5:2 diet is a type of periodic fasting (that does not follow a particular food pattern) which focuses entirely on calorie content. [1] In other words, two days of the week are devoted to consumption of approximately 500 to 600 calories, or about 25% of regular daily caloric intake, with normal calorie intake during the other five days of the week.
The CRON-diet (Calorie Restriction with Optimal Nutrition) [1] is a nutrient-rich, reduced calorie diet developed by Roy Walford, Lisa Walford, and Brian M. Delaney. [2] The CRON-diet involves calorie restriction in the hope that the practice will improve health and retard aging, while still attempting to provide the recommended daily amounts of various nutrients.

A sample nutrition facts label, with instructions from the U.S. Food and Drug Administration [1] The nutrition facts label (also known as the nutrition information panel, and other slight variations) is a label required on most packaged food in many countries, showing what nutrients and other ingredients (to limit and get enough of) are in the food.
VLCD were not found to increase food cravings, and on the contrary, appear to reduce food cravings more than low-calorie diets. [ 29 ] Previous formulations (medical or commercial) of carbohydrate-free very low calorie diets provided 200–800 kcal/day and maintained protein intake, but eliminated any carbohydrate intake and sometimes fat ...
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 ...
varied by: 1) provision of general calorie recommendations, 2) provision of specific calorie information, and 3) whether high- or low-calorie items were more easily accessible. Results suggest that a strictly informational approach may be less effective than subtle guidance in enticing fast-food customers towards healthier meals.
Alternate-day fasting (alternating between a 24-hour "fast day" when the person eats less than 25% of usual energy needs, followed by a 24-hour non-fasting "feast day" period) has been shown to improve cardiovascular and metabolic biomarkers similarly to a calorie restriction diet in people who are overweight, obese or have metabolic syndrome.
A high-protein diet is a diet in which 20% or more of the total daily calories come from protein. [ 1] Many high protein diets are high in saturated fat and restrict intake of carbohydrates. [ 1] Example foods in a high-protein diet include lean beef, chicken or poultry, pork, salmon and tuna, eggs, and soy. [ 2]
