Reviewed by Brian St. Pierre, MSc, RD, CSCS<\/a><\/p>\n (Thanks for the joke, Dad.)<\/p>\n But seriously: If you look at the caloric recommendations of many popular weight loss diets, you\u2019ll notice that 1200 Calories is often the \u201cideal target\u201d for women. (For men, it\u2019s often 1500.)<\/p>\n The 1200-Calorie diet is also an extremely popular topic on Reddit, TikTok, and Instagram. Allegedly, even Kim Kardashian followed this prescriptive diet.<\/p>\n There\u2019s nothing special about 1200 Calories specifically.\u00a0<\/em><\/p>\n However, all this hype makes a person\u2014or a concerned coach\u2014wonder about low-calorie diets in general<\/em>.<\/p>\n Most importantly: Is such a low caloric target safe and sustainable?<\/strong><\/p>\n In the following article, we\u2019ll address that question, as well as:<\/p>\n But first\u2026<\/p>\n It\u2019s thought that the 1200-Calorie Diet dates back to 1918, when Lulu Hunt Peters, MD, released a book titled Diet and Health with Key to the Calories.<\/em><\/a><\/p>\n Dr. Peters writes in an entertaining manner, which may be what led to the book\u2019s lasting popularity. In 2005, the book was reprinted digitally, more than 80 years after its initial release and long after Dr. Peters\u2019 death.<\/p>\n For example, within its pages, you\u2019ll find lots of messy stick and circle figures, along with advice to \u201cskip this chapter. It will not interest you in the least.\u201d<\/p>\n Among the book\u2019s prescriptive advice, readers are cautioned against consuming too much animal protein, as it \u201cmakes the disposition more vicious.\u201d For exercise, Dr. Peters encourages women to brush their hair vigorously, \u201cat least 200 double strokes all over the head.\u201d<\/p>\n (Not everything from this book survived the test of time.)<\/p>\n Embedded throughout is encouragement to consume 1200 Calories. (Says the book: \u201cYou will be surprised how much 1200 Calories will be if the food is judiciously selected.\u201d)<\/p>\n Dr. Peters\u2019 thinking\u2014as well as the thinking of today\u2019s 1200-Calorie diet proponents\u2014goes like this:<\/p>\n Thing is, while the arithmetic is straightforward, fat loss is anything but.<\/p>\n Because\u2014quick fact check\u2014not <\/em>all women\u2019s total daily energy expenditure (TDEE) will be 2200 Calories. A woman\u2019s calorie needs will depend on many factors, including her body size, lean mass, age, dieting history, and activity levels.1<\/sup><\/p>\n TDEE might be much higher than 2200 for some women and much lower for others.<\/p>\n In other words, 2200 Calories is an average\u2014and not a universal number that applies to all women.<\/p>\n Very low calorie diets can <\/em>and do <\/em>lead to fat loss\u2014if you stick to them, consistently.<\/p>\n For many women, 1200 represents about half the calories they need to maintain their weight. That\u2019s enough of a deficit to lead to weight loss for most <\/em>people, including folks with thyroid problems.<\/p>\n It can even overcome adaptive thermogenesis<\/strong>\u2014or the \u201cslowing\u201d of the metabolism after an extended period of caloric deficit. (Colloquially, this is what some folks call \u201cthe starvation response.\u201d)<\/p>\n We know about this because of research done almost 80 years ago.<\/p>\n In the mid-1940s, University of Minnesota researchers published a study called \u201cThe Minnesota Starvation Experiment.\u201d<\/p>\n In this study, 36 men voluntarily semi-starved themselves for six months\u2014all in the name of science. The men ate 1570 daily Calories from food carefully portioned by dietitians. The meals added up to half their normal intake.<\/p>\n Interestingly, their basal metabolic rates did drop\u2014by a whopping 40 percent\u2014but it didn\u2019t stop them from losing weight. After six months, every single one of the men had lost about 25 percent of their weight\u2014no exceptions<\/em>. 2, 3<\/sup><\/p>\n Problem is, semi-starvation is brutal.\u00a0<\/strong><\/p>\n The longer you sustain such a severe calorie deficit, the more your biology fights you, turning down metabolism and turning up hunger and cravings.<\/p>\n (Your body wants you to survive the famine!)<\/p>\n As a result, you may find\u2014as the men in the Minnesota starvation study did\u2014food becomes all you talk about, think about, and dream about.<\/p>\n Food preoccupation became so intense for the Minnesota men that they would routinely lick their plates clean after meals, and even rummage through the trash for food scraps between meals.<\/p>\n (Many of these behaviors persisted even after the study ceased. Study alumni reported needing to keep snacks with them at all times, so they would never have to worry about hunger again.)<\/p>\n During sustained caloric deprivation, many other biological chemicals get out of whack, too, leading to more headaches, depression, anxiety, and cold intolerance.<\/p>\n Plus, your ability to concentrate drops, mostly because you can\u2019t focus on anything other than \u201cWHEN\u2019S MY NEXT MEAL???\u201d<\/p>\n At this low calorie amount, it\u2019s also difficult to consume enough food to meet all your nutrient needs, too. So, the risk of malnutrition goes up.<\/p>\n Because of everything we mentioned above, it\u2019s difficult to consume 1200 Calories day after day.<\/p>\n Instead, what usually happens: Folks nail their calorie targets some days, and wildly exceed it on others.<\/p>\n \u201cClients say \u2018I\u2019m eating 1200 or 1300 Calories a day.\u2019 That\u2019s usually true-ish<\/em>,\u201d says Brian St. Pierre, MS, RD, Precision Nutrition\u2019s Director of Nutrition. \u201cThey\u2019re in the ballpark four to five days a week.\u201d<\/p>\n On the other days, however, dieters find themselves drawn to highly indulgent, calorie-dense foods like\u2026<\/p>\n Even if you\u2019re following your regular low-cal diet for most of the day, just one of the above meals can push your daily total well above 3000 Calories.<\/p>\n A so-called cheat day can also add multiple thousands of calories to your weekly total. Yes, you consumed 1200 Calories on many days\u2014but your daily caloric average<\/em> may be north of 1800.<\/p>\n Depending on your body size and activity level, that may mean no\u2014or just very slow\u2014fat loss.<\/p>\n Even if weight loss is <\/em>happening, people\u2019s expectations\u2014especially when they\u2019re acutely miserable eating 1200 Calories 4 or 5 days a week and think weight should be free-falling<\/em> off\u2014can set them up for disappointment.<\/p>\n (Talking to clients who are frustrated with their results despite claiming to eat a low-cal can be a tricky, sensitive conversation. For help, check out the 5 steps outlined here: \u201cHelp! My client\u2019s not losing weight despite claiming to follow a low calorie diet!\u201d)<\/a><\/p>\n We just made very-low-calorie diets sound like the big bad wolf.<\/p>\n But the truth is, they can<\/em> be appropriate for some people like:<\/p>\n \u25ba Small women<\/strong>: Someone who stands 4 feet, 10 inches tall, weighs 110 pounds, and doesn\u2019t exercise might consume 1200 Calories to maintain or lose a small amount of weight.<\/p>\n \u25ba Clients adept at advanced nutrition protocols<\/strong>: \u201cIf you get paid to look a certain way during a specific time frame, you\u2019re often more comfortable with the tradeoffs,\u201d St. Pierre says.<\/p>\n These clients\u2014like weight-classed athletes, figure competitors, or celebrities\u2014tend to use ultra low-calorie diets as a temporary tool.<\/p>\n Along with water weight manipulation (and maybe some spray tanning\/contouring and good lighting) extreme \u201ccuts\u201d can get these clients competition or photo-shoot ready.<\/p>\n After the big day is over, they return to a more sustainable calorie target.<\/p>\n \u25ba Bariatric patients<\/strong>: The 1200 Calorie target might also make sense for someone who needs to lose weight rapidly for health reasons. Dr. Nowzaradan\u2014one of the stars of the TV show \u201cMy 600-Lb. Life\u201d\u2014famously recommends 1200-Calorie diets for his patients.<\/p>\n In this case, the person should undergo the diet under the direction of a medical professional.<\/p>\n<\/p>\n<\/div>\n (There\u2019s lots of misconceptions around low-calorie diets. If you\u2019re interested in understanding how they really <\/em>affect your body, read: Can eating too little damage your metabolism?<\/a>)<\/p>\n One solution to the 1200-Calorie dilemma is counterintuitive: Bump your daily target up to around 1500 Calories, says St. Pierre.<\/p>\n (For men: Go higher, to around 1800, depending on your activity level and body size.)<\/p>\n You might wonder: \u2018If I (or my client) wasn\u2019t losing weight on a 1200-Calorie diet, how could I possibly lose weight by eating\u2026 MORE? Shouldn\u2019t I eat even LESS?\u2019<\/p>\n Here\u2019s why it works: By adding just a few hundred daily calories, you\u2019ll reduce the intense hunger, cravings, fatigue, and food obsessions that make it so difficult to remain consistent.<\/p>\n \u201cIt feels as if you\u2019re eating more because, on most days, you are,\u201d says St. Pierre.<\/p>\n \u201cYet, while you\u2019ll eat more each <\/strong>day<\/em><\/strong> with 1500 Calories, you\u2019ll likely consume less each <\/strong>week<\/em>.\u201d<\/strong>\u00a0<\/strong>The chart below shows how.<\/p>\n (Note: Because no one consumes the exact calorie amount\u2014day after day\u2014we\u2019ve varied the daily calories to make them more realistic.)<\/p>\n
