Gozer, je heb 2-2.5g per kg eiwit nodig (wat al royaal is) en je zit al op bijna 325g...
Lees dit stukje van bodybuilding.com maar eens:
Macronutrient NeedsOnce you work out calorie needs, you then work out how much of each macronutrient you should aim for. This is one of the areas that is MOST often confused but This should NOT be based on a RATIO of macro intakes. (eg: '30:40:30 or 40:40:20') Your body doesn't CARE what % intake you have. It works based on SUFFICIENT QUANTITY per MASS.
So to try to make it as simple as possible:
1. Protein: Believe it or not - Protein intake is a bit of a controversial issue. In this, the general recommendations given in the 'bodybuilding' area are nearly double the 'standard' recommendations given in the Sports Nutrition Arena.
The GENERAL sports nutrition guideline based on clinical trials suggest that in the face of ADEQUATE calories and CARBS the following protein intakes are sufficient:
STRENGTH training -> 1.2 to 1.6g per KG bodyweight (about .6 / pound)
ENDURANCE training -> 1.4 to 1.8g per KG bodyweight (about .8 / pound)
ADOLESCENT in training -> 1.8 to 2.2g per KG bodyweight (about 1g / pound)
BUT researchers acknowledge that protein becomes MORE important in the context of LOWER calorie intakes, or LOWER carb intakes.
Recent evidence also suggests that protein intakes of 3g/kg help with physiological and psychological stressors associated with high volume or intense training
It is important to note that ADEQUATE v's OPTIMAL is not discussed. And one also needs to consider thermogenics/ satiety/ and personal preference.
General 'bodybuilding' guidelines for protein would be as follows:
- Moderate bodyfat = 1-1.33g per pound TOTAL weight [or ~ 1.25g/pound lean mass if bodyfat known]
- Very Low bodyfat or Very Low Calorie = 1.25 - 1.75g per TOTAL weight [or ~ 1.35 - 2g/pound of lean mass]
- Very HIGH bodyfat, Inactive, = 0.8 to 1g per TOTAL weight [or ~ 1 x LEAN mass]
Anecdotally, most find these HIGHER protein intake better for satiety, partitioning, and blood sugar control. So UNLESS you are specifically guided to use the GENERAL sports nutrition guidelines, I would suggest the BODYBUILDING values.
2. Fats: Generally speaking, although the body can get away with short periods of very low fat, in the long run your body NEEDS fat to maintain general health, satiety, and sanity. Additionally - any form of high intensity training will benefit from a 'fat buffer' in your diet - which acts to control free radical damage and inflammation. General guides:
Average or lean bodyfat: 1 - 2g fat/ kg body weight [between 0.40 - 1g total weight/ pounds]
High bodyfat: 1-2g fat/ LEAN weight [between 0.4 - 1g LEAN weight/ pounds]
IF low calorie dieting - you can decrease further, but as a minimum, I would not suggest LESS than about 0.30g/ pound.
Note 1: Total fat intake is NOT the same as 'essential fats' (essential fats are specific TYPES of fats that are INCLUDED in your total fat intake)...
3. Carbs: For carbs there are no specific 'requirements' for your body so - but carbs are important for athletes, HIGHLY ACTIVE individuals, or those trying to GAIN MASS. [carbs help with workout intensity, health, & satiety (+ sanity)].
If you are an athlete involved in a good volume of training I would suggest you CALCULATE a requirement for carbs as a PRIORITY - then go back and calculate protein / fat:
Moderately active: 4.5 - 6.5 g/ kg (about 2 - 3g/ pound)
High active: 6.5 - 8.5 g/ kg (about 3 - 4g/ pound)
INTENSE activity: + 8.5g / kg (more than 4g/ pound)
For 'others' - to calculate your carbohydrate intake you calculate the calories left over from fats/ protein:
carb cals = Total cal needs - ([protein grams above x 4] + [fat grams above x 9])
carb grams = (p cals + f cals)/ 4
