All the articles ive read though with women losing their periods they seem to be on very low calories i.e 500 calories..please guide me in the right direction as i love to learn but dont want to fudge up my body as id like to start trying for a baby in the very near future. Thank you
If you are planning to try for a baby and you've heard that this method of eating (not a guarantee that you'll lose weight) could derail that, I would firmly advise against it. Especially the most extreme part of your plan. Talk to your OB and do more homework.3 -
I just drink ... anything without calories, so black Coffee, diet drinks, water, herbal, black and green teas ... dont bother with bcaa's .. thats for 20/4 and 18/6
You actually don't need to bother with bcaa's at all if you're getting enough protein for the day. But, if someone feels that they help and can afford supplementing it constantly, then go ahead and use them.0 -
what are bcaa's?0

A highly hyped rip-off that don't do anything beneficial for you as long as you're getting adequate protein intake (which you should be):

I'm not a gal, but I have read about several women reporting that IF helped straighten out their hormones and that they started having a period after not having one for a long time. It might help.2 -

I would think you should be fine as long as you are at 1450 calories. 500 calories is what caused the women losing their periods most likely.0 -
I supplemented with the BCAA's today and it helped me...I increased my workout intensity, so I need them.3

Thank you for this informational thread. I'm looking more into IF and which IF schedule best fits my own.0

Well im on my 3rd week of IF and excercising at home with full body hardcore workouts. Im on the 18 hour fast and im finding it very difficult..the hunger pangs are so strong. Unfortunately haven't lost any weight apart from a couple of inches off legs and arms:/0

Then don't IF.
If you are engaging in "hardcore workouts" I don't see the benefit of doing them in a fasted state. Especially if they're making you hungry enough to overeat your calories during your feeding window, or if you're eating to the point of uncomfortability.
Exercise is basically fasting in fast forward, so any fasting you've done prior to working out is going to compound onto itself. This is probably not psychologically healthy either considering that it becomes dangerously close to a binge/purge cycle.
Be reasonable and if it's not working, simply stop doing it and go back to something you can manage. If you're trying to rush fat loss, starving yourself and overtraining aren't great long-term strategies.8 -

Any supplement with the word "energy" in it is going to have caffeine or caffeine components to decrease fatigue. If you get enough protein from normal meals then BCAAs become unnecessary. They're pricey for what you can get with a normal diet, but if you can afford it and you feel that they help, then more power to you.

Note the editor footnote from Examine.com stating that the anti-fatiguing effects are probably only noticeable in untrained / newer trained individuals. For people that have more experience, training fasted is completely subjective and it's a thing that must be adapted to. In other words, it's not wise to force fasted training or intermittent fasting in someone that is suffering in performance and it's spilling over into discomfort from hunger pangs.5 -

I run 3xweek up to 6-miles after fasting for 20-hrs. I will bonk if I don't eat something before. I usually eat about 1/2 tsp of coconut oil (100kcal) and I can put in a 1000kcal run and not bonk. The oil feeds the brain (the liver is out of glycogen and not feeding the brain enough and the muscles can't share glycogen with the brain-the brain runs well of the butyrates the oil provides) and then allows the body to use the stored glycogen in the muscles to fuel the workout. The oil does not give me an upset stomach even if eaten just a few minutes before running and it doesn't not cause me to be hungry either. I also use that if I'm having a rough day and can't fully fast the 20-hrs. 1/2 tsp of coconut oil will kill the hunger for a couple of hours for me. Works every time for me! I was worried eating the oil but my triglicerides are at very good levels (71). A little bit of cornstarch 30-min before a run will accomplish the same things and only 100kcal of that will allow me to go from a 400kcal run to a 1000kcal run without bonking. Cornstarch is a slow release carb used in the treatment of people with some forms of glycogen storage disorder. It allows them to sleep at night without having to eat and prevents them from going hypoglycemic (see UCAN superstarch or glycosade which is even a slower release form of cornstarch but more expensive).
You can workout fasted and I've gotten in hundreds of workouts fasted without having a problem doing what I described. You can take some coconut oil (supplies butyrates) and/or corn starch (provides glucose) and be well fueled after a long fast and not have any stomach problems or hunger problems from doing so.2 -
I've done IF 16-8 pretty regularly since Sept without any supplements, just black coffee in the a.m. Slowly getting leaner, faster, stronger, and it doesn't affect my workouts to be fasted. I eat pretty clean and am a vegan. I feel great! Just for general fitness, I'm not training for anything specific or competing.1

I can workout doing 16:8 without problems but for a 20:4 or later, I start having problems if I don't take something.1 -

Fatty acids are perfectly adept for fueling aerobic and endurance training such as the subjects in the FASTER study by Jeff Volek (http://www.vespapower.com/the-emerging-science-on-fat-adaptation/), so coconut oil containing medium chain triglycerides work well for acting like carbs in the sense that by go directly to the portal vein during digestion (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4878196/).
Just to clarify, my statement was meant to dissuade people from forcing themselves to train fasted if they're not acclimated to it. I have no problems training fasted or fed, it just depends on the activity. General strength training focusing on compound and isolation movements can be done in a fasted state. Glycolytic demanding activity, like Olympic weightlifting, I do require being in a fed state to perform, otherwise I risk dropping hundreds of pounds on me. It's subjective, but that is my personal experience.3 -
Question: If I ate during my fasting window and it was my last meal, do I fast 16 hours after that last meal? Should I have drank coffee instead?
Eating window is from 10am-6pm. I was so hungry at 9pm and decided to eat to get some protein in. I started working out close to 12midnight.0 -

You can either adjust your feeding/fasting window from your last meal or just continue as normal the next day. It's not a hard rule. Or you can readjust your entire feeding window to something like 12pm - 8pm, but generally sleep is included with the fasting window, so if you're working out close to midnight, make time for adjusting your schedule based on your sleep patterns.2 -
I have been transitioning into a 16:8 style of IF now for the past 4 weeks. I started with 12:12, 14:10, and have been able to practice 16:8 5 out of 7 days over the last two weeks. I've always been a breakfast eater and tend to hangry if I go too long without food. Nevertheless the idea of skipping breakfast in order to have more calories available to me for dinner, and maybe room for dessert was very appealing. Since I went into it slowly, I have found it to be easier then I thought it would be. And, I have found that I can go much longer than I thought I could without eating before I go into that hangry phase. Initially, I was going 16-17 hours without any problems aside from a little manageable hunger. Since I am so new to this, I have a few questions. I have been having hypoglycemic symptoms over the last 4-5 days for some reason before I get to my first meal at 12. Meaning light headed, poor concentration, and hungry feeling. Now for a background, I have experienced this occasionally throughout my whole life if I go too long without food. But it's kind of random. Also, I have had my fasting blood glucose tested, and has come back just fine. Anyways, I've been sucking on a hard candy to get that light headed feeling to go away until I eat lunch. So, before my 1st actual meal, I have my coffee with sugar free creamer (about 45 cals.) and one jolly rancher(25 cals.) if needed to sustain me till lunch. Will this negate any of the supposed benefits of IF? And, will my body get used to this new feeding schedule and quit sending me those "Feed me. NOW" signals? I posed this question in the IF group and was met with some advice that made my Woo-Dar start going off and was honestly a little over my head. So what do ya'll over here think? lol. Also, my calorie goal is 1420. I typically eat net between 1410-1800 cals in a day.1

I agree with you that it's not wise to force fasted training or intermittent fasting in someone that is suffering in performance and it's spilling over into discomfort from hunger pangs. I would say eat some good food!
I take the BCAA's for extra AA's and because I have to stay totally away from carbs and sugars, due to an inherited condition I have with not being able to tolerate carbs/sugars in my system. I suggested this for her as some extra protein for working out....but more needs to be done in the nourishing, timing, and balancing with diet, fasting, and exercise. It is quite a balancing act.4 -
I just lost another 2 lbs. today, for a total of 29 lbs. with 6 more to go....IF has helped me in many ways to control my intake. It is quite a balancing act though, that has me tweaking it as my daily life activities change.0

The fast is how long you don't eat between meals. I'm not sure of your schedule but it might be easier to fast from noon tell about 8 and workout after you eat if you have somewhat of a traditional schedule.1 -

My weight lifting ability goes way down if I don't eat something before it. The brain will just not allow it if fasted too long. I lift after I eat dinner.1 -

Do most of you eat low carb or keto during your eating phase? Or just count calories? I would like to lose 40#, have started to skip breakfast, but not watching much what I eat rest of day. Thanks!0

I set a calorie limit for the day and try to get up to that point within my eating phase. I also count my macros and try to get in the most for protein and healthy fats. I don't care much for carbs. I also want to lose 40 lbs and stay within my healthy weight.
I don't say I'm skipping breakfast when my eating window is between 12pm-8pm because you can start breakfast whenever you start your eating phase.
Also be aware of what foods you eating during your eating phase. You'll feel healthier and have more energy when you decide to grab a lettuce-wrap sandwich instead of a low-calorie cheeseburger instead for instance.
Good luck and have a healthy lifestyle!1 -
