The South Beach Diet was developed by clinical cardiologist Dr. Arthur Agatston and puts some signature spin on a classic low-glycemic index diet. Developed for patients with heart health in mind, the diet seeks to eliminate spikes in blood sugar levels by removing most carbohydrates from your diet (refined flours, pasta, etc.). Once the body has eliminated spikes in blood sugar, complex carbohydrates are slowly reintroduced into your diet and you stay in this phase until you reach your target weight. By the end of the diet, you’re allowed to eat all foods in moderation—even sweets! Though this third phase of the diet recommends some precautions, they aren’t very intrusive on your everyday life.
Unfortunately this reduces the debate to a very simplistic level. Why? Because we know that hunger, appetite, energy expenditure (i.e., metabolic rate), and even our propensity to be active are highly regulated by an increasing list of hormones and signaling molecules, not to mention our genetic inheritance (Bouchard 1994). Moreover these various factors interact with each other – for example: exercise stimulates hunger, calorie restriction increases hunger and decreases spontaneous activity (Keys 1950), calorie restriction reduces metabolic rate, and exercise plus calorie restriction markedly reduces metabolic rate (Phinney 1988).
I did this diet for several months and got down to a weight of 188 lbs at 6’1. I have a video on YouTube about my journey, think i had 60,000 hits about when the book first came out. Loved the cheat day. It does work but no fruit and sugar were hard. I will admit I never got sick, my immune system was top notch and I looked great but it still tough.
