Exploring the highs and lows of very low carbohydrate high fat diets on weight loss and diabetes- and cardiovascular disease-related risk markers: A systematic review.

Aim: Very low carbohydrate high fat diets (VLCHF) are increasingly popular for weight loss and diabetes management, but the risk implications of long-term adherence to a high-fat-diet remain unclear, especially in high-risk populations. This review aimed to examine adherence, weight loss, diabetes- and cardiovascular disease (CVD)-related risk markers in adults consuming VLCHF diets.

Methods: Online databases were searched for randomised controlled trials ≥3 months duration that met a pre-defined macronutrient prescription: VLCHF ≤25%E carbohydrate, >35%E fat; low fat (LF) ≥45%E carbohydrate, ≤30%E fat; and reported energy, saturated fat (SFA), weight, blood glucose, cholesterol and blood pressure (BP).

Medium-term outcomes of converting laparoscopic adjustable gastric band to Roux-en-Y gastric bypass in patients with body mass index <35 kg/m: a uniquely Australian perspective.

Background: The rates of primary laparoscopic adjustable gastric banding (LAGB) have declined in the last 5 years due to band removal secondary to complications and the subsequent weight regain that requires revisional procedures.

Objectives: This study aimed to present medium-term weight loss results and the safety profile of converting LAGB to Roux-en-Y gastric bypass in patients with body mass index (BMI) <35.0 kg/m who presented with LAGB intolerance or complications.
