Energy balance
A Low Energy Diet (LED) of 800-1000 kcal/day induces significant weight loss in overweight individuals without apparent risk, and when combined with exercise, aids in weight maintenance and improves metabolic markers.
A Low Energy Diet (800-1000 kcal/day) using structured meal replacements (soups, shakes) can produce significant weight loss safely. To maintain this loss, the protocol transitions to a high-protein, low-glycemic index maintenance diet, supported by regular dietician visits.
In overweight but otherwise healthy subjects, a low energy diet (LED), defined as 800 – 1000 kcal/day, resulted in a considerable weight loss with no apparent risk [12]; however, there are no studies describing the use of LED in patients with CAD.
Why this rating
The paper is a protocol; it cites previous studies on healthy subjects but notes a lack of specific studies in CAD patients.
