The key to consistent weight loss is finding a way to limit your calories, as you are limiting your carbohydrates. You need a calorie limiting structure, because if you eat as much as you want on a low carb diet, you probably won’t lose weight. Simple structures work best – whether it’s eating just fish and chicken (fish is 20 calories an ounce and poultry is 30 calories an ounce – compared to pork at 40 calories an ounce, and beef at 50 calories an ounce). Or eat just fast food hamburgers (250 calories without the bun) or just fast food fish sandwiches (150 calories without the bun) or Subway Salads (usually 300-400 calories). Keep your calories under 1500 a day, and you’ll lose consistently. Under 1000 a day is even faster. 500-600 calories a day is almost impossible to do, without diet medication.
