1. Not Drinking Enough Water

When using Intermittent Fasting, insulin levels naturally start to decrease.(1) This natural reduction in insulin can cause the body to release water and promote a state of dehydration. Dehydration, aside from leading to issues such as fatigue and headaches, can also cause an increase in sugar cravings and likely lead to consumption of sugary foods that work against weight loss goals.

2. Jumping In Too Hard Too Fast

If the eating window or meals are not addressed before diving into Intermittent Fasting, this can result in some serious sugar cravings. This process is discussed in more detail with the video below.



3. Not Getting Enough Electrolytes

Along with water, electrolytes tend to get lost in the process of fasting as well. This can increase cravings for starchy, salty foods, such as potato chips or popcorn. These highly starchy foods can cause a massive spike in the storing hormone insulin and work against weight loss goals. Utilizing Celtic Sea Salt or a high quality electrolyte replacement during the fasted state can help to balance electrolyte levels.

4. Not Eating Enough During The Eating Window

A persistent state of semi-starvation (aka calorie restriction) by simply not eating enough during the eating window can lead to decreased metabolism and make achieving a weight loss goal much more difficult. Eating the proper amounts of protein and fat for your body's needs is crucial to prevent this.

5. Using A High Carb Diet With Intermittent Fasting

Higher carbohydrate intake can lead to a higher secretion of the storing hormone insulin and make weight loss (particularly fat loss) an uphill battle. Instead, try using meals focused on stabilizing blood glucose levels and boosting satiety, such as those in the Complete Intermittent Fasting Bundle Meal Plans.

6. Breaking The Fast With A Small Meal

This circles back to the issue of not eating enough during the eating window, which can lead to a variety of concerns ranging from decreased metabolism to increased sugar cravings. Instead, try making one of my favorite, satiating break-fast smoothie recipes like THIS one.


7. Using Collagen During The Fast

Collagen is made up of amino acids and amino acids can stimulate an insulin response. This will therefore break a fast. Instead, keep any collagen supplements during your eating window so that there isn't a risk of breaking a fast.
