Put very simply protein is essential- if you don’t eat enough then your body will cannibalise its own lean tissue in order to gain access to the amino acids it requires. Cannibalism isn’t good, people get hurt.
Here are the benefits of eating protein
The science shows that you really don’t need more than 0.8 grams per lb of bodyweight, however for the sake of simplifying calculations I would advise anywhere between 0.8 and 1 grams of protein per kilo or per 1.6-1.8 grams per kg of bodyweight. You can eat more, and for some people the best way to manage hunger levels is to eat more protein.
Ideally we’d be calculating protein needs based on lean body mass levels, this works really well but it can be overly complex and fiddly to work out the numbers on this. So for fat loss clients I like to make things super simple.
If you weigh 220 lbs but your goal is 200 lbs then you can easily jump in at between 160-200 grams of protein per day.
If you weigh 180 lbs but your goal is 140lbs then use between 112-140 grams of protein per day.
Muscle Protein Synthesis (MPS) is dependent on a couple of factors. Firstly, total protein intake and secondly consuming sufficient leucine to trigger the MTOR pathway and allow MPS.
Leucine= amino acid that governs the MTOR signalling pathway
MTOR(mammalian target of rapamycin, you don’t need to remember this)= trigger for Muscle Protein Synthesis
So, to recap. Both total protein consumption and per meal leucine intake are important. Animal sources of protein contain decent amounts of the amino acid leucine. So if you are consuming animal sources of protein with some frequency through the day you will by and large not need to worry about this.
Aim for servings of 0.3g/kg of protein per meal
For an 80kg man this would mean 24 grams of protein per meal from an animal source in order to hit the leucine threshold.
60kg female this would mean at least 18 grams of protein per meal.
Protein has 4 calories per gram
So male 100kg but wants to be 85kg
TARGET BW 85 kg x 2.2 = 187 lbs TARGET BW
LOW END 187 lbs x 0.8 = 150 grams of protein
HIGH END 187 lbs x 1= 187 grams of protein
We have now established the boundaries for daily protein intake which we can adjust based on personal preference and hunger levels.
150 grams of protein is 600 calories
187 grams of protein is 748 calories
If you prefer to eat 3 meals per day then you might opt for 50 grams of protein at each serving
If you prefer 4 meals per day then you might increase the protein to 160 grams and 40 at each serving.
It would be very impractical to try to eat 187 grams of protein in 2-3 meals- so a preference for a higher protein intake would require more meals from a practical standpoint.
Protein is important
Eat a decent amount
Multiple servings are better up to a point.
1.Work out your target calories- useful reference here
2.Workout your protein intake
3.Divide Protein evenly between 3-5 meals according to preference-.
4.Total Calories- Protein calories= Carbs and Fat Allowance
5.Divide remaining calories according to preference
Example: Sedentary Female 150lbs want to be 130lbs
1.10 x 150 = 1500 calories
2.Protein intake=130x 0.8/1= 104 to 130 grams per day- choose a figure that best suits your appetite and personal preference- we’ll go with 120 here
120 over 4 meals = 30 grams per meal.
LOW CARB APPROACH- 120 grams for protein =480 calories
50 grams for carbs = 200 calories,
90 grams of fat = 810 cals,
BALANCED APPROACH- 120 grams of protein = 480 calories
100 grams of carbs= 400 calories,
55 grams of fat =495 cals
Low Carb: 30 grams of protein,
12 grams of carbs
22.5 grams of fat
Balanced: 30 grams of protein
25 grams of carbs
14 grams of fat
Track progress and if it stalls then drop calories or increase activity.
3 eggs=21 grams of protein, 18 grams of fat
20 grams of cheese= 5 grams of protein, 7 grams of fat
100 grams of bell peppers=9 grams of carbs
100 grams of mushrooms=3.5 grams of carbs
150 grams of Salmon= 30 grams of protein, 20 grams of fat
150 grams of Chicken Breast= 30 grams of protein
Olive Oil 1 tbsp= 15 grams of fat
100 grams of butternut squash=12 grams of carbs
100 grams of spinach= not much of anything
200 grams of greek yoghurt =
