What makes Fastify good for intermittent Fasting?

Although one of the attractive aspects of IF is that there is not strict calorie restriction during your eating windows, one of the success factors is selecting foods with the right macro-nutrient content to help avoid becoming unpleasantly hungry during your fasting period.  Fastify is high in protein and fiber and low in sugar to help you feel satisfied and in control.

How does Fastify help reduce food cravings while I’m intermittent fasting?

Fastify is a blend of ingredients that have a low glycemic index.  Foods with a high glycemic index cause a rapid increase in blood sugar levels that is followed by a rapid response by insulin (the hormone that moves glucose from blood into cells) which leads to a rapid return to feeling hungry. Low glycemic index foods help to keep appetite under control. 

How does Fastify help me maintain my energy levels while intermittent fasting?

Calories are measures of energy.  Fastify is designed to be a controlled source of calories that will avoid a spike and then precipitous drop in blood sugar levels.

What is intermittent fasting?

Intermittent fasting is a lifestyle eating program where you cycle between periods of eating and fasting. It is based on how your body best metabolizes food and is more about when you eat and the overall wellness benefits as opposed to counting calories for the sole purpose of losing weight.  There are several different intermittent fasting methods, all of which split the day or week into eating periods and fasting periods.

How do I incorporate Fastify into my 5:2 fast?

On your fasting days, we recommend you use two Fastify pouches and fill the remainder of your calories with other low-sugar foods.

How do I incorporate Fastify into my 16:8 fast?

Let your body tell you when you need Fastify.  You may get the best benefit from enjoying Fastify to start your eating window to settle your appetite and avoid over-consuming unhealthy foods.  Or you may develop the habit of sipping on Fastify during a mid-afternoon slump to avoid the temptation to grab a high-sugar snack.  Or consider a warm bowl of Fastify at the end of the eating window to help you through your fast without constantly thinking about food. You will quickly learn what works best for you.
