Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity.As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another.
The military diet plan is a restrictive way of eating for weight loss, per dietitians. Here, find the plan’s pros, cons, safety info, and meal examples.
[23] [24] Combining VLCD with other obesity therapies yield more effective results in weight loss.

[41] [42] A meta-analysis found no difference between diet types (low-fat, low-carbohydrate, and low-calorie), with a 2–4 kilograms (4.4–8.8 lb) weight loss. [43] This level of weight loss is by itself insufficient to move a person from an 'obese' body mass index (BMI) category to a 'normal' BMI.
The concept of "protein-sparing modified fast" (PSMF) was described by George Blackburn in the early 1970s as an intensive weight-loss diet designed to mitigate the harms associated with protein-calorie malnutrition [8] and nitrogen losses induced by either acute illness or hypocaloric diets in patients with obesity, in order to adapt the patient's metabolism sufficiently to use endogenous fat ...
Mild calorie restriction may be beneficial for pregnant women to reduce weight gain (without weight loss) and reduce perinatal risks for both the mother and child. [11] [12] For overweight or obese individuals, calorie restriction may improve health through weight loss, although a gradual weight regain of 1–2 kg (2.2–4.4 lb) per year may occur.

Preventive nutrition has been known about for a long time. The philosopher Hippocrates (460-377 BC) believed that nutrition had a significant impact on maintaining health and that the best way to prevent diseases was to "let food be your medicine and medicine be your food.” [4] Meyer-Abich (2005) also believed that nutrition was foundational to a healthy life.
