Fast-5, the Five Bite Diet: And the Winner Is…

imageLately, I’d been concentrating on getting back on my game – mentally more than anything.  I felt very thrown off after my last Five Bite Diet effort.  Over the course of two months (on and off), I lost 24 lbs combining Five Bites with Fast-5 .  However, I gained back half of what I lost within a few weeks.  Following that rebound, it was as if my appetite got uncorrected and I was overeating during my window.  When I say overeating, my intake was still not at the level that it was during my pre-fasting days.  Still, I was overeating enough not to be losing weight and in fact gradually gaining.

In an effort to switch things up, I played with two small meals in an extended window but actually gained more.  Coupled with the holidays, I was headed in the wrong direction for weeks.  Not a great feeling.

January was an interesting month. It’s great to be back on track.

Just like anything else in life, when things don’t work out, it’s best to go back to what you know does work.  I’m now back to good ‘ol Fast-5 alone with no restrictions and I’m losing again. I’ve lost 6 pounds this week.  I’m still up a bit (170 lbs, 67 lbs lost) from my lowest in early December after Five Bites (164 lbs, 73 lbs lost), but I’m definitely on my way again.  I’m also feeling much better all the way around in terms of appetite, energy, mood, etc.

I’m not knocking Five-Bites.  I know at least a few people who have had a very positive experience without any of the issues I’ve mentioned.  But in my “study of one,” despite the weight loss, it doesn’t seem the best choice. To summarize, here’s why I prefer Fast-5.

1. The Five Bite Diet had me hungry and irritable.  I don’t experience “hanger” with Fast-5.
2. I lost weight fast on the Five Bite Diet – about 2-5 lbs per week, but there was a rebound effect following my weight loss, and I gained some (although not all) of the weight back just as quickly.  With Fast-5, even when I overate at times (which was rare) I mostly maintained, rather than gained and there was never a gain of more than a few pounds.
3. On the Five Bite Diet I didn’t have much energy.  With Fast-5 I have much more energy throughout my fast, even during exercise.
4. Lastly, the Five Bite Diet is a diet therefore there are some restriction, the most obvious being the very low caloric intake (no more than 500 calories).  There is no limit on what and how much you eat with Fast-5 and your appetite corrects itself automatically in a very short time.
5. There are a few rules to the Five Bite Diet.  There is only one rule to Fast-5 – eat all your calories within five hours.

Again, this was my experience and yours might differ.  I wouldn’t discourage anyone from exploring the Five Bite Diet because, in the end, it did enable me to break a four and a half month plateau and I also kept some of the weight off.  Just keep in mind that every method has it’s pluses and minuses.  Also, like anything else, underlying factors – age, hormones, etc. – can make a difference in your results.


Hi, I'm Mimi and I've lost 70 pounds (so far) through daily intermittent fasting or "scheduled eating." I'm committed to the fasting lifestyle and to making it as easy and fun as possible. (Yes, I said fun!) If you're on the fasting journey with me or if you're contemplating it, you've found the right place for information, tips, and support.

Thanks for talking about how Five Bites affected you. I looked at that diet but felt I wanted the simplest, easiest lifestyle diet to follow. Fast Five seemed to fit the bill and I don’t feel restricted. I want to eat what I want to eat! I’m good about eating lots of vegetables but sometimes I NEED coconut cake! I like being the boss of me and sometimes those other diets make me feel “bossed around.” I’m glad you’re feeling good about your move back to Fast Five and I wish you much success in you next month!

Hi…Thanks for another intelligent share!! Your opinions are very smart based and I enjoy reading what you have to say. I’ve been lurking at 5 bites for a while, but think it’s too restricted for me. I’ve been on Fast 5 since last March and have had only 13 pounds of results. I honestly have to say my windows have been 6 or 7 or sometimes 8 hours and I don’t watch calories at all. I eat lots of veggies and protein. Think my window needs to be 5 or less, I’ve been considering OMAD also. I am 73 and… Read more »

have you ever tried do the 5 bite diet only 2 or 3 times per week? i plateau too doing IF and that was the solution, in my case i add the 5:2 diet to my IF so i only eat 500 calories 2 or 3 days per week but as i read before you dont like count calories so 5 bites diet can work too i guess..
im sorry english it´s my second lenguage

Hi Mimi, I wondered how it’s going now for you. I have been on IF for about 1 year and have lost about 20 lns. And kept it off. Do you still recommend the 5- 5 plan.
