on your goals. We do have an excellent interview with a gal who utilized a higher-than-usual calorie amount on hCG with success – definitely check that out.
The higher carb foods and sweeteners Paleo allow I am pretty doubtful would mesh well.
If these were not in the picture and you are left with just the higher fat foods, then we are getting into the keto-adapted style hCG protocols, like hCG 3.0 – there is a facebook group for this protocol which you can find and ask them for more details – from the feedback I’ve gotten it’s worked well for some, and not at all for others.
One thing I wanted to point out though since ketosis was mentioned – it’s a misconception that you must be in ketosis to burn fat, and that you have to show ketones in your urine in order to be in ketosis. Both are not true.
You DO burn fat on the regular Dr. Simeons 500 calorie diet – and you likely will not be in ketosis because of the fruit and total carbs with the layout of the diet. Your body only has 2 things it can burn- fat or muscle. I’ve done my bodyfat testing on this diet and was definitely burning fat even when not showing ketones on the urine strips.
The 2nd misconception is that your body can be in ketosis even though your urine shows no ketones- not always, but if you are eating very few carbs, your body can be in an efficient state of ketosis where your body is actually USING all the ketones it’s generating, so that there is literally none left to pee out in your urine. I believe I got to this point partway through one of my rounds that I was trackin ketone strips.
I hope this helps!
