The global rise in obesity presents a significant challenge to public health in the 21st century. In the United States alone, obesity contributes to approximately 300,000 deaths annually, reduces life expectancy, and incurs substantial healthcare costs. White adipose tissue (WAT), beyond its role in energy storage, functions as an endocrine organ, secreting adipokines that influence appetite, satiety, and glucose and lipid metabolism. Research is ongoing to identify and understand the role of these adipokines in the hopes of developing effective weight management strategies. While individual results may vary, the following science-backed tips, including insights gleaned from studies on Spexin, can help you on your weight loss journey.
The Importance of Limiting Calorie-Containing Liquids
A crucial aspect of weight loss involves being mindful of liquid calories. During a diet, every calorie counts. Therefore, limiting the intake of calorie-containing liquids is essential for successful weight management.
Mindful Dining Out
Restaurant meals often contain hidden calories that can derail your weight loss efforts. Here are some strategies for navigating restaurant dining:
Request Sauces and Dressings on the Side
A simple yet effective strategy is to request sauces and dressings on the side. This allows you to control the amount you consume, significantly reducing your calorie intake.
Be Aware of Cooking Methods
Food at restaurants often tastes delicious because it's cooked with generous amounts of oil. While frying enhances palatability, it also substantially increases the calorie content. Opt for grilled, baked, or steamed dishes whenever possible.

Request Accommodations
Don't hesitate to ask for modifications to your meal. Most restaurants are willing to accommodate requests, such as preparing food without added oil or substituting vegetables for starchy sides. Offering a generous tip for obliging can further encourage cooperation.
The Role of Vegetables
Fill half of your plate with non-starchy vegetables. This is a great strategy for cutting calories.
The Impact of Spexin on Weight Loss
Spexin, a peptide whose gene expression is markedly down-regulated in obese human fat, has shown promise in weight management. Studies indicate that Spexin may function as an adipocyte-expressed satiety factor.
Spexin and Caloric Intake
Research on dietary-induced obese (DIO) rodents demonstrated that Spexin administration reduced caloric intake by approximately 32%, leading to corresponding weight loss.
Spexin and Metabolic Parameters
Further studies on DIO mice revealed that Spexin treatment significantly reduced the respiratory exchange ratio (RER) at night, indicating an increase in lipid oxidation. Spexin also increased locomotion, suggesting a potential role in energy expenditure.

Spexin and Fatty Acid Uptake
In vitro experiments showed that Spexin inhibited facilitated fatty acid (FA) uptake into DIO mouse adipocytes, suggesting a direct effect on adipocyte metabolism.
Spexin and Human Studies
Studies have shown that circulating Spexin levels are lower in obese individuals compared to non-obese individuals. Spexin concentrations were negatively correlated with leptin levels and the Vmax for long chain fatty acid (LCFA) uptake by omental adipocytes.
Relevance of Iwijn De Vlaminck's Research
Iwijn De Vlaminck, an associate professor of biomedical engineering at Cornell University, focuses on developing precision medicine technologies to monitor and study infectious and immune-related diseases. His work on liquid biopsies and spatial mapping of the microbiome and transcriptome could potentially contribute to a better understanding of the role of adipokines like Spexin in metabolic regulation and obesity.
Intermittent Fasting
Intermittent fasting (IF) involves cycling between periods of eating and fasting on a regular schedule. This approach can be an effective strategy for weight loss and overall health.
Time-Restricted Eating
One popular IF method is time-restricted eating, where you limit your eating window to a specific number of hours each day. This can help reduce overall calorie intake and improve metabolic health.

Benefits of Intermittent Fasting
By restricting your eating window, intermittent fasting can shift the focus away from food during your fasting period, making it easier to adhere to a calorie-controlled diet.
The Problem With Carbohydrates
Limit starchy, carby foods like pizza, pasta, and panini.
The Thermic Effect of Activity (TEA)
Incorporate organized physical activity (i.e. exercise) into your routine. The thermic effect of activity will help you burn calories.
