How it works

The Blood Sugar Diet takes an evidence based approach to healthy living — advising lifestyle change based on recent scientific studies

Low carb Med style

There is overwhelming scientific evidence that a low carb Mediterranean-style diet — one rich in vegetables, olive oil, nuts and the occasional glass of wine or bite of dark chocolate — is better for weight loss, blood sugar control and improving cholesterol than going on a low fat diet. That’s why it’s central to the Blood Sugar Diet.

Reduced calories

To improve your blood sugar levels it is important that you reduce the fat that is clogging up your liver and your pancreas and stopping them working properly. The quickest way to do this is to go on an 800 a day low calorie diet, the sort described in the book. The rapid drop in calories will drain the fat from your vital organs. Alternatively the BSD 5:2 intermittent fasting approach involves cutting to 800 calories 2 days a week giving more flexibility.

Move more

When your muscles become infiltrated with fat they stop being able to absorb and use the sugar that is being carried round in your blood. So rather than being burnt as fuel these excess calories are deposited as fat. The fastest way to reverse this problem is to get active. This will also help build muscle and keep your weight down.

What is right for me?

We are all different — and because of this, there are several approaches that can be taken.
