You didn’t mention electrolytes, which is a big red flag in the fasting world. So that’s probably the issue. Otherwise, you probably experienced low energy levels, which don’t feel awful per say, but can really bore you.
I’m on day 22 of a 33 day fast, and while the results are beyond anything I could have hoped for, I still have a hard time recommending it. Extended fasting is definitely the hardest method of fasting.
I’d recommend trying a slower, more consistent approach. ADF, 5:2, or OMAD are all great options, and you generally don’t need to take electrolyte supplements on them as long as you make sure to eat electrolyte rich foods.
I’m doing a 10 day water fast right now too I’m on day 7 and yeah if I don’t drink enough water or if I start doing things with lots of physical stress I feel bad my body aches randomly i poop horrible randomly it’s a process to detox the body this is my second 10 day fast and I’ve done 3/5 day fast all the time it’s like getting pass day 6 “shit” gets real with the detox
I was doing for research for my self on how to start and found these ways:
- The 16:8 schedule – on this, you will fast for 16 hours and eat only during the remaining 8 hours. The conventional wisdom is that you eat your first meal at noon and complete your last one by 8 PM. Though, you can choose the actual 16:8 hours to suit your lifestyle and convenience.
- The 5:2 schedule – this refers to days and not hours. So, you eat normally for 5 days of the week and restrict the calories on the other 2 days. During fasting days, women should aim for 500 calories, and men can consume 600 calories. Important: do not fast on consecutive days!
- Eat-stop-eat – this is a stricter and more restricted version of the 5:2. You eat normally for 5 days and fast completely for 2 days of the week. During the 2 fasting days, which should not be consecutive, you eat no solid food but only have no-calorie beverages or water.
- Alternate-day fasting – as the name suggests, you switch to fasting every other day, restricting your diet to 500–600 calories.
- Skipping meals – this is an unstructured version of IF. Two or more times a week, you simply skip a meal. You may not experience a great deal of weight loss on this method, but it’s easier to follow.
- The Warrior diet – this is a diet that only permits you to eat one large meal, preferably in the evening, during a 4-hour window. In the earlier part of the day, you are restricted to eating only small quantities of vegetables and fruit.
So basically, for me works the best 16:8 schedule, but you could try out skipping meals and gradually build your stamina for 16:8 fast?
