Gastric band (GB) surgery achieved a median weight loss of 9.8% at 10 years compared to 5.6% in the medical group (median difference 4.2%; p = .008).

GB surgery may be a more effective option for weight loss in overweight individuals with type 2 diabetes compared to medical care.

The review proposes practical ways to implement intermittent energy restriction methodologies.

Practitioners can utilize the proposed methods for better implementation of IER.

Participants lost nearly 40% of their initial body weight (38% ± 9%), with 17% from fat-free mass (FFM) and 83% from fat.

Practitioners should note the significant fat loss compared to FFM loss in weight management programs.

Consumers currently taking a GLP-1 consume significantly fewer calories than the other groups surveyed, with calorie reduction while taking a GLP-1 for weight loss estimated to be around 720 to 990 calories.

Practitioners should consider that GLP-1 users may have lower caloric intake, which could influence dietary recommendations.

GLP-1 users most likely reduce consumption of processed foods, sugar-sweetened beverages, refined grains, and beef.

Dietitians may need to adjust food recommendations for patients using GLP-1 based on their reduced consumption of certain food types.

Individuals in the Persistent+GLP-1 naive cohort achieved a mean weight reduction of 12.9% at 6-months post-index.

Practitioners can expect significant weight loss in eligible patients using tirzepatide over a 6-month period.

Lifestyle interventions targeting diet and physical activity are effective in sustaining weight loss up to two years with extended care.

Health professionals should consider implementing lifestyle interventions focusing on diet and physical activity for weight loss maintenance.

Pharmacology combined with lifestyle interventions was effective in sustaining long term weight loss.

Combining pharmacological treatments with lifestyle changes may enhance weight loss maintenance strategies.

There is important evidence that the use of behavioural weight loss interventions are effective in sustaining long term weight loss.

Behavioural weight loss interventions should be considered for long-term weight management.

Moderate and balanced consumption of macronutrients associated with calorie restriction is recommended for patients with metabolic syndrome.

Practitioners should recommend a balanced diet with calorie restriction for patients with metabolic syndrome.

Participants in the Kaupapa Māori fitness and exercise programme lost an estimated 5.2 kg per participant per 100 days.

Fitness programmes designed with cultural values can effectively support weight loss in Māori populations.

Moderate and balanced consumption of macronutrients associated with calorie restriction is recommended for metabolic syndrome.

Practitioners should recommend a balanced diet with calorie restriction for patients with metabolic syndrome.

High ultraprocessed food (UPF) intake is consistently linked to negative health outcomes.

Practitioners should be aware of the negative health implications of high UPF consumption.

Food policies that limit UPF intake are supported by evidence.

Policymakers should consider implementing regulations to reduce UPF consumption.

Increasing intake of plant foods is recommended for cardiovascular health.

Health practitioners should encourage patients to increase plant food consumption.

Substituting saturated fats with polyunsaturated and monounsaturated oils is recommended.

Health practitioners should advise patients to use healthier oils.

Regular consumption of fish with a focus on omega-3 enrichment is recommended.

Health practitioners should recommend fish consumption for omega-3 benefits.

Exercise influences energy regulation and facilitates a reduction in body fat.

Incorporating exercise can help reduce body fat without dietary changes.

Higher exercise energy expenditures are associated with progressive loss of body fat.

Increasing exercise intensity or duration may enhance fat loss.

Weight loss can be achieved with either a healthy low-carbohydrate diet (LCD) or a healthy low-fat diet (LFD).

Both LCD and LFD can be effective for weight loss in individuals with overweight or obesity.

The onset of type 2 diabetes can be delayed or prevented chiefly by weight loss.

Weight loss should be emphasized in diabetes prevention strategies.

Early detection and proper medical management can greatly reduce the likelihood of serious complications from diabetes.

Implement early detection and management protocols to minimize complications in diabetic patients.

The assessment and promotion of physical activity in clinical settings appears to be effective.

Health professionals should incorporate physical activity assessment and promotion in clinical practice.

Seventeen studies demonstrated improvements in physical activity levels as a result of the interventions.

Practitioners can expect to see improvements in patient physical activity levels with appropriate interventions.
