There is no scientific evidence to support the claim that any specific fast can help with conception.
Fasting is a practice that involves abstaining from food and sometimes drink for a period of time. It is often done for religious or spiritual reasons, or as part of a weight loss program.
While fasting may have some health benefits, there is no evidence that it can improve fertility. In fact, some types of fasting can actually be harmful to your health, especially if you are trying to conceive.
If you are concerned about your fertility, it is best to speak to a doctor or a fertility specialist. They can help you understand the factors that may be affecting your ability to conceive and recommend a personalized plan for improving your chances of getting pregnant.
