I keep seeing people say that the Zone Diet is high in fat, so I thought I’d really look into whether this is true or not. Here are my findings. Firstly, what is the recommended fat content for men and women, do you know?
I went to the Institute of Grocery Distribution (ICD) an oddly named body if you ask me but they seem to be the people who publish this kind of information. Having said that, they don’t appear to list the fat information we want freely on their website, the main GDA page here shows no actual values. You can read a short paper about the background to the Guideline Daily Amounts (GDA) from the Scientific Advisory Committee on Nutrition website, which does give the fat GDA amounts. Here’s the table you may be familiar with from food labels:
So for a fella we’re looking at 95g of fat per day and 70g for a woman. Now we need to look at what the Zone Diet specifies. First things first, the Zone Diet can be a bit confusing when it comes to fat blocks. I will one day write a detailed article on why it’s so confusing, but let’s just take a simple approach and say that you need 3g of total fat per block on the Zone Diet eating plan.
For a man, let’s say on 14 blocks per day, that’s 14 x 3 = 42g of fat. For a woman, on say 11 blocks per day, that’s 11 x 3 = 33g of total fat. Let’s see how that compares:
|Diet||Men / 14 blocks
||Women / 12 blocks|
|Comparison||56% less||53% less|
So there you have it, the Zone diet recommends about half the fat than that recommended by the Guideline Daily Amounts that are promoted by the government and appear all over our food labels. The only time this wouldn’t be the case is if you’re eating more than 15 blocks as a man, or more than 12 as a woman. This could be true if you were doing a lot of exercise for example. Either way, that looks like a low fat diet to me!
