◐Partially SupportedA plant-based protein blend showed similar stimulation of protein synthesis to whey protein but lower plasma amino acid levels.

◐Partially SupportedHypoglycemia is a state of severe hunger driven by a physiological need for fuel, distinct from normal hunger cues.

◐Partially SupportedWhen calories are equated, time-restricted eating does not show a difference in weight loss, fat loss, or most health biomarkers compared to other eating patterns.

◐Partially SupportedThe thermic effect of protein is 20% to 30%, and protein is more satiating than carbohydrate or fat.

◐Partially SupportedCalorie trackers may not be accurate for absolute values but can be relatively confident for within-subject comparisons of effort.

◐Partially SupportedNon-exercise activity thermogenesis (NEAT) can account for hundreds to nearly 1,000 calories burned per day.

◐Partially SupportedIsolated potato protein has an essential amino acid content comparable to whey protein.

◐Partially SupportedDifferent sources of calories can have differential effects on energy expenditure and appetite.

◐Partially SupportedHigh HDL cholesterol does not negate the increased risk associated with high LDL cholesterol.

◐Partially SupportedMetabolic adaptation typically averages around 15% and causes a reduction in BMR beyond expected body mass loss.

◐Partially SupportedA calorie represents the potential chemical energy in food's macronutrients.

◐Partially SupportedA 10% reduction in body weight can lead to a decrease in NEAT of almost 500 calories per day.

◐Partially SupportedChallenging oneself mentally is associated with a reduced risk of Alzheimer's and age-related cognitive decline.

◐Partially SupportedBeliefs and the power of suggestion can influence physiological outcomes.

◐Partially SupportedLow inflammation combined with high LDL cholesterol confers a higher risk than low inflammation with low LDL cholesterol.

◐Partially SupportedFasting does not appear to increase the body's ability to assimilate more protein after a fast, based on studies using stable isotopes to assess protein metabolism.

◐Partially SupportedGLP-1 signaling impacts hypothalamic neurons controlling satiety and activates gut mechanosensors, creating a perception of fullness.

◐Partially SupportedIsoenergetic exchanges of different carbohydrates generally do not show significant differences in markers of health like HbA1c, fasting blood glucose, or blood lipids.

◐Partially SupportedHigh-intensity interval training does not lead to greater body fat loss compared to moderate or low-intensity cardio when total work is equated.

◐Partially SupportedThe original effectiveness of the keto diet for weight loss was partly due to the difficulty of consuming processed foods within that framework, a limitation that has been overcome with modern processed keto products.

◐Partially SupportedDoing what is easy in the short term leads to a harder life, while doing what is hard in the short term leads to an easier life.

◐Partially SupportedFor diet maintenance or sub-caloric intake, males and females show no significant differences in response or achievement of similar results from similar calorie deficits.

✕Not SupportedThe idea that the body can only assimilate 30 grams of protein per meal is likely outdated, and individuals consuming 2 grams per kilogram of body weight across two to three meals per day should not be overly concerned about this threshold.

◐Partially SupportedThe thermic effect of food represents about 5% to 10% of total daily energy expenditure.

◐Partially SupportedAspartame's artificial or chemical taste perception may diminish with repeated exposure.

◐Partially SupportedResistance training stimulates appetite significantly more than cardiovascular exercise approximately 60-90 minutes post-workout.

◐Partially SupportedVegan and vegetarian protein sources are often co-packaged with significant amounts of carbohydrates and/or fat.

◐Partially SupportedProlonged exposure to sweetness can lead to desensitization of taste buds, making less sweet foods taste bland initially, but taste buds adjust over time.

◐Partially SupportedMinimally processed foods are generally those that would not survive long without refrigeration, such as apples, bananas, and oatmeal.

◐Partially SupportedArtificial sweeteners are likely not healthful for lean individuals without health problems, though current data does not strongly indicate they are unhealthy.

◐Partially SupportedFood labels can have up to a 20% error in calorie content.

◐Partially SupportedStearic acid does not tend to raise LDL cholesterol, unlike saturated fat as a whole.

◐Partially SupportedPlain baked potatoes rank very high on the satiety index.

◐Partially SupportedThe effects of artificial sweeteners on blood glucose may be transient.

◐Partially SupportedAchieving completely unprocessed food is difficult as most foods undergo some form of processing.

◐Partially SupportedMovement after a meal, such as a walk, may help reduce circulating glucose levels.

◐Partially SupportedNicotine acts as an appetite suppressant and can increase focus.

◐Partially SupportedResting metabolic rate accounts for 50% to 70% of total daily energy expenditure for most people.

◐Partially SupportedConsuming very sweet things can increase cravings for sweet foods.

◐Partially SupportedBuilding muscle can be achieved with similar effects on muscle growth using light loads up to 30 reps or heavy loads for low reps, as long as the sets are taken close to failure.

◐Partially SupportedMuscle building involves a balance between protein synthesis and degradation.

◐Partially SupportedExtreme forms of fasting may negatively impact lean body mass, but this can be mitigated by resistance training.

◐Partially SupportedAbsolute load, rather than just percentage of one-rep max, is important for inducing hypertrophy in elite powerlifters.

◐Partially SupportedPlant-based diets can support the development of impressive muscle mass.

◐Partially SupportedArtificial sweeteners are not inert and may have physiological effects.

◐Partially SupportedCarb blockers, such as white kidney bean extract, can reduce carbohydrate absorption.

◐Partially SupportedInfused essential amino acids increased protein synthesis, peaked at 60 minutes, returned to baseline by 120 minutes, and did not increase again.

◐Partially SupportedIndividual gut microbiomes may influence the ability to extract energy from fiber.

◐Partially SupportedIf carb blockers were highly effective at blocking absorption, they would likely cause diarrhea.
