For most adults, 1,200 calories per day is significantly lower than what is required to maintain a healthy body weight, which for an average woman is around 2,000 calories and 2,500 for an average man. This severe calorie restriction can pose serious health risks and often leads to unsustainable weight loss.

According to a 2022 study, adherence to the 5:2 eating plan was found to be more effective for weight loss than daily caloric restriction in individuals with overweight or obesity. The 5:2 eating plan, also known as the Fast Diet, is a popular form of intermittent fasting that offers a flexible approach to weight management and overall health.

In a landmark 1944 study involving 36 healthy men, one big finding from the Ancel Keys Minnesota Hunger Experiment was that semi-starvation causes severe psychological and behavioral changes, including depression and intense food obsession. The study revealed that these mental impacts were just as debilitating as the physical ones. The research, originally conducted to aid post-war famine relief, became a cornerstone for understanding the interconnectedness of physical and mental health.

The military diet, a controversial rapid weight loss plan, is known for its strict calorie limitations. During the initial three-day phase, followers often ask, "Can I have snacks on the military diet?" The short answer is no, but the rules change significantly during the four 'off' days, allowing for more flexible eating and the reintroduction of snacks.

According to research, long-term calorie restriction can lead to a lower core body temperature as the body conserves energy. This physiological response is one key reason why many people find themselves asking, "Are you colder on an empty stomach?" The sensation is a natural and temporary side effect of your body adapting to a lack of fuel, impacting your metabolism and internal heat production.

Despite its name, the Military Diet has no association with the armed forces, yet it has gained significant popularity for its promise of rapid weight loss. The highly specific meal plan, however, leaves many wondering just how strictly they must adhere to every single detail to achieve the diet's promised results.

Studies reveal that up to 95% of dieters regain lost weight within one to five years, highlighting the complex and often counterproductive nature of weight loss efforts. This reveals why understanding the potential health and performance implications of dieting is crucial for anyone considering restrictive eating.

Poor nutrition is a significant contributing factor to chronic pain and muscle discomfort. It's a common misconception that skipping meals only affects energy levels, but severe under-eating can also lead to electrolyte imbalances, muscle wasting, and pain in your legs.

Teenagers experience a period of rapid growth and development that requires significantly more energy than most adults. A 1200-calorie diet is almost always too low for a teenager, potentially leading to serious health consequences by failing to provide enough fuel for their expanding minds and bodies.

In a 2016 study of contestants from the reality show “The Biggest Loser,” researchers found that a drastic drop in metabolism persisted years after the weight was lost, demonstrating how the body fights against extreme calorie deficits. This phenomenon helps to explain why you get fatter if you don't eat, or more accurately, why extreme dieting can lead to paradoxical weight gain over time.
