Hi Yvette,
Well done on losing 5lbs.
My first thought is that you’re not drinking enough water. I know that when I first joined the gym I almost fainted a couple of times after my workout as I felt so weak and I suddenly realised it was lack of water.
We get most of the water we need from our food not from what we drink and if you are exercising you need extra water. Try drinking a glass of water immediately prior to your class and another one afterwards and see if it helps.
Hi Yvette,
I just finished my 4th week on the fast diet also and have lost about 4 pounds. I was very tired the first three weeks, especially the day after a fast day. It has started getting better this week.
This is the second time I’ve followed the Fast Diet so I remembered from last time that I would be very tired the day after a fast day so I was better prepared.
Like Amazon said, of course check to make sure you’re hydrating but it could also be that it takes a while for the body to adjust to burning your stored body fat for fuel instead of relying on the food, particularly carbs, that we usually have a constant supply of. But it will adapt! It can take 6 -8 weeks for some people to become efficient at utilizing their stored body fat.
Also, you may need a little extra sleep during the adaptation process. It’s hard work for your body to re-wire it’s energy system so to speak and it’s hard work for it to lose weight. I try to give myself an extra hour of sleep on the nights I’ve had a fast day.
Lastly, it could be that you need to take in a little salt on your fast days. We lose quite a bit when we are hydrating and fasting. For me a cup of bouillon really does the trick. I’ve also just mixed 1/4 teaspoon of sea salt into a glass of water with the juice of half a lemon and in about 20 minutes felt significantly better!
I’ve heard from other people that exercise starts to feel good again around week 5 or 6. I think what you’re experiencing is quite normal! Hang in there! 5 lbs is fantastic!
Hopefully your energy returns soon! I had a very successful fast day yesterday but told my husband before bed last night that I was expecting to feel pretty tired today. I did need an extra hour of sleep this morning but now I feel quite normal and my energy level is great! I think I’m through the worst of it.
Hi Yvette I used to feel tired, lethargic, couldn’t concentrate to the point of not driving ,
and got a lot of headaches on my fast days as I am a migraineur, however this all went away when I changed my fast day to the following:
Begin the first FD meal at dinner, go to bed and don’t eat your 2nd fast day meal till lunch next day. Too easy as I’m asleep during the fast time!
Have healthy afternoon snack
Then have normal dinner( I don’t do carbs at night)
I always have low GI whole grain carbs and high protein in my FD meals as this definitely keeps me going longer
I still eat really healthy on the non FD (no junk food)-but don’t restrict how much.
I found this advise on the 5:2 forum, and it really works well!
Ive lost 5 kilos in 6 weeks
With regards to the exercise, I used to go to the ladies gym or walk 30 minutes on fast days and feel terrible all day after it- but I don’t feel that anymore as I am eating again by lunch time.
Also having healthy snacks that don’t overdo my calorie count helps combating low blood sugar levels during FD.
I actually do 550 cal and sometimes 600 and I still have lost the weight.
I only weigh myself once a fortnight as weight fluctuations occur daily, that can disappoint me if I weigh myself too often.
Hope this helps you work out what’s best for you as everyone responds differently.
Yvette! I’m so glad to hear the salt water helped some and hopeful that the other things will help too. I know what you mean about expecting too much from aging bodies. I’m 51 so you have a year or two on me yet 😉 but i do the same thing.
I’m really excited to be using the 5:2 again because it works so well! I hope you finish with this transition phase soon. I’m sure your energy will be back up in no time!
@annelt….did you say that you fast from lunch to lunch then? And wow! 5 kilos in 6 weeks!?? I usually do dinner to dinner but lunch to lunch might actually be even less distracting. Although, it has definitely gotten easier.
Hello Yvette
I tried intermittent fasting and found it very hard going. I too, felt tired, with tired muscles, despite my efforts to put some energy into my walking. After just a short period of time (perhaps no longer than after two weeks’ 5:2 dieting, I felt that I had low blood sugar, and was amazed at the difference after munching just a small bag of McDonald’s fries. I quickly perked up and the misty vision cleared up. I felt I was back in the land of the living. I could even walk uphill with ease.
Since then, I’ve intermittently fasted by missing breakfast, and sometimes lunch, trying not to overeat by making up for it at dinner
but I can’t say I’ve felt alot better – except on odd occasions when I don’t feel hungry, and don’t feel like eating, or doing much at all when ‘fasting’ doesn’t seem to bother me – otherwise it is a horrible regime. So perhaps it’s better to let your body tell you what it feels like…
Yes, I feel incredibly tired the day after my fasting day.
I’ve been doing the fast diet for 5 years now and I still love it because I can eat almost anything I want on eating days. Fasting days are so habitual that I hardly ever have hunger pangs, at least until I’ve eaten my big 600 calorie meal at 9 PM, then I do get hungry which is why I delay my supper until that late.
The day after fasting day is one of very low energy and I am easily frustrated due to this. I always try to go to bed an hour earlier on fasting days to try to help me to be more energized the next day. Even earlier to bed I have to get up many times to pee and this also kills a good night sleep. This only happens after a fast and I haven’t drunk anything before bedtime.
I come to this forum to seek advice on this day after syndrome. Like I shared with you, I have been doing this 5:2 for more than 5 years. My weight is perfect for me. In the first year I lost 27 pounds and have maintained my ideal weight of 147 lbs. Actually I maintained a weight of 138 lbs .after the first year, but that was 10 lbs. too light.
I have been saying that I need change something about the fasting day in order to feel better the next day because it is becoming too much to bare. Any suggestions are welcomed. Thank you in advance.
I
