Nutrition 101 Macronutrients Micronutrients ● Protein ● Vitamins ● Carbohydrate ● Minerals ● Fat Alcohol? Water Alcohol ● A drug (ethyl alcohol, ethanol) ○ A central nervous system depressant ● 1 drink = 0.6 ounces of pure ethanol ● Absorbed through the stomach and small intestine into the bloodstream ○ Metabolized to acetate in the liver ■ Acetate is a toxin ■ Slows metabolism of other nutrients to Image - https://alcohol.stanford.edu/faq/count-your-drinks prioritize removal of acetate ○ Circulates in blood until metabolized ■ Feelings of intoxication Energy Balance Israetel, M., Davis, M., Case, J. & Hoffman, J. The Renaissance Diet 2.0. https://myobrain.com/nutrition-essentials/meal-frequency-energy-balance How Diets Work for Weight Loss Diet How It Works Why It Works Macro Track and eat a specific amount Creates a calorie deficit Counting/IIFYM of each macro (carbs, fat, protein) Keto Diet Eat almost 0 carbs, high fat and Creates a calorie deficit moderate protein Intermittent Fasting Eat for only a certain number of Creates a calorie deficit hours per day Paleo Diet Eat no processed food or dairy Creates a calorie deficit Low Carb Diet/Atkins Eat high protein, moderate fat, Creates a calorie deficit low carb Weight Watchers Eat a certain number of “points” Creates a calorie deficit that represent an amount of food What Impact Does Alcohol Have on Body Composition and Weight? Alcohol and Fat Loss ● Can you drink alcohol and still lose weight/body fat? ○ Moderate amounts - yes ● Stay in a calorie deficit ○ We don’t often compensate for liquid calories ● Impact on fat metabolism ● Impact on food choices Image - https://www.nswis.com.au/nutrition/how-to-tackle-boredom-eating/ Alcohol and Weight Management ● Research on alcohol and weight ○ Short-term studies suggest alcohol increases energy intake ○ Longer-term observational studies have not found a consistent relationship ■ Many confounding variables ○ Certainly contributes to some individuals gaining weight ■ Potentially more causative in heavy or binge drinkers versus moderate or light drinkers ● Poppitt SD. Beverage Consumption: Are Alcoholic and Sugary Drinks Tipping the Balance towards Overweight and Obesity? Nutrients. 2015 Aug 11;7(8):6700-18. doi: 10.3390/nu7085304. PMID: 26270675; PMCID: PMC4555143. ● Sayon-Orea C, Martinez-Gonzalez MA, Bes-Rastrollo M. Alcohol consumption and body weight: a systematic review. Nutr Rev. 2011 Aug;69(8):419-31. doi: 10.1111/j.1753-4887.2011.00403.x. PMID: 21790610. Image - https://www.livescience.com/52992-weight-loss-safely-be-healthy.html Alcohol and Tracking Macros ● Need to account for all the calories in an alcoholic beverage in macro terms ● For example, ○ 150 calories in 1 glass of wine ○ Track as 15 carb, 10 fat ■ 15g carb * 4 calories = 60 calories ■ 10g fat * 9 calories = 90 calories ■ Total = 150 calories Alcohol and Fat Metabolism ● While liver is focused on metabolizing acetate ○ Fat oxidation is suppressed ■ 2 drinks ○ Allows fat to be stored more easily ■ IF you are consuming excessive amounts of overall calories and fat ○ Carbohydrate oxidation is also reduced Siler SQ, Neese RA, Hellerstein MK. De novo lipogenesis, lipid kinetics, and whole-body lipid balances in humans after acute alcohol consumption. Am J Clin Nutr. 1999 Nov;70(5):928-36. doi: 10.1093/ajcn/70.5.928.

Alcohol and Food Intake ● How does alcohol influence what and how much you eat? ● Unlike eating a preload of other macronutrients ○ For example, salad or soup before a meal ○ Results in decreased intake at the meal ● Drinking alcohol before a meal ○ Increases intake at a meal ○ Calories from alcohol + calories from more food ● Why? Image - ○ Stimulates appetite https://www.porchdrinking.com/articles/2019/08/07/ ■ Increases hedonic feedback from food ultimate-6er-chicagos-best-pizza-and-beer-pairings/ ○ Reduced recognition of satiety ○ Reduced dietary inhibition Yeomans, M.

PMID: 26270675; PMCID: PMC4555143. Alcohol and Muscle Building ● Alcohol does impact muscle protein synthesis (muscle gain) ● Research examined consuming alcohol after exercise ○ Groups that consumed any alcohol had reduced maximum muscle protein synthesis compared to the group without alcohol ■ Impairs recovery and adaptation to training and/or subsequent performance ● Evelyn B. Parr et al. (2014). Alcohol Ingestion Impairs Maximal Post-Exercise Rates of Myofibrillar Protein Synthesis following a Single Bout of Concurrent Training. https://doi.org/10.1371/journal.pone.0088384 ● ● Alcohol Type ● Are some drinks better than others? ● Weight gain in observational research ○ Wine may be protective against weight gain ○ Spirits and beer more positively associated with weight gain ○ Many studies show no difference ○ Most important factors is total amount ● Sayon-Orea C, Martinez-Gonzalez MA, Bes-Rastrollo M.

Alcohol and Health Benefits ● In observational studies, light to moderate drinking appears to be protective against ○ Cardiovascular disease ■ Heart attack, ischemic stroke, peripheral vascular disease, death from all cardiovascular causes ■ Raises HDL cholesterol, improvements in factors related to blood clotting ○ Gallstones ○ Type 2 diabetes ● Can get most of these same benefits from exercise and healthy eating Alcohol and Health Concerns ● Excessive drinking is associated with ○ Chronic diseases ■ Liver cirrhosis, pancreatitis, various cancers, high blood pressure, depression ○ Weakened immune system ■ Binge drinking even one time can reduce your body’s ability to fight infection even up to 24 hour later ○ Unintentional injuries ○ Violence ○ Fetal alcohol spectrum disorders Alcohol and Sleep ● Even one glass reduces time in deep, REM sleep ○ Less restorative sleep ● Is a sedative but impacts quality of sleep ● Not getting enough sleep ○ Negatively impacts hunger and appetite regulation which can lead to increased calorie intake the next day ○ Negatively impacts glucose control and insulin sensitivity ○ Reduced the use of fat for fuel ○ Increases lean body mass loss and decrease fat mass loss during weight loss So, Should You Drink? Current Alcohol Recommendations ● The 2015-2020 Dietary Guidelines for Americans recommend ○ If alcohol is consumed, it should be in moderation ■ Up to 1 drink per day for women ■ Up to 2 drinks per day for men ■ Only by adults of legal drinking age ○ The Guidelines do not recommend that people who do not drink alcohol start drinking for any reason https://health.gov/our-work/food-nutrition/2015-2020-dietary-guidelines Personal Decision ● Goals ○ Challenges ■ Calories count! ■ Impact on other decisions ○ Opportunities ■ If you enjoy alcohol and it’s an important part of your social life ○ Timeline you want to hit them ■ Unlikely to stop you from hitting goals but, may slow things down ● Personal preference Tying It All Together In Summary ● Weight loss requires you to eat fewer calories than your body burns ○ Alcohol has calories and can impact calories in AND calories out ● Alcohol likely does not have a huge impact on weight when consumed in moderation ○ Choose lower calorie options/watch mixers! ● Alcohol impacts overall health ● Personal decision ○ Impact timeline to goals Looking for support? ● Awareness and accountability are key for making changes ● Get an objective look at your habits ● Envision and achieve success!
