Therefore, dietary interventions remain the cornerstone of weight-management strategies, and pharmacologic and surgical interventions also aim to improve dietary management.Ĭomplex factors shape and influence diets, especially for weight management. 10 However, obesogenic environments, including social determinants, cultures, and food supply systems, are challenging to modify. Obesogenic environments and biological and psychological factors all contribute to obesity. Does a high-protein diet aid in weight loss and maintenance? Can a ketogenic diet burn fat? Do carbohydrates increase abdominal fat? Can intermittent fasting help one lose weight? New dietary information has only added to the current confusion due to several controversial dietary regimens, and there is no clear guidance on the optimal diet for weight loss.
9 However, several questions remain unanswered. 8 Recently, intermittent fasting and time-restricted eating have become popular and seem to be effective for weight loss. 7 In contrast, another review revealed that the Atkins, Weight Watchers, and Zone diets resulted in modest and similar long-term weight loss after 1 year.
6 Another study examined the effects of popular diets without specific calorie targets and showed that the Atkins diet resulted in clinically meaningful weight loss after 6 months.
Meal planning for weight loss driver#
4, 5 According to a meta-analysis of several diet programs, calorie restriction was the primary driver of weight loss, followed by macronutrient composition. Optimal diets for weight management have been a topic of debate not only among researchers, nutrition experts, and healthcare professionals, but also among the general public. 1 Obesity has become one of the most important public health problems globally and is strongly associated with type 2 diabetes mellitus (T2DM) cardiovascular diseases including myocardial infarction and stroke osteoarthritis obstructive sleep apnea depression and some types of cancer, such as breast, ovarian, prostate, liver, kidney, and colon cancer. More than 650 million adults worldwide suffer from obesity, and the prevalence of this condition has increased rapidly during the past 50 years. Hence, strategies for weight loss and its maintenance should be individualized, and healthcare providers must choose the best strategy based on patient preferences. Our review indicated that there is no single best strategy for weight management. Meal timing is also an important factor in weight management, and higher-calorie breakfasts in combination with overnight fasting may help to prevent obesity. Some macronutrient composition-based diets, such as the ketogenic diet or high-protein diet, could be considered in some cases, although the potential risks and long-term effectiveness remain unknown. A low-calorie diet with a low fat or carbohydrate content has been recommended however, in some cases, a very-low-calorie diet is required for a short period.
An energy deficit is the most important factor in weight loss. In this review, we identified evidence-based dietary strategies for weight management based on these three components. Weight management depends upon complex factors such as amount of food eaten, type of food eaten, and timing of meals. Obesity has become one of the most important public health problems worldwide, which suggests the need for evidence-based dietary strategies for weight loss and its maintenance.
