|March 29, 2008
Summary
The Atkins diet, a popular low-carbohydrate (LC) weight-reducing plan, significantly decreased caloric intake and body weight in overweight adults. Weight loss on the Atkins diet is primarily attributed to reduced calorie consumption.
Area of Science:
- Nutrition Science
- Dietary Interventions
- Obesity Research
Background:
- Low-carbohydrate (LC) diets are widely adopted for weight management.
- The Atkins diet is a popular LC diet with distinct phases.
Purpose of the Study:
- To evaluate dietary intake and weight changes in adults following the Atkins diet.
- To assess the impact of Atkins' Induction and Ongoing Weight Loss phases on caloric and nutrient intake.
Main Methods:
- Short-term longitudinal study involving 18 overweight/obese adults (BMI >/= 25 kg/m²).
- Participants followed Atkins' Induction and Ongoing Weight Loss phases for 2 weeks each.
- Dietary intake (calories, nutrients) assessed via 3-day food diaries; body weight measured post-diet phases.
Main Results:
- Mean caloric intake significantly decreased from 2481 kcal/day (Baseline) to 1400 kcal/day (Induction) and 1558 kcal/day (Ongoing Weight Loss).
- Body weight significantly reduced from 107.4 kg (Baseline) to 103.6 kg (Induction) and 102.1 kg (Ongoing Weight Loss).
- Decreased caloric intake strongly correlated with observed weight loss (r=0.64 for Induction, r=0.40 for Ongoing Weight Loss).
Conclusions:
- Self-implementation of Atkins' diet phases leads to reduced caloric intake in overweight/obese adults.
- Weight loss achieved on the Atkins diet is directly linked to the reduction in daily caloric consumption.
- The diet also significantly alters dietary micronutrient intake.

01:24Metabolic States of the Body: Fasting and Starvation
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
01:15Nursing Evaluation
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

01:28Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

01:25Diabetic Ketoacidosis l: Introduction
DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...
