Topic LOW CALORIE DIETS:This is from a reliable scientific journal that is used for research and information in my nursing school:::: we are all aware of fad diets, whether its been ourselves, our friends or family members who have embarked on them. Usually touted by celebrities as ways to lose weight quickly, these diets often involve cutting out major food groups in order to shed the pounds. But there have been concerns about the impact these can have on peoples health. There is also the inevitable fact that once you start to fall back into your old habits after depriving yourself for so long, you are likely to put the weight back on. Examples include the Paleo diet (based on the principle that we should eat the way we did back in the Paleolithic era - if a caveman wouldnt have eaten it, neither should we); the 5:2 diet (eat normally for five days and fast for two, cutting down your calorie intake to just a quarter of the usual daily amount); and the Dukan diet (four different phases, each concentrating on separate food types). Ceri Perkins, a registered dietitian and founder of One Life Health Wales, said it was important people understood the drawbacks of such diets. She said: First of all, I think that people want quick results when it comes to weight-loss and they may go on quite strict and severe diets. What I would say about a lot of these is that they are not sustainable over a long period of time. People tend to lose weight but immediately when they start eating normally again, they put on the weight. It will lead to disappointment and then further failure. They will often exclude whole food groups, such as carbohydrates, and by doing that they remove essen-tial vitamins and minerals from their diet, which can lead to malnutrition. Celebrity diets do not work. It comes down to healthy eating, which works and is sustainable, and youll lose weight gradually, which means you are more likely to keep it off. Eating a healthy and balanced diet prevents the loss of macro-nutrients such as protein and carbohydrates. Then it also keeps micronutrients so that you do not become malnutritioned. There are lots of common mistakes that people make. They believe in superfoods when there no such things. There is no one fruit or vegetable or seed or grain that is superior. All these foods are super because they bring vital nutrients. Ms Perkins warned that cutting out whole food groups could be detrimental to health. She said: Cutting out certain food groups is not good. Cutting out carbohydrates for a long time will lower energy levels. You body will manage on fat and protein for its energy sources, but it cannot do that for a long time without feeling tired and over time there will be deficiencies. Some of the problems with things like fasting diets is that the person may not eat for days but then they will over-eat on the days they can eat and then they have not accomplished anything at all. The average woman who is able to do 150 minutes of physical activity a week should be eating around 1,900 calories a day. If you are not doing physical activity but are still consuming high levels of calories, then you are likely to be overweight or obese. Having three meals a day with healthy snacks is advisable. A lot of people miss breakfast but this is a big problem as not eating breakfast will mean that you have a period of fasting, which means you require an energy intake and a lot of people will opt for something high in sugar. If you have something that is high in fibre that makes you feel full for breakfast so that carbohydrates are released slowly, you will not have the tendency to binge or over-eat at midmorning or lunchtime.
