I think that, like any diet (or like anything really), it's important to have the discipline not to overdo it (in addition to the discipline to stick with it).

Intermittent fasting can have negative effects, particularly if not done correctly or if undertaken by individuals for whom it is not suitable. Potential negative effects include:
1. **Hunger and Cravings:** Fasting can lead to increased hunger and cravings, which might result in overeating during eating periods.2. **Fatigue and Weakness:** Some people may experience low energy, fatigue, and weakness, especially when starting intermittent fasting.3. **Headaches and Dizziness:** Dehydration and low blood sugar levels can cause headaches and dizziness.4. **Nutrient Deficiency:** Inadequate nutrition can occur if balanced meals are not consumed during eating windows.5. **Irritability and Mood Changes:** Fasting can affect mood and lead to irritability, particularly in the early stages.6. **Digestive Issues:** Changes in eating patterns can lead to digestive problems such as bloating, constipation, or diarrhea.7. **Sleep Disturbances:** Some people might experience difficulties in sleeping, especially if fasting too close to bedtime.
### Who Should Avoid Intermittent Fasting:
1. **Individuals with Eating Disorders:** Those with a history of eating disorders like anorexia or bulimia should avoid fasting due to the risk of triggering unhealthy eating behaviors.2. **Pregnant or Breastfeeding Women:** Adequate nutrition is crucial during pregnancy and breastfeeding, making fasting potentially harmful.3. **Children and Adolescents:** Growing bodies need consistent nutrition, so intermittent fasting is generally not recommended for young people.4. **People with Certain Medical Conditions:** Individuals with diabetes, especially those on insulin, or other chronic conditions should avoid fasting without medical supervision.5. **Underweight Individuals:** Those who are underweight or have a BMI under 18.5 should avoid fasting to prevent further weight loss and malnutrition.6. **Individuals on Certain Medications:** Some medications require consistent food intake for proper absorption or to avoid side effects.7. **Athletes or Highly Active Individuals:** Those with high physical demands may need more consistent nutrient intake to support performance and recovery. 
It's important to consult a healthcare professional before starting intermittent fasting, particularly if there are underlying health concerns.

After fasting when you have the first meal, eventhough you feel like starving to death, you should not consume sweets or snacks first. Vegetables or the food that is high in protein should be the first one.
