Understanding the Basics of Weight Loss
Weight loss can seem elusive with the plethora of fad diets and trendy exercise routines, but fundamentally, it boils down to a simple physiological principle. “Weight loss occurs when there is a sustained calorie deficit, leading the body to utilize stored fat for energy,” explains Crystal Scott, R.D., a registered dietitian with Top Nutrition Coaching. This typically involves a combination of reduced calorie intake and increased physical activity.
In essence, weight loss happens when you consume fewer calories than you burn. The body then turns to its fat stores for energy. Regular physical activity boosts this process, making weight loss more achievable.
Key Factors Influencing Weight Loss
While the basic formula for weight loss is straightforward, various individual factors can influence the process, including:
Genetics
“Each person’s genetic makeup can influence how their body responds to diet and exercise, impacting weight loss,” says Scott. Studies have shown a link between genetics and an individual’s tendency to gain weight.
Starting Weight
Those with higher initial weights often lose weight more quickly at first. “The more you weigh, the more energy your body needs to function,” explains Megan Hilbert, R.D., also with Top Nutrition Coaching. However, as weight loss progresses, the rate of loss tends to slow down for everyone.
Hormones
“Hormonal imbalances or conditions such as thyroid disorders can affect weight loss progress,” Scott notes. Conditions like polycystic ovarian syndrome, Cushing’s disease, menopause, and low testosterone can also cause weight fluctuations.
Overall Health and Lifestyle
Medical conditions, physical ability, sleep hygiene, and general physical activity all play significant roles in a person’s ability to lose weight, according to Scott.
