Nutrition Made Simple! | New Study Crushes “One Size Fits All” Diet? @NutritionMadeSimple | Uploaded January 2023 | Updated October 2024, 12 hours ago.
New diet trial looks at precision nutrition, the right diet for each person.
Many diets can provide benefits. E.g. trials on low fat vs low carb show similar weight loss and metabolic improvements over the long run.
Why do some people do better on diet A and others on diet B?
Overweight volunteers split randomly between 2 diets with same amount of calories but differing in fat content. 34% of calories from fat vs 28%
fat was replaced with protein.
nutrition trials often try to keep protein constant because it affects satiation and intake. many nutrients affect satiation. Fat, fiber etc.
Fiber: in the higher fat diet was a bit under 30g fiber a day and the lower fat diet was a bit over 30g.
supplement of B-glucan (fiber in oats and barley).
Other than that, carbs were kept constant. ~44% of calories from carb in both groups
the fat they added was monounsaturated fat. PUFAs and SFA were kept constant at ~8% of calories each
the higher fat diet had more olive oil and olives. the lower fat diet had more low fat dairy like low fat yogurt and cheese.
They were on the diets for 3 months
They looked for improvements in metabolic parameters like fasting insulin, glucose & insulin after a meal, triglycerides and markers of inflammation
Some people improved on the lower fat diet, some on the higher fat diet.
Insulin resistance= when organs don´t respond normally to insulin so they resist taking up glucose from circulation
You can have insulin resistance in the liver while muscles are still more insulin sensitive. they estimated Insulin resistance in liver and muscle.
people with Insulin resistance in the liver predominantly did better on the higher fat diet. metabolic parameters improved. on the lower fat diet there was no significant change. with muscle Insulin resistance they saw improvement on the lower fat diet, no significant change on higher fat
changes in the microbiome? unsaturated fat improves liver function so its good for liver Insulin resistance?
caloriess didnt differ significantly. changes didn´t seem to be explained by overall weight loss.
there was a small weight loss of ~2% in all groups, weight loss per se didn´t explain it.
Fat loss trended. Visceral fat didnt appear different
gynoid fat, fat accumulated in the hips, thighs and breasts, differed significantly.
muscle Insulin resistance lost more gynoid fat on lower fat diet and saw metabolic improvements on that diet. liver Insulin resistance= less gynoid fat and better metabolic markers on higher fat
precision nutrition is in its infancy
