Diet: Why Strict Diets Fail at Long-Term Weight Loss.
While a highly restrictive diet can help an individual lose weight, experts note that severely cutting calories triggers physiological responses—including increased hunger, reduced satiety, lower energy expenditure, and loss of muscle mass—that promote weight regain, sometimes reclaiming up to 70% of the weight lost. Instead, those seeking a healthier weight should take a more balanced approach focused on nutrient quality, adequate protein and fiber, and sustainable lifestyle changes such as regular exercise, stress management, and reduced sedentary time.

Chiropractic: Treatment for Degenerative Lumbar Spondylolisthesis.
Degenerative lumbar spondylolisthesis is a condition in which age-related changes to the spine cause one lower back vertebra to gradually slip forward over the one beneath it, potentially leading to back pain, leg pain, or nerve compression. A recent study found that low-force spinal mobilization and soft-tissue-focused manual therapies—such as those provided by doctors of chiropractic—can serve as an effective intervention for improving pain, function, walking capacity, and quality of life for patients with degenerative lumbar spondylolisthesis.
