The continuing thread for those of us following 5:2 or other forms of fasting such as 4:3, ADF, or daily 16:8.
The 5:2 diet was featured on BBC Horizon in August 2012 and essentially requires you to fast for 2 non-consecutive days per week. The other 5 days, you can eat normally - or approximately your Total Daily Energy Expenditure ( TDEE - see explanation below).
4:3 is similar, except you fast on 3 days in the week.
ADF (Alternate-day fasting) is just how it sounds; you fast every other day.
16:8 is another form where you stick to only eating in an 8 hour window each day, therefore fasting for 16 hours each day.
By "fasting", we mean that we keep our calorie consumption very low; around 500 calories on average for a woman, 600 for a man, on fast days.
You'll find on these threads we use a number of acronyms. If you're new to the threads, or Mumsnet in general, they might not make much sense.
WOE/WOL = Way Of Eating/Way Of Life. We use this term instead of "diet" as many of us see this as something to do in the long term.
MFP = My Fitness Pal, a website or app many use for keeping track of the number of calories they're eating.
TDEE = Total Daily Energy Expenditure, quantifies the number of calories you burn in a day. This measure is best estimated by scaling your Basal Metabolic Rate to your level of activity. TDEE is critical in tailoring your nutrition plan to desired fitness goals. Here is a link to a TDEE calculator to help you figure out how many calories you should be eating in a day.
FD = Fast Day
NFD = Non-Fast Day
NSV/LSV = Non scale victory/Lifestyle (change) victory

This is a BBC article regarding Michael Mosley's findings, which was featured on Horizon - link to that programme here.
This Telegraph article comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting.
This blog post gives some of the scientific explanation for why this way of eating helps you to not only lose weight, but improve your all-around health.
This link nicely demonstrates that there are many body ‘right’ body shapes and types, because what we are actually aiming for is low body fat for fitness and health.
A study discussed here gives commentary specifically addressing the effect of this diet on obese people (both men and women), with regard to both health and weight loss. ("After 8 weeks of treatment, participants had an average 12.5 lbs reduction in body weight and a 4cm decrease in waist circumference. Total fat mass declined by about 12 lbs while lean body mass remained relatively constant. It also mentions "Plasma adiponectin, a protein hormone that is elevated in obesity and associated with heart disease, dropped by 30%. As did LDL cholesterol (25%) and triglycerides (32%).")
If you’ve been researching IF you may have come across this article which is highly negative about women with BMI in the normal range. Here’s our response to that:
- With a healthy BMI, those who want to be leaner will usually find weight and waist loss to be much slower than for overweight folk, since less fat and inches are available to lose.
- The women with healthy BMI already had healthier blood sugar than the men in the study. Hence nothing really needed improving.
- Women exercisers who reported health problems on IF were NOT doing 5:2, but the
much tougher ADF or 16:8, combined with heavy lifting (often multiples of body weight)
AND
were often starting from already ultra-low BF 12-16% range.^
-Many were already missing periods or had EDs before IF, due to the low BF %, over-training and over-stressing.
5:2 is a gentler form of IF than ADF or Leangains and there’s plenty of anecdotal evidence from longterm 5:2ers, now with healthy BMI, who are continuing to have very positive results and experiences on this WOE.
A BIG THANK YOU to all who have been contributing. Most of us are learning this way of eating as we go along. All of the links above have been posted by others in our previous threads, and they've been very helpful.
A HUGE THANK YOU to Greeneggsandnicht for putting together all this info and resources into one concise OP text, much appreciated by so many 5:2ers!
Come join us, and tell us about your experiences with this way of life!
And lastly, a few FAQs/Healthy tips :
- WATER: Start each day with a pint of water; and drink plenty during the day.
- HOT DRINKS: No limits on tea or coffee any day, just count any milk / sugar calories on FDs.
- FDs: Concentrate on protein & veg; avoid / reduce starchy carbs & sugar, including juice. Soups & stews are good; ready meals are fine. Old hands skip breakfast & save most cals for supper.
- NFDs: No rules, but to improve health, try to cut down on added sugar, artificial sweeteners, fizzy drinks, junk food. A few treats per week are good though! Aim to average TDEE over NFDs each week, but you may under-eat by say 20% on 3 NFDs to save calories for weekend.
- CLENCH for health: Men & women should exercise pelvic floor daily.
- BFers: start with 1000-cal FDs; optionally, reduce to 700 cals gradually. You can return to 1000 if growth spurts or sleep-deprivation require more fuel.
- SLEEP: Everybody needs enough sleep, or it may slow weight loss.
- EXERCISE: is healthy & can help weight loss if you do NOT eat back exercise calories. Fasted training can burn more fat. HIIT works well with 5:2/IF.
- Do NOT fast: if pregnant, under 21, over-stressed, have EDs, severe anxiety, any illness, even a bad cold. When ill, your body usually needs more nutrients and less stress. So don't force yourself to eat, but if hungry then eat nutritious food to TDEE & cut out junk, added sugar, fizzy drinks.
- CHECK with your Doctor: if you have diabetes, any other endocrine condition, or if taking ANY prescribed medication (fasting may affect absorption rate)
Really trying to but def not lovin' it!!
I'm sure the odd cake is not the reason for your plateau
