Can I Lose Weight Fasting 18 Hours a Day?

Intermittent fasting has gained popularity as a weight loss strategy in recent years. One of the most common fasting schedules is the 18:6 fasting schedule, where you fast for 18 hours and have a 6-hour eating window. But can you really lose weight by fasting for 18 hours a day? Let's take a closer look at the benefits and risks associated with this fasting schedule.

What is 18:6 fasting?

18:6 fasting, also known as the 18-hour fast, is a type of intermittent fasting where you restrict your eating to a specific window of time, usually 6 hours, and fast for the remaining 18 hours of the day. During the fasting period, you consume zero or minimal calories, allowing your body to tap into its fat stores for energy.

Benefits of this fasting schedule:

There are several potential benefits associated with the 18:6 fasting schedule:

Promotes weight loss: Fasting for 18 hours can create a calorie deficit, leading to weight loss over time. When your body is in a fasting state, it relies on stored fat for energy, which can help you shed excess pounds.
Supports digestion: Giving your digestive system a break during the fasting period can improve digestion and reduce digestive issues such as bloating and indigestion.
Boosts cognitive function: Some studies suggest that intermittent fasting may improve cognitive function and protect against age-related cognitive decline.
Supports the body's detox systems: Fasting activates the body's natural detoxification processes, helping to eliminate toxins and waste products.
Boosts immune system and reduces inflammation: Intermittent fasting has been shown to reduce inflammation in the body and boost immune function.

Side effects & risks:
