If lean muscle if your goal, high protein bulking is the way. That's what bro-science that's just been confirmed by pro-science - w/ non-lifting young, lean men.

Measurements are indicated as follows: (1) after 2 wk of run-in; (2) after 2 wk of intervention (Period 1); and (3) after4wkof intervention (Period 2). BW, body weight; CD, control diet; HD, high-fat, hypercaloric diet; HP, high-protein condition (within the high-fat, hypercaloric diet); IHL, intrahepatic lipid; NP, normalprotein condition (within the high-fat, hypercaloric diet); REE, resting energy expenditure (Rietman. 2014).

normal protein: 15.4% protein | 39.4% fat | 45.2% carbohydrates

high protein: 25.7% protein | 37.7% fat | 36.6% carbohydrates

all food items chosen from the free-choice list were recorded. Participants came to the research facility every working day during lunchtime

they consumed a hot meal, which was weighed to the nearest gram by the research dieticians,

breakfast, evening bread meals, snacks, beverages, and all meals for the weekends were provided in take-home packages,

all the foods were precalculated for macronutrient composition and energy content for each individual participant by the research dieticians

Yes, even protein can make you fat (learn more) Don't forget to train + keep your energy surplus moderate: Please keep in mind that this was a six-weeks study in the course of which the subjects were on a ~15-18% energy surplus. As a SuppVersity reader you will remember the results of the Please keep in mind that this was a six-weeks study in the course of which the subjects were on a ~15-18% energy surplus. As areader you will remember the results of the Bray study , which indicate that on a +40% energy surplus, even "high protein" is not going to save your ass, thighs and midsection from the deposition of unwanted body fat ( learn more )... And that's going to happen particularly fast, if you don't train as regularly as the resistance trained subjects of Jose Antonio's protein overfeeding study I wrote about on May 18, 2014 | read it

Figure 3: Relative differences in body composition and glucose management (Rietman. 2014); data based on pooled means from the NP and HP conditions; note : the only statistically significant differences were observed for the increase in lean and decrease in fat mass. Bottom Line: So, bulking on a "high" protein diet (ca. 211g/day) is healthier than doing the same thing on diet with only "normal" amount of protein (133g/day). And that's true irrespective of whether we judge by classic markers of metabolic health, i.e. serum triglycerides and liver lipid levels or by a parameter that's probably more dear to your heart and inspite of its aesthetic value in as much a health parameter as the trigs and liver fat: Body fat,lean mass, fasting blood sugar & insulin levels (see Figure 2).



In that the study confirms the general advice to get the lion's share of your caloric surplus on a bulk from protein from both, an aesthetic (body fat), as well as a health perspective (body fat, glucose management, fatty acid metabolism and liver health).

We all know "protein is good", but why is it bashed by scientists all around the world as a carcinogenic obesogen in the headlines of many of the major science news outlets, then? I can't answer this question, but after the "Meat is a major contributor to the dietary anti-oxidant intake of the average Spaniard" study I wrote about on theFacebook page, yesterday ( learn more ), today'sarticle is going to be evidence number two you can use in any discussion with protein deficient vegan about the usefulness of a dietary protein.Being based on a peer-reviewed study from thein the Netherlands, the results of the study at hand are (almost) beyond doubt.The study design is simple and easy to explain. Annemarie Rietman and colleagues recruited twenty-nine healthy, young,Caucasian men and women participated in this strictly controlled dietary intervention study. Participants had no family history of type 2 diabetes and were not taking any medication. The total dietary intervention lasted for 6 weeks. All participants started with a 2-week run-in period on a weight-maintaining CD (27.8 En% fat, 16.9 En% protein, 55.3 En% carbohydrates) to get familiarized with the dietary regimen and to adapt to the same diet.Thereafter, participants were randomly assigned to either the HD group (n= 19) or the CD reference group (n= 10). Interestingly, the participants were unaware of their assigned diets until the end of the study, although participants could have guessed their study status based on the diets.After the run-in, participants in the high energy intake (HD) group were overfed with 2 MJ/d, i.e. 477.69kcal/day, for the following 4 wk of intervention. The corresponding macros wereWithin the HD group, a randomized crossover design consisting of 2 periods of 2 wk was applied - practically speaking, this means that all subjects were on both diets for two weeks each:The diets of the participants were (according to the scienceists) "strictly controlled" (Rietman. 2014) during the entire 6-wk study period. In that the diet was composed of an identical 90% baseline to cover their basic needs and a 10% extra they could select from a predefined free-choice list. Moreover, ...Moreover, a diary on physical activity had to be filled out every day. Thus, the scientists tried to emulate a tightly controlled "quasi metabolic ward" scenario under free-living conditions.Now, if you look at the data inyou will realize that the energy-distributions were not as significantly different as they are if you compare the average bodybuilder to the average Joe. With 16.9 en%, 15.4 en%, and 25.7 en% for the CD, NP diet, and HP diet, respectively, the total dietary protein intake from mixed origin (dairy, animal, and plant sources, with the contribution of dairy protein more prominent in the HP condition | 55% of the protein came from dairy in the high protein vs. normal protein and control condition compared with 30% for both other diets) amounted to212g/day that's way less that the subjects in Jose Antonio's recent " protein excess study " were consuming ( learn more ).Diet and physical activity levels are is yet not the only difference between the studies. The outcome measures were different as well: The triglyceride and intra-hepatic fat levels, indicators of beginning non-alcoholic fatty liver disease and thus, as you as areader know, impeding insulin resistance ( learn more ) you can see intell you provide insights into the overall metabolic health of the subject, the previously cited study did not have to offer.And we are talking about a health, here of which the data intells you that it was not compromised by the high protein diet phases at all. In fact, "a trend toward lower IHL and plasma TG concentrations during the HP condition compared with the NP condition was observed" (Rietman. 2014).
