According to the American Academy of Nutrition and Dietetics, morbidly obese individuals should consume 22 calories for every kilogram they weigh. At 300lbs (136kg), your brother needs about 2,992 calories daily based on the recommendation.
On average, obese people consume about 3,500 calories per day to maintain their weight. However, this number can vary depending on a person's individual metabolism, activity level, and other factors.
Therefore, individuals who cut their daily intake to 1,200 calories can expect to lose some weight. This can be beneficial for people who are overweight or obese. Some research suggests that a low calorie diet, such as a 1,200 calorie diet, offers additional health benefits.
Not the way to go. This is a starvation diet and not good for anyone, including obese people. The lowest advised is 800 cal for a very obese person and that is under a doctor's strict supervision.
Your body can meet the majority of your calorie requirements from stored fat, but total starvation is fatal in 8-12 weeks, regardless of initial body weight. Within one or two days of your last meal, your body will have exhausted all the glycogen stored in the liver and muscles.
In anorexia, death from organ failure or myocardial infarction is fairly common (up to 20 percent of cases end this way) and tends to happen when body weight has fallen to between 60 and 80 pounds (although it can occur at any time).
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
In addition, consuming as few as 800 calories daily may not give you the energy you need for daily living and regular physical activity, especially if you eat the same foods every day. Talk to your doctor or dietitian to make sure you get the nutrients you need while on a very low-calorie diet.
It is possible to eat 4,000 or 5,000—or even 10,000 calories—a day and still be malnourished! While the average American diet is filled with fat and calories, it can often lack the essential vitamins and nutrients that your body needs to function healthfully.
The CDC state that a person can safely and effectively lose about 1–2 lb a week. Based on those numbers, in a month, a person could safely lose 4–8 lb.

Obesity is a complex and chronic disease with many causes. It is not simply a result of overeating. Research has shown that genetics can play a significant role in determining a person's body weight, particularly for morbidly obese people.
The odds of being obese were approximately 50% higher among those consuming fast-food 2 or more times per week compared with those consuming it less than once per week.
A person who has super morbid obesity has a BMI of 50 or higher, nearly twice the BMI level of someone who is classified as overweight. A BMI of 30 or higher is considered obese. Obesity is often divided into three categories—Class I, Class II and Class III—with Class III including all BMIs of 40 or greater.
Most adults need a minimum of 2000 calories to sustain metabolism, muscle activity, and brain function. However, too many calories can lead to weight gain and a variety of diseases.
The participants on the 800 calorie diet made a gradual return to a more normal diet after the 12 weeks of 800 calories. Both groups were then followed for two years. The results in the rapid weight loss group were astounding. Average weight loss was 10.5kg and nearly ¼ of participants lost over 15kg.
So, if you're eating 1,200 calories and not losing weight, it could be that your body is really struggling to function on so little fuel and your metabolism is not functioning well enough to respond to a deficit in the way you'd like.
According to studies, for every 1 kg of weight loss, 7700 calories are needed, or 1000 calories are lost 0.13 kg.
People may try this diet to control their food intake and lose weight. Some research suggests that the average female can limit their daily caloric intake to 1,500 calories or less to drop 1 pound per week. The average male may consume up to 2,000 calories a day to lose the same amount of weight.
How much weight a person needs to lose for it to be noticeable is also subjective as it depends on your frame and starting body mass index, according to Guzman. On average, a 15 to 20-pound loss (approximately 2 to 5 percent of your starting body weight) is enough to notice "significant changes in your body," he said.
There are also different tiers of anorexia based on BMI ranging from mild (<17.5), moderate (16-16.99), and severe (15-15.99), to extreme (<15). A BMI below 13.5 can lead to organ failure, while a BMI below 12 can be life-threatening.
Known as Long-breath diet by Ryosuke, this Japanese technique for losing belly fat quickly involves standing in a certain position, taking 3-second breath and exhaling strongly for 7 seconds. It has been previously found that breathing exercises can help you with weight loss.
