If Jerry Seinfeld had been into well being and health he’d ask, “What’s the cope with the 1200-Calorie weight loss program?”
(Thanks for the joke, Dad.)
However severely: Should you have a look at the caloric suggestions of many widespread weight reduction diets, you’ll discover that 1200 Energy is usually the “perfect goal” for ladies. (For males, it’s typically 1500.)
The 1200-Calorie weight loss program can be a particularly widespread matter on Reddit, TikTok, and Instagram. Allegedly, even Kim Kardashian adopted this prescriptive weight loss program.
There’s nothing particular about 1200 Energy particularly.
Nevertheless, all this hype makes an individual—or a involved coach—surprise about low-calorie diets typically.
Most significantly: Is such a low caloric goal protected and sustainable?
Within the following article, we’ll deal with that query, in addition to:
- Why some individuals don’t drop extra pounds on 1200–Calorie diets. (Trace: It has nothing to do with their thyroid or metabolic adaptation.)
- The day by day calorie goal that tends to stimulate weight reduction—and never insufferable cravings or deprivation.
- 4 science-supported methods that assist regulate urge for food and starvation—so people can comply with their meals plan for the long run.
However first…
The place did the 1200-Calorie weight loss program come from, anyway??
It’s thought that the 1200-Calorie Weight loss plan dates again to 1918, when Lulu Hunt Peters, MD, launched a ebook titled Weight loss plan and Well being with Key to the Energy.
Dr. Peters writes in an entertaining method, which can be what led to the ebook’s lasting reputation. In 2005, the ebook was reprinted digitally, greater than 80 years after its preliminary launch and lengthy after Dr. Peters’ demise.
For instance, inside its pages, you’ll discover a lot of messy stick and circle figures, together with recommendation to “skip this chapter. It is not going to curiosity you within the least.”
Among the many ebook’s prescriptive recommendation, readers are cautioned in opposition to consuming an excessive amount of animal protein, because it “makes the disposition extra vicious.” For train, Dr. Peters encourages ladies to brush their hair vigorously, “a minimum of 200 double strokes everywhere in the head.”
(Not all the pieces from this ebook survived the take a look at of time.)
Embedded all through is encouragement to eat 1200 Energy. (Says the ebook: “You may be shocked how a lot 1200 Energy might be if the meals is judiciously chosen.”)
Dr. Peters’ considering—in addition to the considering of right now’s 1200-Calorie weight loss program proponents—goes like this:
- Most girls want about 2200 day by day Energy to take care of their weight.
- A pound of fats accommodates 3500 Energy.
- Should you eat 1000 fewer day by day Energy than you want, you’ll lose about two kilos of fats every week. (As a result of math.)
Factor is, whereas the arithmetic is easy, fats loss is something however.
As a result of—fast truth examine—not all ladies’s complete day by day vitality expenditure (TDEE) might be 2200 Energy. A lady’s calorie wants will rely on many elements, together with her physique measurement, lean mass, age, weight-reduction plan historical past, and exercise ranges.1
TDEE could be a lot larger than 2200 for some ladies and far decrease for others.
In different phrases, 2200 Energy is a mean—and never a common quantity that applies to all ladies.
Why some individuals don’t drop extra pounds on a 1200-Calorie weight loss program
Very low calorie diets can and do result in fats loss—for those who keep on with them, constantly.
For a lot of ladies, 1200 represents about half the energy they should preserve their weight. That’s sufficient of a deficit to result in weight reduction for most individuals, together with people with thyroid issues.
It may possibly even overcome adaptive thermogenesis—or the “slowing” of the metabolism after an prolonged interval of caloric deficit. (Colloquially, that is what some people name “the hunger response.”)
We learn about this due to analysis carried out nearly 80 years in the past.
How your physique fights again in opposition to the 1200-Calorie weight loss program
Within the mid-Nineteen Forties, College of Minnesota researchers revealed a research known as “The Minnesota Hunger Experiment.”
On this research, 36 males voluntarily semi-starved themselves for six months—all within the title of science. The lads ate 1570 day by day Energy from meals fastidiously portioned by dietitians. The meals added as much as half their regular consumption.
Apparently, their basal metabolic charges did drop—by a whopping 40 %—but it surely didn’t cease them from shedding weight. After six months, each single one of many males had misplaced about 25 % of their weight—no exceptions. 2, 3
Drawback is, semi-starvation is brutal.
The longer you maintain such a extreme calorie deficit, the extra your biology fights you, turning down metabolism and turning up starvation and cravings.
(Your physique desires you to outlive the famine!)
Consequently, chances are you’ll discover—as the boys within the Minnesota hunger research did—meals turns into all you discuss, take into consideration, and dream about.
Meals preoccupation grew to become so intense for the Minnesota males that they would normally lick their plates clear after meals, and even rummage via the trash for meals scraps between meals.
(Many of those behaviors persevered even after the research ceased. Examine alumni reported needing to maintain snacks with them always, so they might by no means have to fret about starvation once more.)
Throughout sustained caloric deprivation, many different organic chemical compounds get out of whack, too, resulting in extra complications, melancholy, nervousness, and chilly intolerance.
Plus, your capacity to pay attention drops, principally as a result of you may’t concentrate on something apart from “WHEN’S MY NEXT MEAL???”
At this low calorie quantity, it’s additionally tough to eat sufficient meals to fulfill all of your nutrient wants, too. So, the chance of malnutrition goes up.
How the 1200-Calorie weight loss program typically fails
Due to all the pieces we talked about above, it’s tough to eat 1200 Energy day after day.
As an alternative, what normally occurs: People nail their calorie targets some days, and wildly exceed it on others.
“Purchasers say ‘I’m consuming 1200 or 1300 Energy a day.’ That’s normally true-ish,” says Brian St. Pierre, MS, RD, Precision Diet’s Director of Diet. “They’re within the ballpark 4 to 5 days every week.”
On the opposite days, nevertheless, dieters discover themselves drawn to extremely indulgent, calorie-dense meals like…
- An entire pizza, plus two beers (2200+ Energy)
- A burrito, two margaritas, chips, and guacamole (2000+ Energy)
- A connoisseur burger with fries and a cola (1500 Energy)
- Pasta with rooster and roasted garlic from The Cheesecake Manufacturing facility (1910 Energy)
Even for those who’re following your common low-cal weight loss program for a lot of the day, simply one of many above meals can push your day by day complete properly above 3000 Energy.
A so-called cheat day can even add a number of 1000’s of energy to your weekly complete. Sure, you consumed 1200 Energy on many days—however your day by day caloric common could also be north of 1800.
Relying in your physique measurement and exercise degree, which will imply no—or simply very sluggish—fats loss.
(Even when weight reduction is taking place, individuals’s expectations—particularly once they’re acutely depressing consuming 1200 Energy 4 or 5 days every week and assume weight must be free-falling off—can set them up for disappointment.)
3 varieties of shoppers who may do properly on a 1200-Calorie weight loss program
We simply made very-low-calorie diets sound like the large unhealthy wolf.
However the fact is, they can be applicable for some individuals like:
► Small ladies: Somebody who stands 4 ft, 10 inches tall, weighs 110 kilos, and doesn’t train may eat 1200 Energy to take care of or lose a small quantity of weight.
► Purchasers adept at superior vitamin protocols: “Should you receives a commission to look a sure method throughout a particular timeframe, you’re typically extra comfy with the tradeoffs,” St. Pierre says.
These shoppers—like weight-classed athletes, determine rivals, or celebrities—have a tendency to make use of extremely low-calorie diets as a short lived software.
Together with water weight manipulation (and perhaps some spray tanning/contouring and good lighting) excessive “cuts” can get these shoppers competitors or photo-shoot prepared.
After the large day is over, they return to a extra sustainable calorie goal.
► Bariatric sufferers: The 1200 Calorie goal may also make sense for somebody who must drop extra pounds quickly for well being causes. Dr. Nowzaradan—one of many stars of the TV present “My 600-Lb. Life”—famously recommends 1200-Calorie diets for his sufferers.
On this case, the particular person ought to endure the weight loss program underneath the route of a medical skilled.
(There’s a lot of misconceptions round low-calorie diets. Should you’re occupied with understanding how they actually have an effect on your physique, learn: Can consuming too little injury your metabolism?)
A greater approach to lose fats—and hold it off.
One resolution to the 1200-Calorie dilemma is counterintuitive: Bump your day by day goal as much as round 1500 Energy, says St. Pierre.
(For males: Go larger, to round 1800, relying in your exercise degree and physique measurement.)
You may surprise: ‘If I (or my shopper) wasn’t shedding weight on a 1200-Calorie weight loss program, how may I presumably drop extra pounds by consuming… MORE? Shouldn’t I eat even LESS?’
Right here’s why it really works: By including just some hundred day by day energy, you’ll scale back the extreme starvation, cravings, fatigue, and meals obsessions that make it so tough to stay constant.
“It feels as for those who’re consuming extra as a result of, on most days, you’re,” says St. Pierre.
“But, when you’ll eat extra every day with 1500 Energy, you’ll seemingly eat much less every week.” The chart beneath reveals how.
(Notice: As a result of nobody consumes the precise calorie quantity—day after day—we’ve different the day by day energy to make them extra lifelike.)
| Aiming for 1500 Every day Energy | Aiming for 1200 Every day Energy | |
| Monday | 1520 | 1205 |
| Tuesday | 1480 | 1180 |
| Wednesday | 1510 | 1215 |
| Thursday | 1490 | 1900 |
| Friday | 1515 | 3200 |
| Saturday | 1485 | 2800 |
| Sunday | 1505 | 1180 |
| Weekly complete: | 10,505 | 13,280 |
| Every day Common: | 1500 | 1811 |
Nevertheless, even after bumping up day by day calorie allowances, some individuals should wrestle with intense starvation and cravings.
So, listed below are 4 methods that make sustaining a calorie deficit somewhat extra comfy, and make fats loss extra sustainable.
1. Embrace lean protein at each meal.
Protein takes longer to digest than carbohydrates or fat. It additionally stimulates the discharge of starvation and appetite-suppressing hormones like cholecystokinin (CCK) in addition to drives down ranges of the starvation hormone ghrelin.
In keeping with a scientific principle often called the protein leverage speculation—sometimes called “protein starvation” in lay circles—the human physique will hold starvation and urge for food fired up till fundamental protein wants are met.
(Notice: There’s conflicting analysis on this speculation… which is why it’s nonetheless termed a speculation—and never, say, a legislation.)
Eat principally low protein meals and also you’ll seemingly stay frustratingly hungry, despite the fact that you’ve consumed a whole lot of energy. 4
(See our “What Ought to I Eat?!” infographic for one of the best protein sources.)
Tips on how to do it:
Intention for a minimum of 4-5 palm-sized parts of lean protein day by day.
Attempt to unfold your consumption out comparatively evenly, consuming 1 to 2 palm-sized parts throughout each meal and snack.
Excessive protein sources embrace fish, shellfish, rooster, turkey, beef, eggs and egg whites, cultured cottage cheese, unflavored Greek yogurt, tofu, tempeh, seitan, and protein powders.
2. Improve your consumption of non-starchy veggies.
Should you ate a whole head of cauliflower, you’d seemingly really feel as for those who had been strolling round with a brick in your abdomen.
But, you’d solely have consumed 146 Energy, give or take.
Examine that to the half slice of pizza you’d get for a similar variety of energy and you’ll perceive why non-starchy veggies may help with fats loss.
Loaded with water and fiber, veggies supply tons of quantity for only a few energy.
In keeping with the Nurses Well being Examine, which tracked the well being outcomes of 133,000 individuals over a number of a long time: Each extra day by day serving of veggies (and fruits too, for that matter) was related to a drop in weight. 5
Tips on how to do it:
Regularly enhance your day by day veggie goal over time, aiming for a minimum of 4 fist-sized servings a day (together with 2-3 cupped handfuls of fruit). This will increase the quantity of meals you eat with out spiking caloric consumption, so you may really feel extra glad with much less.
In fact, typically an order of fries or a slice of pizza is value it—sure, even as an alternative of carrot sticks or a salad entree.
Possible, one of the best meals are constructed with loads of greens and lean protein that can assist you really feel full and glad and small to average quantities of the actually scrumptious mouth-happy meals that deliver you pleasure.
3. Gravitate towards minimally-processed complete meals.
When individuals scale back energy, they generally lean onerous into pre-packaged meals which can be marketed for weight reduction, similar to sugar-free pudding cups, packaged weight loss program bars, fat-free sizzling canines, low-carb bread, and weight loss program shakes.
“These sorts of meals aren’t normally satisfying,” says St. Pierre.
First, they don’t style notably nice, in order that they typically go away you craving for the actual, full-fat, full-carb, full-sugar deal.
On prime of that, they lack key vitamins—particularly protein and fiber—that assist hold starvation and urge for food in examine.
By shifting away from highly-processed meals and “weight loss program meals” and towards minimally-processed complete meals, you’ll robotically eat extra fiber, protein, nutritional vitamins, minerals, and phytochemicals.
Finish end result: You’ll really feel much less hungry and extra glad.
Tips on how to do it:
Begin by making small swaps.
For instance, perhaps you’re a chip-lover, and also you have a tendency to achieve for them (and attain once more) if you’re hungry between meals.
Now assume: What’s a minimally-processed meals that you just like and would even sit up for consuming, that you might hold accessible throughout these snack-attacks, so you’ve an alternative choice to chips?
Chances are high, that alternative can be going to finish up being extra nutritious and satiating—whereas additionally being lower-calorie, partly as a result of it’s more durable to overeat minimally-processed meals. (Not like chips! [shakes fist])
Sounds easy, however we’ve seen individuals dramatically rework their weight loss program over time with this strategy—with method much less effort than individuals who merely attempt to prohibit their meals consumption.
Whenever you’re prepared, you are able to do different swaps, step by step growing your consumption of minimally-processed complete meals till they compose most of your weight loss program.
(For concepts on make these comparatively painless swaps, try this piece: Meal plans normally suck: Listed below are 6 higher methods to rework your weight loss program)
In our expertise, most individuals can discover a wonderful stability between well being and pleasure when minimally-processed meals comprise roughly 70 to 80 % of their total weight loss program.
(Should you’re curious concerning the many different causes highly-processed meals make you are feeling such as you all the time want MORE, try: Why you may’t cease overeating junk meals.)
4. Add resistance coaching.
Often, weight reduction comes from a mix of fats loss and muscle loss.
Muscle loss, nevertheless, is related to a rise within the starvation hormone ghrelin and the urge for food hormone insulin-like development issue (IGF).
Principally, your physique is attempting to take care of muscle mass, so it’s turning up starvation and urge for food to be able to nudge you to eat its constructing blocks.
Although energy coaching doesn’t 100% remove muscle loss throughout weight reduction, it could actually protect most of it.
That’s key as a result of, in accordance with current analysis, preserving lean mass could assist blunt a minimum of a number of the urge for food and starvation will increase people expertise as they drop extra pounds. 6
Tips on how to do it: Should you’re not doing it already, add a twice-weekly energy coaching session to your routine, following a program that targets your whole main muscle teams.

The trustworthy fact: Some starvation is inevitable.
Anybody who tells you you can “drop extra pounds with out starvation” is probably going attempting to promote you one thing.
Should you comply with the 1200 Calorie Weight loss plan—or simply eat fewer energy than your physique is used to—your physique goes to toss up a starvation flare.
That mentioned, for those who…
- Barely bump up your total calorie consumption
- Optimize your consumption of lean protein, veggies, and complete meals (whereas nonetheless permitting some “only for pleasure” treats so that you don’t really feel disadvantaged)
- Incorporate common energy coaching
… You’ll be capable to lose fats with out feeling exceptionally hungry and disadvantaged—and even hold it off.
“You’ll really feel extra glad, you’ll mentally really feel higher, and also you’ll bodily really feel higher,” says St. Pierre. “You’ll be able to nonetheless make progress, simply in a method that sucks rather a lot much less.”
