Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Diabetes: Management and Pharmacotherapy

Diabetes: Management and Pharmacotherapy

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Insulin: Dosing Regimen and Adverse Effects

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Background:

The National Diabetes Prevention Program (DPP) is effective but resource-intensive, limiting scalability.
An AI-powered DPP offers a potential solution for wider reach and efficiency.

Purpose of the Study:

To evaluate the effectiveness of an AI-powered DPP (Lark DPP) in weight loss maintenance.
To identify predictors of weight loss success within the AI-powered program.

Main Methods:

Compared 12-month weight loss maintenance between CDC-qualifying and non-qualifying participants.
Used logistic regression to analyze predictors of weight nadir in 3148 members.

Main Results:

CDC qualifiers maintained significantly greater weight loss (5.3%) than non-qualifiers (3.3%) at 12 months.
Weight nadir was 4.2% for all members, with 35% achieving ≥5% weight loss.
Male sex, frequent weigh-ins, and AI coaching exchanges predicted greater weight loss.

Conclusions:

AI-powered DPPs can achieve weight loss and maintenance comparable to other delivery methods.
Engagement with AI coaching and frequent weigh-ins are key drivers of success.
AI offers a scalable and resource-efficient approach to combat the prediabetes epidemic.
