In patients with mild to moderate Parkinson's disease, protein intake below 1 g/kg/day is independently associated with positive sarcopenia screening, higher fat mass index, and lower relative skeletal muscle index.

If you have mild to moderate Parkinson's, ensure you are eating at least 1 gram of protein per kilogram of body weight daily. This study links lower intake to loss of muscle strength and increased body fat. Talk to your doctor about timing your protein intake around your medication to maximize both drug effectiveness and muscle health.

Higher intake of total essential amino acids (EAAs) and branched-chain amino acids (BCAAs), normalized to body weight, is positively associated with handgrip strength relative to body mass index (HS/BMI) in urban adults aged 33-71.

To support muscle strength, especially as you age, prioritize foods rich in essential amino acids, particularly branched-chain amino acids (BCAAs). Good sources include red meats, poultry, dairy, and eggs. While total protein matters, the specific quality and leucine content of these proteins appear to be key drivers for maintaining handgrip strength relative to body weight. Ensure you are consuming adequate amounts of these high-quality proteins daily.

A personalized ketogenic diet (≤20g carbs/day) induces rapid fat loss and preserves skeletal muscle mass in the short term (3 months), but long-term adherence drops significantly after the initial phase.

Start with a strict limit of 20g carbs daily, focusing on healthy fats and moderate protein. Expect rapid fat loss in the first 3 months, but be prepared for a drop-off in motivation. To stay on track, monitor ketones, manage electrolytes to avoid 'keto flu', and work with a professional to adjust calories if weight loss stalls.

Intermittent Fasting or Time-Restricted Eating (TRE) combined with a Low-Carbohydrate diet can improve glycemic control and reduce insulin requirements in T2DM patients, though it carries a risk of hypoglycemia if medications are not adjusted.

If you are interested in Time-Restricted Eating (eating within an 8-10 hour window), do it alongside a low-carb diet. However, because fasting lowers blood sugar, you MUST work with your doctor to reduce or stop your diabetes medications (especially insulin) to avoid dangerous lows. Use a glucose monitor to track your levels.

In older adults with low energy intake, consuming carbohydrates above 65% of total energy significantly increases the risk of physical frailty, whereas substituting carbohydrate energy with fat energy reduces this risk.

If you are an older adult who struggles to eat enough calories, avoid making carbohydrates the vast majority of your diet (over 65% of energy). Instead, ensure you are getting enough fat. Replacing some carbohydrate calories with fat calories may help reduce the risk of frailty. Focus on meeting total energy needs first, then balance macros by including adequate fats.

Lower carbohydrate intake (≤ 5.0 g/kg/d) does not impair lean soft tissue gains or strength adaptations in resistance-trained men compared to higher intake (> 5.0 g/kg/d), though higher intake increases the probability of responsiveness.

If you are already trained, you don't need to eat massive amounts of carbs to build muscle or get strong. Eating around 5g/kg of carbs works just as well as eating more for most people. However, if you want to maximize your odds of seeing big gains, eating more than 5g/kg might help you respond better, especially for smaller muscle groups like arms.

Silibinin (150-300 mg) and thistle extract inhibit human pancreatic lipase in vivo, leading to increased fecal fat excretion and reduced waist circumference, with a significantly lower adverse effect profile compared to orlistat.

Taking 150-300 mg of silibinin or thistle extract with meals may help reduce abdominal fat by blocking some dietary fat absorption, with fewer gastrointestinal side effects than prescription fat-blockers like orlistat. However, this was observed in a very short-term study of healthy, normal-weight people, so long-term efficacy and safety for weight loss in obese individuals remain unproven.

BCAA supplementation combined with resistance training significantly reduces BMI in young women, whereas meat protein supplementation results in significantly higher final BMI compared to BCAAs.

If you are a young woman doing resistance training, BCAA supplementation might help lower your BMI more effectively than meat protein supplements, though muscle mass gains were not significantly different across groups. Ensure you are consuming enough total protein (approx 1.4g/kg) and training consistently.

Meat protein supplementation combined with resistance training results in significantly higher final body weight and BMI compared to BCAA and vegan protein supplements in young women.

If your goal is to lower BMI while doing resistance training, meat protein supplements might not be the best choice compared to BCAAs or vegan proteins in young women. You may end up with a higher final body weight.

Household food insecurity is independently associated with higher odds of low muscle mass in U.S. adults, with lower total protein intake acting as a significant partial mediator of this association.

If you are experiencing food insecurity, prioritize protein intake as much as possible, as it is a key factor in maintaining muscle mass. While you cannot control food availability, focusing on protein-rich foods within your budget may help mitigate muscle loss.

High polygenic risk for obesity interacts with specific nutrient intakes (particularly saturated fat and trans fat) to accentuate BMI increases, whereas omega-3 intake may attenuate this genetic susceptibility.

If you have a high genetic risk for obesity, the quality of fat you eat matters more than you might think. Prioritize omega-3 fatty acids and minimize trans fats and saturated fats, as these nutrients can significantly blunt the BMI-increasing effects of your genetic predisposition. Total fat quantity alone is less predictive than fat type.

Ketogenic diet is effective for short-term weight loss in obese individuals by shifting energy metabolism to ketone bodies.

To lose weight using a ketogenic diet, restrict carbohydrates to under 50 grams per day while consuming high fat and adequate protein. This shifts your body to burn ketones for energy. Be aware that strict versions can be hard to taste and sustain long-term, so consider phased approaches like VLCKD with careful monitoring.

High carbohydrate intake (61% of energy) is associated with lower total mortality and cardiovascular events compared to high fat intake (23.5% of energy).

Focus on the quality of your diet rather than just cutting fat. The PURE study suggests that a diet with higher carbohydrates and lower fat (as traditionally practiced in many parts of the world) may be associated with better health outcomes than high-fat diets. However, this does not mean you should consume excessive amounts of refined sugars or processed foods. Instead, prioritize whole food sources of carbohydrates and healthy fats.

Body composition-targeted agents (e.g., bimagrumab) preserve or increase lean mass while reducing fat mass, addressing the functional decline associated with rapid weight loss.

If you are concerned about losing muscle while losing weight, ask your doctor about body composition-targeted therapies. Drugs like bimagrumab are designed to burn fat while building or preserving muscle, which helps maintain strength and function.

In 60–65-year-old women, skeletal muscle mass is independently predicted by protein intake per kilogram of body weight, whereas in men of the same age, muscle mass is associated with protein intake and hard leisure-time physical activity, but not other dietary factors.

For seniors aged 60-65, maintaining muscle mass requires sex-specific strategies. Women should focus on adequate protein intake per kg of body weight combined with moderate health-related physical activity, as other nutrients like magnesium and phosphorus also play a role. Men should prioritize total protein intake and engage in harder, vigorous leisure-time physical activity, as other dietary factors do not significantly predict muscle mass in this group.

Regular meal patterns and larger, less frequent meals maximize the Thermic Effect of Food (TEF) compared to irregular or frequent small meals.

Try eating fewer, larger meals rather than grazing throughout the day. Regular, larger meals may trigger a higher thermic effect of food (more calories burned during digestion) and help manage hunger signals better than frequent small snacks.

Replacing carbohydrates with saturated fatty acids (SFA) increases the prevalence of dyslipidemia, specifically elevated total cholesterol and LDL-C, in Filipino women.

For Filipino women, swapping carbohydrates for saturated fats (like those in coconut oil or animal fats common in their diet) raises the risk of high cholesterol and LDL. To improve lipid profiles, prioritize unsaturated fats (MUFA/PUFA) or complex carbohydrates instead of saturated fats when adjusting macronutrient ratios.

Replacing carbohydrates with Monounsaturated Fats (MUFA) is associated with a reduced prevalence of dyslipidemia in Filipino women.

For Filipino women, swapping carbohydrates for Monounsaturated Fats (found in olive oil, avocados, nuts) lowers the risk of dyslipidemia. This suggests that increasing MUFA intake is a beneficial dietary strategy for improving lipid profiles.

GLP-1 based therapies (Retatrutide, Ebenatide) cause significant muscle mass loss at higher doses, whereas lower doses or standard GLP-1 agonists preserve muscle mass better.

If you are using high-dose GLP-1 based therapies (like Retatrutide 8-12mg), be aware that you may lose more muscle than with lower doses or standard GLP-1s. This is a trade-off for greater fat loss. Prioritize protein intake and resistance training to protect your muscle mass, especially if you are older.

Orlistat, a pancreatic lipase inhibitor, promotes modest weight loss and improves gut microbiota diversity (increasing Akkermansia and Verrucomicrobia), but its efficacy is significantly lower than GLP-1 agonists.

Orlistat blocks fat absorption, leading to modest weight loss and improved gut bacteria diversity. However, it is significantly less effective than GLP-1 agonists. Side effects like bloating and diarrhea are common if dietary fat is not strictly limited.

Among vegan dieters, higher consumption of ultra-processed foods (UPF) is associated with reduced odds of inadequate protein intake, whereas higher consumption of unprocessed/minimally processed foods (UMPF) is associated with increased odds of inadequate protein intake.

If you are vegan, do not strictly avoid all ultra-processed foods (UPF) if it compromises your protein intake. This study found that vegans who consumed more UPF (like textured soy protein or supplements) were much less likely to have inadequate protein intake compared to those who ate mostly unprocessed foods. To ensure you get enough protein, consider including protein supplements or textured soy products, as unprocessed plant proteins alone may require impractical volumes to meet requirements.

Adherence to the DASH diet is inversely associated with a lower risk of developing NAFLD and reduced liver fat content.

Incorporate more fruits, vegetables, whole grains, and low-fat dairy into your diet while reducing red meat, sweets, and sugary drinks. High adherence to this pattern is linked to a significantly lower risk of developing NAFLD.

High-protein diets improve insulin sensitivity primarily through weight loss and increased satiety, but may have negative effects if protein quality is poor.

Increasing protein can help you feel full and preserve muscle, which supports weight loss. However, don't obsess over hitting extreme protein targets. Focus on high-quality protein sources and ensure you are getting enough fiber and nutrients. If you are not losing weight, high protein alone may not improve your insulin sensitivity.

Low-sodium diets are significantly associated with hypertension and dyslipidaemia management, but not significantly associated with diabetes in this population.

If you have high blood pressure or high cholesterol, reducing your sodium intake to under 2000mg per day is associated with better health outcomes. However, this specific restriction may not help manage diabetes.
