When you are looking for solutions to help you lose weight, there are some things out there that can point you in the right direction to help you meet your goal but if the research is not done correctly then you could be misled in the wrong direction. Understanding the terminology used like the term negative calorie foods can help clear up any misunderstandings that you might have about the product.
Negative calorie foods refers to items like raw foods that have a minute amount of calories in their raw and natural states where you actually burn more calories digesting and processing and do very little to add calories to your diet. These are basically burned away very quickly. These items are various fruits like apples, oranges, strawberries, etc. vegetables like celery, cauliflower, onions, and broccoli and so on.
Once you understand this then you are able to manage your food intake with more discrimination. But because of the nature of the weight loss business, there are other ways that products misuse the term negative calorie foods to try and sell their products without any evidence to back up their claims such as zero calorie sodas.
Major companies that have tried to sell the same idea through their products failed to be recognized by the fda and ended up in litigation from a watchdog group that forced these companies to repackage their pitch away from the idea that drinking their zero calorie soda as a way to help with weight loss. There is caffeine in the drink for certain that stimulates and boosts metabolism but should not be used as a substitute for health benefits or a diet plan.
When things like this happen it comes to confirm what many have thought all along, that the misuse of the language is a diabolical way to sell more products and it is an angle that works for the company and misdirects the customer. Negative calorie foods should be seen as something that provides the benefits of vitamins and mineral and not on their calorie intake.
