Is the diet simple and practical? This a very important consideration because if it is not, your diet simply will not work. You will not be able to follow it day in and day out. For weight loss this is what is needed. Not a diet that is good for a day, a week or even a month. Though it is possible to lose some weight in just a day, it would not be much and certainly not enough if you have a weight problem. Does the diet include simple exercises that will not stress you out? It should be something easy and one which you can slip into your daily routine. Is the diet well balanced? Does it include the various elements essential for weight loss or is it based on just one? There are many that focus on just one element such as low carb, one type of food or fruit Was the diet designed and developed by dieting and nutritional experts? Is it based on the latest technology, scientific evidence as well as proven dieting techniques? Do not overlook this in your best diet for weight loss checklist. Does the diet or program provide you with one-on-one consultation and or community support at no extra cost? To qualify as the best diet for weight loss, this would indeed be a big criterion. We all differ. No one size fits all. The same goes for a weight loss diet. You must be able, if and when you need, to get some answers to a problem or personal situation. Does the diet offer variety? Is it interesting? Are new additions made as often as possible? Does it use what is current in terms of medical evidence and developments in the field of nutritional technology and strategies? Would you have total control in deciding your daily menu? Would the diet enable you to lose weight and keep it off in the long term? What is the point of losing weight quickly and gaining it back just as quickly? Is the diet affordable? Do you get a money back guarantee? Leave the pre-packaged and celebrity diets to those to whom money is not an issue. You can lose weight and still keep your shirt or dress on.
