Which fast should you do to lose weight?

Weight loss is not the result of successful calorie-counting. If it was, we would have solved obesity years ago. Nevertheless many people get caught up in this “calorie in, calorie out” myth, which inevitably leads to frustration and only short term results.

The truth is…weight gain is the result of an imbalance in these two hormones: insulin and leptin. Without fixing these two hormones, weight loss efforts will be fleeting. So how do you fix leptin and insulin? 


Insulin in your fat storing hormone. When insulin isn’t able to manage sugar intake (aka glucose), the body resorts to storing sugar in fat tissue. 

Insulin resistance is created over time. It’s an accumulation of years of inflammation in the body–the result of poor diet and lifestyle. You may have spent years as a “constant snacker”, or addicted to fast foods, harmful oils, bad fats, processed or sugary foods.

Fasting works to stabilize blood sugar. As this happens, the body starts to look for and burn old stores of fat packed away years ago. This is called “fat-burning” mode. 

In order to get this fat-burning mode, you’ll typically need to fast between 15-36 hours.

If you’re new to fasting however, you’ll want to start with mastering intermittent fasting, which entails 13-15 hours of fasting, then increase to 24 hour fasting and once you’re comfortable, you can try a 36 hour fast

If you’ve been fasting consistently and still struggling to lose weight, I highly recommend integrating a weekly 36 hour fast into your fasting lifestyle. This often gives the body just enough of a hormetic stressor–the good kind of stress–to kick it into fat-burning mode.

Leptin is your fat burning hormone. It lives in our fat tissue and tells the brain that you have stored fat available and ready to burn. However if the signaling system between your brain and fat is not working properly, ie. leptin resistance, the body will not move into fat-burning mode. Instead it will stay in sugar-burning mode, leading to weight loss resistance. 

If you’re gaining weight for seemingly no reason despite all your efforts, you may want to look at toxicity. Toxins are known to create insulin and leptin resistance.

This is because the areas of the brain that register leptin are not protected by a blood-brain barrier, which make them vulnerable to toxins. Toxins from heavy metals, plastic, phthalates, mold, etc can actually contribute to leptin resistance by literally blocking the hormone receptor sites on cells

Autophagy fasting can help detox the cells to open those receptor sites up and regain leptin sensitivity. Autophagy fasting entails 17 hours of fasting, breaking your fast with good fats then waiting at least one hour before opening up your eating window.

That being said, if you know toxicity is an issue for you, then you may need a deeper and more thorough detoxification of your cells, which is what I teach in the 90-Day Toxin Reset program.
