Expert’s Insight: Appetite Control And Caloric Intake On Low-carb Ketogenic Diets

I am so pleased to introduce Dr. William Lagakos who has accepted my request to write an article for my blog! He is an expert in obesity, inflammation, and insulin resistance. In this post, Bill will present the findings from three recent controlled trials focused on the effects of low-carbohydrate vs low-calorie diets on appetite and weight loss. Bill runs his own blog and has authored his best-selling book, The poor, misunderstood calorie, which is one of the best resources on human energy metabolism. As most of you who follow the ketogenic diet know, "calorie is not a calorie" but calories are not insignificant: caloric intake definitely plays a role in weight loss. The regulation of appetite is a complicated thing, with many players and many, MANY moving parts. One of these parts is diet composition. That is, ‘what’ you eat impacts ‘how much food’ or ‘how many calories’ for which you’re hungry. One theory is that carbohydrates are a major driver; as restricting them is very effective at reducing appetite in obese populations. Exhibit A. In 2008, Westman and colleagues compared two diets of vastly different macronutrient compositions in a population of obese type 2 Continue reading >>

    For me it doesn't So by eating high fat if I eat until I'm full I lose weight very, very, very slowly because I'm taking in too many calories I'm assuming.
    I know everyone says Atkins needs to be high fat but why?
    Even if I stay below 20 grams of carbs a day I don't lose weight unless I stay below 1600 calories.
    Staying low Carb does control my blood sugar and my Carb/sugar cravings so I don't want to stop but I do need to keep losing. right now I can't get below 175

    see, I think we are all different. I need to eat very low fat with slightly higher carbs to feel appetite control. When I eat high fat low carb, I get hungry, almost bingey. If I eat a more vegetable based diet, I am free of cravings and hunger. I just think we all have different genetic organizations. I am definitely in favour of lowish carb--but I had to find my way of having appetite suppression, and it is not the same as others.

    Ketosis definitely suppresses my appetite. What's more, not eating carby food doesn't lead to blood sugar highs and lows, so I don't feel starving three hours after eating something like oatmeal. So the combination of eating very low carb and being in ketosis makes a difference for my hunger pattern.
    I eat very low carb (fewer than 20g total), moderate protein (~120g--enough to nourish my LBM), and enough fat to make up the rest of my calories, because fat is the macronutrient that won't affect blood sugar nor be stored as fat. So yes I eat high fat, but that doesn't mean that I'm eating a ton of calories. I don't count calories, but I generally average about 1800-2000 calories per day, with some outliers.
    If you need to keep your calories below 1600, do that.

    You've heard the story before: when you eat carbohydrate-rich foods that digest quickly, it sends your blood sugar and insulin levels soaring, then your blood sugar level comes crashing back down and you feel hungry and cranky.

The preferred source of fuel is fat, but under certain circumstances, we can shift the body to using more sugar rather than fat. At times, such as being chased by a rabid dog, ...

    About a year ago, my endocrinologist determined that I was exhibiting signs of insulin resistance. In short, my body requires more than the average amount of insulin to cover carbohydrate. She suggested that I start taking metformin, noting that it would do two things for me: It would decrease the amount of insulin I need to take and it would help curb my appetite, thus resulting in weight loss. When I first got on it, I thought it was great. My ...
