I’m only on day two of this diet, yet I’m already experiencing a persistent headache. I’ve tried keto before and recall having the keto flu. But this time, I’m still consuming carbs, so I didn’t expect to have to go through this. Is my body detoxing or something?
I believe it may be typical. I got a minor headache for three days after starting to track calories and eat healthier. My brain was saying “shame on you” lol. Then I adjusted and feel really fantastic

Definitely. Sugar withdrawal is real, and your body will respond if you abruptly quit eating like you used to. This can result in poor energy or headaches for a while.
On the plus side, this is usually just temporary. When your body becomes accustomed to it, you will feel 10 times better than when you were eating poor foods.
To avoid headaches, just make sure you’re not in too much of a deficit and that you receive enough rest, drink, exercise, and time outside.
Could be typical, but make sure your deficit isn’t too high and you’re not “starving” yourself.
It’s difficult to say for certain, but it might be due to detoxification, particularly if you used to eat addictive foods, a shift in your electrolyte balance, or something wholly unrelated to the diet.
Try drinking electrolyte drinks and getting some sugar - it doesn’t have to be much, just a glass of apple juice. It might be a million different things; are you giving up something you would ordinarily rely on? Coffee, Coke, etc.
Of course, eliminating some food groups might result in vitamin and mineral shortages, which can cause headaches.
When you consume insufficient calories or eat an unbalanced diet, your body may experience electrolyte imbalance. This suggests that there are insufficient sodium and potassium levels (especially in this case), resulting in more frequent headaches.
Long periods of fasting or missing meals can lead to hypoglycemia (low blood sugar levels). This disorder may cause headaches, fatigue, and dizziness. You can avoid hypoglycemia by eating small, regular meals. This method will help you lose weight and avoid headaches. Also, include enough protein in your diet to keep you feeling full for longer.
Yes, it can be an indication of both blood sugar abnormalities and dehydration. Many people neglect to drink fluids, primarily water, while fasting. The entire culture shift for IF has everyone drinking tea and coffee to suppress their hunger, despite the fact that this is quite exhausting if you do not drink enough water.
In the fasting condition, your body burns all of the excess glycogen and fat (toxins are stored in the fat cells), so you may be getting rid of some toxic fuel, and what could be better than some light detoxification through fasting - which would also explain the headaches.
Yes, excessive dieting, such as reducing your food intake, might have a negative impact on your brain health. Glucose is the most essential source of nutrition for our brain cells to function properly and remain vital. So, ensure that your diet plan includes all of the important sources of nourishment in the form of a balanced meal. Starving and depriving yourself of a balanced meal free of glucose can result in major consequences. So, take care. I hope this helps!
One reason you may experience headaches while dieting is an alteration in the body’s fluid and mineral balance. This is particularly frequent when salt levels fall too low. To avoid headaches caused by low sodium/salt levels, we recommend supplementing your diet with extra table salt or drinking a cup of prepared bullion twice a day.Fasting, eating high-sugar foods, dieting excessively, and missing meals can all cause or exacerbate headaches and migraines. Even delayed or irregular meals might have an impact. This is frequently caused by people’s blood sugar levels going too low.
When you consume insufficient calories or eat an unbalanced diet, your body may experience electrolyte imbalance. This suggests that there are insufficient sodium and potassium levels (especially in this case), resulting in more frequent headaches. People who get headaches when fasting should drink plenty of fluids between ‘Iftar’ and ‘Sehr’, and at ‘Sehr’, they should eat a high-fat diet to avoid significant protein breakdown after a long fast, according to Dr. Haroon.
Yes, headaches can develop during a diet due to factors such as calorie restriction, blood sugar fluctuations, dehydration, and caffeine withdrawal. To avoid food-related headaches, eat a well-balanced diet, remain hydrated, and manage your stress. Check out my Quora profile for more information on how to manage headaches while dieting.
