Nutritional Factors affecting Cardiac Risk Weight LDL-C TGs HDL-C BP Glucose
Calories Modest weight loss of 10-15% Reduces BP, improves glucose control, improves serum lipids (cholesterol, HDL-C and triglycerides levels) Diabetes Prevention Program 3234 overweight & obese with hyperinsulinemia - 1/3 given intensive lifestyle intervention, 1/3 metformin, 1/3 usual care Lifestyle intervention reduced incidence of type 2 DM by 58%, metformin by 31% compared to usual care group Lifestyle group achieved 5.6 kg weight loss and exercised 5 times a week for 30 minutes
Calories National Weight Control Registry More than 4,500 people who have lost at least 30 lbs. with 3,000 losing an average of 60 pounds (32.4 kg); keeping this weight off for over 6 years with 30-40% of people are able to maintain a loss of 10% of their body weight. • 60 to 90 minutes of exercise daily • Lower intakes of dietary fat • Lack of exceptions to diet plan • Social support – meetings, family/friends of like mind • Weighing weekly • Alternating strategies – “watching weight” and losing weight
Calories Current popular weight loss approaches
Calories Weight loss approaches • Health clubs with weight loss programs • Commercial weight loss chains • Weight loss websites • Diet food home delivery services • Retail Meal replacements Spent annually Estimated $70 billion in 2010-Market includes registered dietitians and nutritionists, surgical/bariatric programs, prescription medications, and the VLCD/LCD fasting supplement programs More than one way (researched programs) • Ornish, Zone, Atkins, Weight Watchers – all work • No single answer for everyone • Diverse needs and preferences • Pick a safe approach and stick with it
Calories Approaches to encourage Losing weight: • Weigh weekly • Limit sugar • Planning and preparation • Healthy snacks available • Weight loss programs • Exercise variety • Maintaining weight: • Consistent lean protein • Consistent exercise • Renew as priority • Reward yourself • Weigh regularly
Calories Degrees of weight loss • Successful weight loss can contain plateaus and fluctuations • Prevent further weight gain • Maintenance of weight loss that is sustained–successful weight loss is maintained weight loss
Calories What works • Prevention, attention to weight change • Multidisciplinary programs that are 3 to 12 months long • Evidence of commercial weight loss programs leading to success is small but there is weight loss for some • Follow-up important • One-to-one • Social media • Online, App • Long-term success-realistic expectation is 5 to 10 % loss and maintenance (what most can achieve)
LDL-C lowering estimates with diet Approach Potential change Saturated fat < 7% 8-10 % Dietary cholesterol <200 mg 3-5 % 10 lb. weight loss 5-8 % Addition of 5 to 10 grams soluble fiber daily 3-5 % Addition of 2-3 grams plant stanols or sterols 6-15 % Addition of 25 grams soy protein daily3-5 % Total LDL-C lowering 25-35 %
Saturated Fats • Main influence on serum cholesterol • For every 1% increase in consumption of saturated fat calories there is an increase in serum cholesterol of 1.8 mg/dL • Some variation expected given genetic predisposition Recommendations • 7% of calories • 15-20 grams per day based on 2000 to 2500 kcal respectively • Culvers 1 scoop Turtle Sundae 980 calories 27 grams saturated fat
Saturated Fats Meat, poultry, fish are 3 ounce portions
New trend is coconut oil Claims: • Reduce heart disease • Anti-viral • Anti-bacterial • Weight loss • Reduce cancer • Better for cooking • Normalize thyroid • Good for skin and hair • Improve immune function
Types of Saturated Fats • Less LDL-C increase • Increases LDL-C • No LDL-C effect
Trans fat recommendations Limit to <1% of total calories (2000 calories per day = 2 grams) Trans fat in foods • Soft tub margarine, 1 T. 0-2 grams • Stick margarine, 1 T. 2-3.5 grams • Vegetable shortening, 1 T. 0-3 grams • KFC Chicken Pot Pie 14 grams • Burger King hash browns 13 grams • McDonald’s medium fries 5 grams
Cholesterol in Foods • Only found in animal products • Influence on LDL-C more variable than saturated fat • Control intake • Low-fat dairy • Less lean meat • 2-4 egg yolks per week • Shrimp- no more than once a week • Liver? • Goal is < 200 mg daily
Fiber • Soluble (gummy or viscous) • Slows glucose absorption,decreases blood cholesterol • Increases fecal excretion of bile acids • Delays gastric emptying Psyllium supplements–10.2 g (3 doses per day)– see decreased in LDL- C from 5% to 10% depending, more if from typical American diet
Stanols/Sterols • 5 chews per day for 2 grams plant stanols • 6 capsules for 2 grams plant stanols • 4 Tbsp Benecol margarine provide 2 grams
Carbohydrates • Raise TG, lower HDL-C • Processed CHO, especially fructose, can increase TG dramatically • Very low fat diets likely too high in CHO for patients with elevated TG • 50-60% CHO as goal (starches, fruit, sugars)
Fish Oil Supplements • High doses can reduce TG, raise HDL • Low doses can reduce stickiness of blood, reduce inflammation, and irregular heart beats • ? prophylactic 1 gram level, 3- 4 gram for lipid lowering • DHA and EPA are protective components • Cod liver oil and flaxseed oil-not recommended • Check supplement label to assess potency, serving size–many varieties and not regulated or standard
Alcohol • Increases TG production, VLDLs • Effects more pronounced in those who drink large amounts of ETOH • Are overweight/obese • Have diabetes • Have TG disorder • What is a serving? 12 ounce beer 5 ounce wine 1.5 ounces of 80 proof liquor
Sodium Recommendation AHA and US Dietary Guidelines • 2300 mg per day or less, 1500 mg eventual goal • DASH Diet benefits
Plan meals Fruit • Smaller plates • More home prepared • Boost vegetables, limit starch, meat
Summary • Be active • Healthy weight • Mainly plant foods • Unsaturated fats • Smaller amounts of poultry, lean meat and cheese • Less processed foods to reduce salt, sugar and add more fiber • Alcohol moderation HealthDecision™.org is a site that provides data analysis and decision support for health care providers and their patients as they assess and manage the risk of cardiovascular events. https://www.healthdecision.org/index/tool#
