trying the 5.2 diet, not to loose weight but for health benefits, but have reservations on long term effects eg.:
‘When you starve yourself for more than 12 hours, your metabolic rate actually goes down by 40 percent. Your body senses a dietary disaster and quickly goes into storage mode, rather than burning mode’Michael Roizen, MD, Internal Medicine

‘Fasting can cause your body to store fat because when you don’t eat, it perceives that you’re starving. In defense, your body increases its ability to store calories as fat, so fewer calories go further. Unfortunately, once you start eating again, your body is primed to store any excess calories as fat. This “rebound” effect of fasting, or any kind of extreme caloric restriction, is one of the many reasons why a slow, steady approach to weight loss is the most effective one for the long term. There is no fasting or severe calorie restriction in the Weight Watchers approach to weight loss’.Mehmet Oz, MD, Cardiology

Can someone please help with these concerns? Thanks,

Yes it is true your metabolism drops when fasting, but I dont believe in a rebound, yes you put on some weight when you start eating again but that is mainly your glycogen is replaced.
You know our metabolism changes a lot depending on whether we are working, sleeping. eating or cold or warm, the best way to speed up your metabolism is by exercise.

Have you read the fast diet book?

There is plenty of evidence in it that fasting for short periods of time does not permanently lower metabolism.
As Stuart says, exercise is important. Regular exercise can increase metabolism depending on how much you do, and if you exercise in a fasted state it can be more effective in helping to lose weight as the body has to take energy it requires from stored fat.

Weight Watchers is based on long term day in day out calorie restriction, often promoting “diet” foods and low fat alternatives which are full of sugar and other undesirable ingredients that are needed to replace the flavour lacking due to the removal of fat. WW does not help people to change their eating habits and statistics show that the majority of people who follow WW put all of the weight lost back on once they stop dieting.

In my experience following 5:2 has helped me to lose weight easily without feeling depressed at the thought of yet another day of dieting, and has helped me to change my eating habits for the better. I feel fitter than I have done for years, and my high blood pressure has reduced considerably.
If you look at some of the threads on this website, you will see that there are scores of people who are slimmer, fitter, healthier and most importantly, happier due to following this plan which basically puts the individual back in control of looking after their body properly.

There is enough research to proof that Roizen is completely wrong. Short term fasting actually increases the BMR and is not a disaster at all. It might be worthwhile to see Roizen and Oz for what they are: entertainment and advertising for their own products. They are certainly not a source of unbiased information.

When you look at Michael’s posts here in the forum, he has already covered this subject.

Yea. From Michael, in case someone sees this post and is concerned.
Will it put me into ‘starvation mode’?
‘This is another very common myth. The initial response of your body to a reduction in calories is to increase your metabolic rate. This is because, in our hunter-gatherer past, survival in times of food shortage would have depended on our becoming more active, going out to hunt and look for food. Only under conditions of extreme calorie deprivation, when we have been for weeks without enough food and our body fat has fallen dramatically does the body go into “starvation mode”. IF is not the same as crash dieting. Starvation mode does not happen if you cut your calories for a day!!’

Well said Dummerchen. I wouldn’t be in a rush to consult either of them anytime.
