1,200 calories

I am writing this only because it may come as helpful to someone who is serious about actually knowing and understanding what is what... For anyone who wants to adhere to whatever other philosophy they may be married to, that is okay. You do what you want to your bodies and let others make their own decisions.

For OVERWEIGHT people, diets under 1200 Cal CAN be nutritionally adequate. In fact there have been tests done on obese people who were fasted for a YEAR on 400 cal per day. Without consequences.

There is NO SUCH study that determined that a person should or shouldn't eat 1200 kilo-calories as a minimum for anything. It is a number quoted out of a book of American Medical Society for Sports Medicine. The number was determined as a conversational (NOT STUDIED) estimate on how a lean athlete can lose 2 lbs per week, based on the idea that a female athlete has a total daily energy expenditure of 2100 Cal.

This is information from 1970's and it is painfully inaccurate and remains inaccurate till the day. An average female athlete expends a lot more than 2100 per day as do men a lot more than 2800. Not to mention that lean people should not be training and under-eating or losing weight unless they are optimizing for performance. Meaning a female athlete made to eat 1200 Cal a day should sue the idiot that makes her do that.

On the note of a SAFE MINIMUM, This is where the story changes a lot...

An overweight individual HAS AMPLE amounts of caloric energy stored in their "*kitten*"... So to lose body fat that person MUST consume optimal amount of PROTEIN (to preserve organs and muscle mass) and DIETARY FAT (to support brain function, hormonal system and vitamin absorption) and adequate MICRO nutrients (these are required in very small amounts). They DO NOT need to consume ANY carbohydrate. None. Zero (I don't have the will power to explain the biochemistry that has been well studied that confirms this - most of you can read... if you want to know the actual truth you will search without bias and study thoroughly - if you are inclined to study look for gluconeogenesys and related works).

In short, based on everything we know today, the minimum amount of food an OVERWEIGHT person can eat and MAINTAIN health is based on their minimal protein requirement, minimal dietary fat requirement and whatever they choose to get their MICRO's from (small amount of leafy greens or pills if you want to minimize calories).

Now... World Health Organization Numbers

They state that it takes a minimum of 0.33 grams of protein per POUND of body weight and that this is adjusted to include 3rd world countries. (minimum is not optimum) They state that optimum for sedentary individuals is higher.. 1 gram of protein per kilogram of body weight (athletes more, even 2+ grams per kilogram) and also around 0.6 grams of dietary fat per kilogram of body weight (0.3-0.4 per pound).

By the way USDA states that you need 120 grams of carbs per day and then literally 10 pages later it admits that you don't need any at all... (go figure). Administration that created the most obese, unhealthiest people on the planet...

=======
So a woman that weighs 65 kilograms and wants to lose 5 kilograms (provided that she is in fact 5 kilograms overweight) CAN SAFELY eat:

65 grams of protein * 4 Cal = 256 Cal from protein
39 grams of fat * 9 cal = 351 Cal from dietary fat (butter, coconut oil, olive oil, fish oil, fat in consumed meats)
25 grams of net carbs * 4 Cal = 100 Cal from low sugar vegetables (to insure micros) - this is a lot of salad suitable vegetables by the way

The rest of her energy needs will be readily supplied from her own fat storage supply...

This comes out to 707 Cal that a 65kg average female CAN SAFELY consume as long as she insures that her MICRO's are adequate. By the way there are many NON doctor supervised diets that follow these principles to varying degrees.

If you care immensely to preserve muscle mass and want to be on the safe side, you should figure out your LEAN mass and consume enough protein to support it (usually it is lean-mass in pounds multiplied by 0.8). Some people need more.

Should this be done for 6 months without taking a break?,, it CAN be but I wouldn't push past 3 months for very overweight people and for 4 weeks maximum for less overweight people..

I have done this (twice so far) intermittently without ANY issues whatsoever and lost up to 4 pounds per week. ZERO negative consequences. YES I WAS HUNGRY and I definitely felt like I could eat something but the question here is what is safe. THAT IS SAFE,, albeit it is unpleasant and it isn't necessary if you are okay with losing at a more moderate pace.

A 65kg woman that is 172 cm tall (5'8'') and that is sedentary has total daily energy needs of only 1,714 Cal. to lose ONE pound per week she would need to eat 1214 Cal and that would only apply until she reached 62kg when her needs would drop to 1,673 Cal and her intake would have to drop to 1173 Cal. Failure to adjust the diet and further reduce calories is why half the world lives with the conviction that it's hardest to shed the last stubborn 10 pounds,,, it is not,,, and it is safe to drop your calories a lot if you know what to do and what not to do.

I do this aggressive method 2 to 4 weeks then for 1 - 2 weeks I eat maintenance calories (around 2200 Cal for me).

And no,,, rapid fat loss doesn't cause rapid re-gain... That's entirely untrue as are many other things. Rapid re-gain is a result of abandoning the appropriate macros and micros and re-introducing more calories, refined sugars and less activity.

By the way,, "starvation mode" in a weight loss sense doesn't exist. There is a biochemical process called adaptive thermogenesis (and it is fairly insignificant) that has been ignorantly misinterpreted and in the same way used by soft headed people to justify cheating in diets.

Real starvation mode is a condition that occurs when a person doesn't get enough protein and enough micro's. It is a malnutrition state that doesn't have to be related to low calories. You can starve nutritionally even when you eat more calories than you need. For a person that gets enough protein, fat and micros, calories ONLY come into play when the person is already completely lean (which is rare). If you are fat and you eat enough protein, dietary fat and micro's you can't starve.

Feeling crappy because you are eating less than your TDEE (total daily energy expenditure) is normal. Your body will fight you for food until you enter nutritional ketosis. At that point things become easier.

And one more related thing,,, plateaus happen because people don't adjust their diets to support ongoing weight loss (not because of mythical starvation mode)... If you started at 220 lbs and you reached 180 lbs and you started the diet at 1500 cal per day,,, you HAVE to reduce your calories (probably to 1350 Cal) to account for adaptive thermogenesis... which happened because you lost 40 pounds, not because you ate reduced calories...
