Testing out intermittent fasting!


Quote  |  Reply

Hi,

Long time reader, first time poster here :)

After doing a lot of research, I've decided to try out the intermittent fasting for the month of March for weight loss AND health reasons.

My plan is as follows;

Day 1: Eat what I normally eat (within my 1700 cals)

Day 2: Cut out morning yogurt with oats (water instead), and my nut intake, which would result in a lower calorie day.

Day 3: Eat my normal breakfast, and then only water and black coffee for the rest of the day.

And those three days on repeat for the month of March.

My stats are:

187 lbs, 5'9 Female aged 23. I am very active at the gym, tennis, swimming. Haven't weighed in for a while so probably weigh less than that but will let you know by Sunday afternoon as I will probably be near a scale Sunday morning.

Before the criticism starts, I have fasted before with absolute ease and even enjoyment. I've also spoken to a professional about it who says it is fine to let your body rest from digestion for a short period of time. I know that every third day might seem extreme, but let's see how it unfolds.

I will let you guys know how it progresses, if anyone cares haha! But I think it would be great to share my experience and get some feedback as there are some majorly smart people on here. 

All comments and suggestions not only welcome but highly encouraged!

How is your exercise schedule going to fit into this? I workout fasted, but it takes some getting used to.

Yes it does take some getting used to..

The quality of my workout immediately following a fast day is horrible. I get disappointed in myself over how bad it was.  I had to stop running to walk 30% faster than my run just 3 days earlier. My body was screaming at me and I felt like crap afterwards until my body loaded back up on calories.  Unless you are stronger than I am and wouldn't be disappointed in the decrease production of your workouts I do not recommend this plan.   

I fast every friday during Lent for religious reasons and my Sat morning runs suffer very bad.  The only friday I will not be fasting is March 16th because I have a 7k race on March 17th.

Oh yes this really does work!

Only if you eat mostly healthily on non fast days too - otherwise you will feel horrendous.. I learnt the hard way!

I have done it only 1 day a week a few times and really felt it revved up my metabolism. Will definitely keep doing it - but will only increase frequency if I plateau.

hope it works well for you, keep us posted and all the best!

sorry for asking on day 2 no breakfast only or no food intake at all??

I'm on that plan now. Well, I use a variation of it called lean gains. I've lost over 10 pounds in 3 months on this life style with a -30% on rest days and +10% on workout days. I also make sure I eat low carb/high fat on rest days and high carb/low fat on workout days. I love this program, and it seems sustainable to me.

Good luck! I'm doing zig zag calorie counting, kinda similar but I don't think I'd survive no food all day! Let us know how it goes! :)
Hmmm this is interesting. Somebody give me another example, please. Or an example of zig zag calories! Since I don't have much to lose I seem to be going sooooo slow. Would love to rev it up some :-)

ZigZag calories.  If you eat 1500 calories, Try eating 1200 calories one day and 1800 calories the next.  It averages the same as 1500 but your body gets a little confused.  I would do this only after eating 1500 calories and then plateauing.  I recommend starting at the 1500 calories (just an example) and then switching to zig-zag calories for a few weeks before switching back to 1500 calories.  Consider it similar to P90X muscle confusion except for your metabolism.  (At least that is the theory)

Heres a link to help calculate your zig zag calorie intake. :)

Good luck!  I've found that I'll do the zig-zagging if I've binged the night before.  Last week, I drank on Monday night and in order to make up for it I fasted for most of the next day.  Paid off surprisingly as I didn't gain any weight that week, and still managed to lose a little bit.

That's the only time I'll do it though, because like others have said...I feel like my strength takes a hit if I fast...so it effects my workouts.  I have a hard time staying consistant and working out hard.

If you do the meal skipper diet don't skip breakfast. And eat LOTS of carbs cuz fat makes you fat.

Unless you do starvation Atkins and induce the diabetics worst nightmare ketosis. If you do this carry glucose tabs in case of coma.

Day 2 I do eat breakfast, but just skipping yogurt with my oats (I'll make them with boiled water), and my morning nut dose.

It is a form of zig-zagging albeit a hardcore one. I'll see how the first 3-day bunch goes, and if I do suffer physically, mentally, and in the gym, I'll reassess. 

Regarding exercise, I'll try go straight after breakfast on my "fast" day and maybe do a quick cardio warm-up and just do some weights and stretching. I normally do a 15 min jog warm-up, about 30 mins on various weights, and then finish with 30 minutes of interval walk-sprint on the treadmill. I love intervals in all aspects of life apparently Innocent.

I will def keep you guys posted. Today's Day 1, but as it's my normal day I'm not too freaked.

Just fyi, you are very misinformed about low carb diets. Fat does not make you fat. There are tons of studies that show that people on high fat diets actually lose more weight and are healthier than people on low fat diets. Fat only makes you fat if you are eating a lot of carbs AND a lot of fat. This is because your body has an adequate supply of carbs to burn for energy and can store the fat. If you are not eating carbs, your body has to burn the fat to survive.

And I'm not sure why you think Atkins is a starvation diet. You can eat as many calories as you want on Atkins, as long as you limit your carbs to whatever stage you are in calls for. I lost weight on Atkins eating 1500-1800 calories per day with minimal activity.

Also, you are getting ketosis confused with ketoacidosis. They are very different. See the information below:

"A lot of people are confused by the term "ketosis." You may read that it is a "dangerous state" for the body, and it does sound abnormal to be "in ketosis." But ketosis merely means that our bodies are using fat for energy. Ketones (also called ketone bodies) are molecules generated during fat metabolism, whether from the fat in the guacamole you just ate or fat you were carrying around your middle. When our bodies are breaking down fat for energy, most of the it gets converted more or less directly to ATP. (Remember high school biology? This is the "energy molecule.") But ketones are also produced as part of the process. When people eat less carbohydrate, their bodies turn to fat for energy, so it makes sense that more ketones are generated. A dangerous condition called ketoacidosis can develop in those with type 1 diabetes, and it is sometimes confused with normal ketosis. The body usually avoids this state by producing insulin, but people with type 1 diabetes are unable to produce insulin. Even most people with type 2 diabetes who inject insulin usually produce enough insulin of their own to prevent ketoacidosis."

I was hoping so, but I have seen some other posts by this person that say basically the same thing.

Every fish'll bite if ya got good bait.

It's only half a joke though. Recidivism is high for low carb dieters. I believe this is due to the fact that 1/2 a molecule of glucose will react with 3 molecules of fatty acid to form adipose triglyceride fat. So if you load your bloodstream with lipids, relatively small reintro of carbs causes regain. The way to avoid the problem is to lose weight on a diet containing fat and carbs together, and go into maintenance on that diet. Read the Wing and Phelan papers and you'll find that the highest long term success in keeping weight off is from low fat. You can lose it any way you like, but why not start out and stay with the proven winner? Bouncing the macros and meal timing around is a good way to establish a lifetime yo-yo pattern.

When I say starvation Atkins, I mean the original low calorie no carbs induction phase designed to send you into ketosis and run on fat. Some people believe that you should continue the induction phase indefinitely and live in a keto state. I mentioned the glucose tabs because diabetics carry them to get out of ketosis, which in the diabetic state can occur involuntarily and with bad results. Oral glucose counteracts this quickly.

If you have a reference for your "information" it would be helpful, but I usually read things like this in pro-keto literature.

The diabetic literature is a little fuzzier on the distinction, but both center around insulin resistance:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2 528854/

If you're not insulin resistant it's not as much of a concern, but if you are and haven't had it diagnosed you could be in for a rough ride. When I was obese I had probably been diabetic for months without knowing it. An Atkins induction inducing ketosis could very well have slid beyond, into ketoacidosis. The syndromes are not as neatly divided as the LC literature indicates.

I just googled it and clicked on the first link: http://lowcarbdiets.about.com/od/faq/f/whatis ketosis.htm

I agree with a few of your points, but I still do not agree that eating fat makes you fat. I have actually become a lot more lean since following a low carb high fat diet. With that said, I do not follow Atkins per se. I eat a lot of fruits and veggies and the very occassional 100% whole grain item (like sprouted, flourless bread). I keep my carb intake at 50g-75g per day rather than 20g like in induction, and this is very sustainable for me. I can definitely see myself eating like this for the rest of my life so I don't have to worry about regaining the weight. And I am not overweight or insulin resistant, so I don't have to worry about ketoacidosis. Different things work for different people and this works well for me. I feel a lot healthier, have more energy, and have greater concentration since I began eating this way. Grains and added sugars make me feel bloated, lethargic, and sluggish.

See the parallel thread on low carb or low fat caitlin. Saying that fat doesn't make you fat just gives encouragement to fat cookie and chip eaters. The high calorie density of junk foods comes in large part from cheap vegetable fats, which makes them much more rewarding to eat.
