  1. The Basics ofLow Carb Diets David S. Weed, Psy.D.

  2. What we’ve been told • Dietary fat is to be kept as low as possible • Increased fat and cholesterol levels lead to heart disease • Weight loss only results from reducing calories, increasing exercise, or both • Therefore, the only way to lose weight is to follow a low-fat diet and increase exercise

  3. What people experience • Reduced fat in foods is usually replaced by increased carbohydrates • Cutting caloric intake and/or increasing exercise results in increased hunger • Counting calories is difficult • Meals are rarely satisfying; one always feels hungry • Though weight loss is possible, in time, it is all gained back

  4. What we’ve recently learned • Fats and cholesterol are not all bad • People feel full longer when the foods they eat contain some fat • Carbohydrates convert to body fat easily • Cutting carbs forces your body to burn fat • Fats & proteins rarely convert to body fat • It’s easier to stay on a low-carb diet long-term because hunger is not a problem

  5. Some fats are better than others • Trans fats (hydrogenated oils) are all bad • Despite what we’ve been told, saturated fats are actually good for us! • Large amounts of refined vegetable oils (omega-6) create inflammation, leading to heart disease • Omega 3 fatty acids in fish oil and flax seed reduce inflammation and lower disease risk

  6. Some carbs are better than others • All carbs are made from sugars and convert to glucose in the body and are stored as fat if not burned (exercise) • Simple carbs (sugars) convert to fat easily • Complex carbs (starches, cereals, some vegetables and legumes ) take longer • Refined (white) flours convert to fat faster than whole grain flours

  7. Excess carbs lead to weight gain • Whatever glucose from digested carbs that is not immediately “burned” by muscles or our brain or used for heat is converted by insulin to be stored as fat • Stored fat is only “burned” when too little glucose is available • To burn fat, one has to reduce available glucose, primarily by reducing carb levels

  8. Caloric balance & insulin resistance • “Calories in-calories out” does not take into account how our bodies actually work • The type of food we eat matters as much as how much we eat • Insulin is the hormone that is primarily responsible for glucose conversion to fat • When we gain too much weight over the years, we become “insulin resistant”

  9. Diabetes development • When fat cells no longer accept glucose, our blood sugar levels remain too high • Consistently high blood sugar levels are considered pre-diabetes or diabetes • Chronically high blood sugar over time results in damage to the heart (heart disease), kidneys, retinal blood vessels and nerves (neuropathy)

  10. What to do to prevent this • Reduce carbohydrate intake, especially of refined sugars and flours • Increase muscular exercise to “burn” available blood glucose, as well as increasing heart health, muscle mass, strength, flexibility and bone density • Increase healthy fat intake to reduce hunger and to prevent “diet failure”

  11. What low carb diets can work? • Atkins Diet • Carbohydrate Addict’s • Glycemic Index • Hampton ’s Diet • Mediterranean Diet • The Paleo Diet • South Beach Diet • The Zone Diet • Or, better yet, your own food choices based on what you learn about healthy foods & cooking All reduce carbs & add healthy fats & protein

  12. Why don’t more people use them? • We have been advised to eat low fat diets • We’ve been told that low-carb diets are bad • Research did not initially support low carb • Powerful sources have influenced dietary recommendations (e.g., grain growers) • Low-carb diets can be difficult to follow because carbs are inexpensive and easily available; non-carb fats and proteins are not

  13. If you’re interested • I will offer a weekly support group at no charge at a designated time and location • You choose your own diet and make your own dietary decisions • We will share what’s working and what’s not and offer each other mutual advice • I am not a physician; I will offer what I know and help to facilitate the group
