What are these and how do I know what they should be set at?! I am trying to lose weight so unsure what they should be.

SETTING MACRO TARGETS:

There are 4 macronutrients. A high level explanation of each of their functions is:

Protein, which is required for muscle retention/growth
Fat, which is required for healthy body functions
Carbs, which provide energy
Alcohol, which provides for embarrassing photos

Macronutrient goals should really not be based on percentages, but on grams which vary depending on your size and activity levels.

We would recommend, as a rule of thumb, the following:

1g of protein per lb of LBM as a minimum target

0.35g of fat per lb of total body weight as a minimum target

The balance can fall where you wish, taking into account performance, satiety and adherence.

Note: the above protein minimum assumes that you are on a deficit, are undertaking moderate exercise and do not have a significantly low or significantly high body fat percentage. It also assumes that you have no pre-existing medical condition that would require a lower intake.

At a very low body fat percentage or with highly intensive workouts a slightly higher amount of protein is recommended.

Conversely, at a very high body fat percentage or with no or little exercise, a slightly lower amount of protein is acceptable.

Also, at a high BF%, the fats recommendation can be decreased. If you have specific questions about this, please feel free to ask us for our input.

When you have determined the minimum grams of protein and fat, you can calculate the corresponding percentages based on your calorie target to input into MFP. Protein and carbs have 4 calories per gram and fat has 9 calories per gram. Note that MFP only allows 5% increments so you will need to pick the one nearest your desired target.


For example, say someone is 150 lbs with a BF% of 20% on a 2,000 calorie target. Note, a 20% body fat means that someone has a 80% lean body mass (LBM) as LBM is everything except fat (muscle, water, organs, tissue, etc). Their macros in grams would be:

Protein: 1 x 150 x 0.8 (LBM) = 120g x 4 calories = 480 calories divided by 2,000 (calorie target) = 24% - round up to 25%
Fat: 0.35 x 150 = 53.5g x 9 calories = 473 calories divided by 2,000 = 24% - round up to 25%
Carbs: balance of 50%
Remember, protein and fats are minimums and so do not worry about going over on these, carbs would be the variable in this case and you would be under on that macro in order to meet your calorie target.

To change the MFP settings go to My Home -> Goals-> Change Goals-> click Customize and update the macros.

^ That just about covers it...
