negative-calorie foods – the killer diet trend that\u2019s supposed to have everyone losing weight in droves. proponents of these foods claim that the body uses more calories to digest the foods than they supply. the idea is pretty solid when you take some of the lowest-calorie foods into consideration, but the metabolism may not be as strong as you think. can a food actually cause a negative-calorie balance? and, do we know precisely how many calories it takes to digest certain foods?\u00a0<\/span><\/p>\n let\u2019s take a look, first, at what a calorie really is.\u00a0<\/span><\/p>\n a calorie is a unit of measure. specifically, it is the amount of energy it takes to increase a kilogram of water by up to one degree celsius. this may appear to have nothing to do with food but rest assured foods contain calories, and our bodies need those calories to function.\u00a0<\/span><\/p>\n calories were first defined in the late 1800s. the first term to be used related to a calorie was joule. one calorie equals about 4.2 joules. today, the term calorie has taken the throne, and few people even know what a joule is.<\/span><\/p>\n believe it or not – there are two types of calories. one is a calorie and the other a kilocalorie. the calorie is a smaller unit than the one we read on the back of nutrition labels. it takes 1000 calories to make up a single kilocalorie. so, when a serving 10 calories, it actually has 10 kilocalories and 10000 calories.\u00a0<\/span><\/p>\n for the sake of negative-calorie foods, we\u2019ll stick with the traditional term calories for the units in food.\u00a0<\/span><\/p>\n what if you never had to worry about what calories are in what foods again? with the noom free trial offer<\/strong><\/a><\/span>, you are taught how to eat to lose weight and keep it off. the psychology of weight loss and your personal coach are just two of the tools used to help you reach your goal.\u00a0<\/strong><\/span><\/p>\n now, the calories in each food don\u2019t just magically appear when they are picked, prepped, or processed. a machine called a calorimeter was once used to determine the calories in food. \u201cfood was placed in a sealed container surrounded by water – an apparatus known as a bomb calorimeter. the food was completely burned and the resulting rise in water temperature measured.\u201d this measurement was used to determine the total calories in the food.\u00a0<\/span><\/p>\n today, thanks to information provided by the bomb calorimeter, we know that proteins supply about 4 calories, carbohydrates about 4 calories, fats about 9 calories, and alcohol about 7 calories – per gram. when food is labeled, these figures are used to calculate the total calories.<\/span><\/p>\n before getting any deeper into the negative-calorie food debate, let\u2019s take a look at what science has to say about the impact of calories on weight loss.\u00a0<\/span><\/p>\n according to research from 2017 in global health action, treating obesity using a calorie imbalance, such as taking in fewer calories than you burn, \u201cmay not be sufficient to manage and reverse obesity.\u201d so, even if there are negative-calorie foods, will those foods be able to actually to help you lose weight?\u00a0<\/span><\/p>\n also, in 2017, research in perspectives on psychological science shared research with the same results. this time around, not only were calories found to have little impact on overall weight loss, but there\u2019s also a possible connection to weight gain. the study revealed, \u201ca reduction in energy intake is counteracted by mechanisms that reduce metabolic rate and increase calorie intake, ensuring the regaining of lost weight.\u201d<\/span><\/p>\n a simple search for \u2018negative-calorie food\u2019 will return 10s of millions of results. there is no lack of information on the foods that magically cost more calories to digest than they supply. with this theory in mind, eating only negative-calorie foods would result in extreme weight-loss, which could cause severe side effects – over time.\u00a0<\/span><\/p>\n that\u2019s only one part of the debate. there\u2019s also the fact that everyone has a different metabolism, and foods cost a different number of calories to digest for each person. what is a negative-calorie food, loosely used, for one person may not be the same for another.\u00a0<\/span><\/p>\n research from 2014 published in health scope<\/em> showed that, based on a review of all available studies, the negative-calorie diet was no more effective than a traditional low-calorie diet. essentially, the two are the same as both support eating more low-calorie fruits and vegetables.\u00a0<\/span><\/p>\n another bit of research puts the brakes on the negative-calorie debate, or so it seems. based on information from the academy of nutrition and dietetics, only about 10% of total calorie intake is used for the digestive process. there is a slight thermic effect of food that comes with every food eaten, so that\u2019s taken out of the equation. so, if you eat 15 calories of celery, you will burn about 1.5 calories digesting it. that\u2019s far from the total 15 calories you consumed.\u00a0<\/span><\/p>\n there are various types of diets that, based on the rules of the diet, could be considered to be based on negative-calorie foods. before jumping into any of these diets, let\u2019s take a look at the most common negative-calorie foods. all negative-calorie foods are in the fruit and vegetable categories. this is not an all-inclusive list, but it does give a good look into the types of foods that are not supposed to hurt your calorie count.\u00a0<\/span><\/p>\n now, let\u2019s take a look at how these foods fit into diets that typically support the low-calorie options.\u00a0<\/span><\/p>\n raw food diet:<\/strong> a raw food diet exists when a person consumes only foods heated to no hotter than 115 degrees. most foods are consumed raw, thus the name. with raw food diets usually comes a vegetarian or vegan menu. most animal products need to be cooked to a higher temperature than 115 degrees for safety.\u00a0<\/span><\/p>\n you can bet that many of the foods listed above are consumed by people on the raw food diet. however, taking in only raw foods makes it difficult to meet nutrition requirements for overall health. so, you need more to your diet than negative-calorie foods.<\/span><\/p>\n very low-calorie diet:<\/strong> a very-low-calorie diet is one that supplies fewer than 800 to 1000 calories. the menu is typically suggested by a healthcare professional as part of medical weight loss. sometimes meal replacements are used for protein needs, but many of the negative-cal foods are also allowed and recommended. the foods aren\u2019t recommended because they are proven to burn more calories than they supply – they are included because of the strong nutrition profiles.<\/span><\/p>\n liquid diet:<\/strong> a liquid diet is also often prescribed by a healthcare professional. in most cases, the menu consists of meal replacement or protein shakes. some people find a liquid diet more natural to adopt after having weight-loss surgery. fruits and vegetables can be juiced and consumed in natural form, which also, in this case, is encouraged because of the nutrition provided – not because the foods burn calories.<\/span><\/p>\n hcg diet:<\/strong> the final diet that relies heavily on foods, commonly referred to as negative calorie, is the hcg diet. first and foremost, there is no research to prove hcg promotes weight loss. and, hcg is a prescription medication that\u2019s not available in supplement form. now, on to the diet. you are allowed no more than 500 calories a day, and the calories are often consumed in fruit and vegetable forms. the hcg diet is highly restrictive, and the fruits and vegetables are often the only sources of nutrition.\u00a0<\/span><\/p>\n the diets mentioned above are not considered healthy or long-term solutions for weight loss. when you try a program like noom<\/span>, it takes just 10 minutes a day to learn how to eat, how to move, and how to feel better about yourself. check out the free trial offer<\/strong><\/a> today!<\/strong><\/span><\/p>\n jumping back a little bit, let\u2019s take a closer look at the foods that are supposed to be negative calorie and check out the calorie totals for each. here you\u2019ll find the total calories in one serving of each food, the 10% of calories it takes to digest the food, and the net calories supplied to the body.\u00a0<\/span><\/p>\n based on the idea that you only burn 10% of total calories during digestion, none of the foods listed would actually cause a negative-calorie effect.\u00a0<\/span><\/p>\n the thermic effect of food is the total number of calories it takes to digest said food. the percentage varies among people, body weight, health, and even specific food. what\u2019s interesting about negative-calorie foods is that most are carbohydrate heavy. it takes a shorter time to digest carbohydrates than it does protein and fat, which is why the latter of the two help you feel fuller longer after you eat. eating carbohydrate-heavy foods may help you feel full right now, but without some protein and fat, the effect won\u2019t last. eventually, you could be eating more calories in fruits and vegetables than you would if you didn\u2019t focus on negative-calorie foods.\u00a0<\/span><\/p>\n factors that affect the thermic effect of food include:<\/span><\/p>\n research doesn\u2019t say much for the negative-calorie food diet. it appears that eating a diet based on these foods is no more effective than a low-calorie diet. specifically, when comparing the two diets, \u201ccontrary to expectations, both weight-loss diets were equally efficacious,\u201d according to the turkish journal of medical sciences<\/a><\/em>.\u00a0<\/span><\/p>\n there\u2019s also a problem with underestimating the total number of calories in \u201chealthy\u201d foods. when groups of people were asked to decide which of two foods contained fewer calories, they often chose the negative-calorie foods. however, both foods contained the same amount of calories. thus, people who believe healthy foods contain fewer calories may eat more and be consuming more calories than they would have with more traditional meals, says research in plos one.\u00a0<\/a><\/em><\/span><\/p>\n no, you cannot eat unlimited vegetables and lose weight. assuming that you\u2019re consuming some other foods in your diet, there are other calorie sources to take into consideration. following a diet that\u2019s made up of only negative-calorie foods is unsafe and unhealthy. not only will the diet supply too few calories, but essential macronutrients, vitamins, and minerals are missing from many fruits and vegetables. you simply won\u2019t get what you need to stay healthy, and severe side effects could occur.\u00a0\u00a0<\/span><\/p>\n the centers for disease control and prevention<\/a> (cdc) does into great detail on how to add fruits and vegetables to your diet to get the most out of these superfoods, and nothing is mentioned about the foods causing a negative calorie effect.<\/span><\/p>\n an interesting topic that\u2019s come up as of late is the concept of the negative-calorie meal. imagine combining very low-calorie foods with food-based metabolism boosters. could that, in theory, help you burn more calories? believe it or not, the answer is yes.\u00a0<\/span><\/p>\n while there are no negative-calorie foods, some foods do help increase metabolism, so when partnered with these low-cal foods, you could burn more calories.\u00a0<\/span><\/p>\n for instance, steaming broccoli adds no additional calories, so one serving is about 30cals. top that broccoli with some chili peppers or calorie-free hot sauce, and things could get good from there.\u00a0<\/span><\/p>\n chili peppers have been shown to increase metabolism through the body\u2019s reaction to heat. thus, if you eat spicy peppers with your super low-cal food (negative-calorie food), you will burn more calories than if you didn\u2019t.\u00a0<\/span><\/p>\n the proponents of negative-calorie or zero-calorie foods aren\u2019t limited to people on the internet or those trying to sell some programs. there are at least two major weight-loss programs that promote, or have promoted, the idea of zero-calorie foods.\u00a0<\/span><\/p>\n weight watchers (ww): in most versions of ww, there has been some sort of 0-point food list. these foods can be consumed in the amount you like as long as you don\u2019t overeat, and they don\u2019t count toward your point total. points are equivalent to calorie intake with the ww program. there are no foods with no calories, so all foods count.\u00a0<\/span><\/p>\n nutrisystem – nutrisystem is another of the programs that support zero-calorie foods. the numi app, which is the partner app to the nutrisystem food program, doesn\u2019t subtract the calories consumed as part of a predetermined list of foods – many of which are considered negative-calorie foods. we must say again: all foods have calories and all calories on a plan where calories count should be counted.<\/span><\/p>\n one final topic to touch on in negative-calorie foods is the sugar substitute. you can buy everything from baked cookies to sodas or tea that contains some form of sugar substitute. the alternatives claim to have zero calories – so you get the sweetness of sugar without the simple carbs.\u00a0<\/span><\/p>\n the problem with sugar substitutes is that science is up in the air about safety and the effect on appetite.\u00a0<\/span><\/p>\n in one study published in the yale journal of biology and medicine<\/a><\/em> shares that in some people who choose products with artificial sweeteners, weight gain occurs. there appears to be some connection between the sweeteners and an increase in appetite though the effect does not occur in everyone.\u00a0<\/span><\/p>\n another study, this time in current gastroenterology reports<\/a><\/em> says, \u201calthough artificial sweeteners were developed as a sugar substitute to help reduce insulin resistance and obesity, data in both animal models and humans suggest that the effects of artificial sweeteners may contribute to metabolic syndrome and the obesity epidemic.\u201d<\/span><\/p>\nwhat is a calorie?\u00a0<\/span><\/h2>\n
