Calorie restriction or Caloric restriction (CR) is the practice of limiting dietary energy intake in the hope that it will improve health and retard aging.
In human subjects, CR has been shown to lower cholesterol, fasting glucose, and blood pressure.
Some consider these to be biomarkers of aging, since there is a correlation between these markers and risk of diseases associated with aging.
Except for houseflies, animal species tested with CR so far, including primates, rats, mice, spiders, Drosophila, C. elegans and rotifers, have shown lifespan extension.
CR is the only known dietary measure capable of extending maximum lifespan, as opposed to average lifespan.
In CR, energy intake is minimized, but sufficient quantities of vitamins, minerals and other important nutrients must be eaten.

CR is the only known dietary measure capable of extending maximum lifespan... Now, we have an idea of why. Those eating fewer calories show a dramatic drop in their night-time metabolic rates and a small, but significant drop in their night-time body temperature. |

Better sleep isn't the only benefit you get from eating fewer calories. In addition to losing 12% of the body weight over two years without the need for exercise, one also improves mood and reduces tension, plus boosts sex drive.

I'm fully aware of the fact that eating a calorie-restricted diet is a hard thing to do, but science suggests that it’s worth considering, for its overall health benefits are even harder to ignore. The latest study on the topic shows a link between calorie-restriction, fat loss and reduced oxidative damage to our cells, with an intriguing connection to a slowdown in metabolism while asleep.

A calorie-restricted diet will consist mostly of veggies, low-fat dairy, lean meat, fish, berries and eggs. These foods are low in calories and have a satiating effect. A 1,000-calorie meal plan could look like this:
Breakfast
2 hard-boiled eggs: 120 calories, 12 grams of protein and 8 grams of fat
1 medium banana: 105 calories, 1.2 grams of protein, 0.3 grams of fat, 26.9 grams of carbs and 3.1 grams of fiber
Snack
Cottage cheese (1/2 cup): 90 calories, 12.9 grams of protein, 2.5 grams of fat and 6 grams of carbs
Lunch
Roasted chicken breast (3.5 oz): 107 calories, 21.4 grams of protein and 0.8 grams of fat
1 medium sweet potato: 115 calories, 2 grams of protein, 0.2 grams of fat, 26.7 grams of carbs and
3.8 grams of fiber
Chopped salad blend (2.9 oz): 25 calories, 2 grams of protein, 5 grams of carbs and 2 grams of fiber
Snack
Low-fat Greek yogurt (3.5 oz): 73 calories, 9.9 grams of protein, 1.9 grams of carbs and 3.9 grams of fiber
Almonds (1 oz): 164 calories, 6 grams of protein, 14.1 grams of fat, 6.1 grams of carbs and 3.5 grams of fiber
Dinner
Wild salmon (2.9 oz, cooked): 155 calories, 21.6 grams of protein, 6.9 grams of fat
Kale (1 cup, cooked): 42 calories, 3.4 grams of protein, 1.4 grams of fat, 6.2 grams of carbs and 4.7 grams of fiber

"There seem to be two mechanisms by which a restricted-calorie diet increases life span," says Mark Mattson, PhD, chief of the Laboratory of Neurosciences at the National Institute on Aging. "First, it reduces free radical production, or the production of highly damaging forms of oxygen, and the second is that calorie restriction increases the resistance of cells to stress. We think that both of these are important in protecting against a number of different diseases that have a negative impact on life span, such as cardiovascular diseases and cancer."

I went on a 1000 calorie per day diet in April. At the time, I was 240 pounds, and had high cholesterol and was pre-diabetic. I also had acid reflux issues and high blood pressure. I went on this diet to lose weight and hopefully improve my health. I now weigh 181 pounds, am completely off meds for acid reflux, my blood sugar is normal and so is my cholesterol. My blood pressure has also drastically improved. I don't know if a low calorie diet will increase my lifespan, though I have heard that before, but I do believe it has helped my quality of life. My intent has been to continue to stay around 1000 calories till I reach the 170s, and then eat enough to maintain that weight. I do recommend a low calorie diet for weight loss. It is simpler than trying to use the numerous diet programs.

Normally, people diet to lose weight and reduce the risk of getting serious diseases. Well, I guess an indirect effect is to live longer without cancer and a heart attack. |

Everything that has the potential to improve people's health situation should be tested and evaluated. Science likes to treat different diets as 'hystericl whims' and won't go anywhere near then for fear of being ridiculed.

Calorie restriction doesn’t have to happen every day.
You can eat normal food on alernate days, then every other day, you eat only one meal with maybe 30 percent of your usual daily calorie intake.”
And there’s the 5:2 diet, in which you eat a normal diet five days of the week and only 30 percent of what you would usually eat on the other two days.
But whichever it is you choose, you have to make sure you don’t overeat on the 'normal' days.

According to a widely cited study published in the journal Cell Metabolism in May 2018, cutting just 15 percent of your calorie intake can slow aging and cause significant weight loss in as little as two years.

To put things in perspective:
With evidence dating back to 1935, when Cornell scientist Clive McCay unexpectedly discovered that rats on a calorie-restricted diet lived nearly 30% longer than those on 'normal' diets, according to a Cornell press release, scientists have been testing the impact of a calorie-restricted diet on everything from mice and worms, to flies, spiders, guppies, dogs and primates.
