While fasting, it is important to refrain from consuming any food or drink that contains calories. However, there are some foods and beverages that you can consume while still preserving the benefits of fasting. Here are some foods and drinks you can have while fasting:

• Water: Plain or carbonated water contains no calories and will keep you hydrated during a fast.
• Coffee and tea: These should be consumed without any added sugar, cream, or milk. Black coffee and unsweetened tea are the best beverages to sip while fasting.
• Healthy fats: Some people drink coffee containing MCT oil, ghee, coconut oil, or butter during their fast. Oil breaks a fast, but it won’t break ketosis and can tide you over between meals.
• Bone broth: This rich source of nutrients can help replenish electrolytes lost during long periods of only drinking water.
• Soups: Soups that contain protein and easily digestible carbs, such as lentils, tofu, or pasta, can gently break a fast. Avoid soups made with heavy cream or a large amount of high-fiber, raw vegetables.
• Vegetables: Cooked, soft, starchy vegetables like potatoes can be good food options when breaking a fast.
• Fruits: Whole fruits like berries, apples, and bananas can be consumed in moderation during a fast.
• Lean protein: Poultry, fish, nuts, seeds, and legumes like lentils and peas can be consumed during a fast.

It is important to note that any food or drink containing calories will technically break your fast. Therefore, it is recommended to consume these foods and drinks in moderation and only during your eating window.
