“I’m a 36 year old female, I weigh 156 pounds, am relatively active, and I work out 5-6 times a week (a mixture of cardio and weights). Weight loss and toning up are my goals, and I would definitely like to lose some belly fat. How much protein do I need a day – I’m so confused by all the conflicting advice out there! Amanda, Boston
Hi Amanda, and thank you for your question. I receive questions about recommended protein intake every day, so you are not alone! Optimal protein is key for both fat burning and building lean muscle mass, and for that reason it is the first component of my ‘Protein, Fibre, Fat’ formula that I use in my Lean and Clean Program.
To lower body fat whilst adding lean muscle tissue I recommend around 1g of protein per lb of ideal body weight a day. For example, I weigh around 115 to 120lbs, so I aim for 120g of protein per day. Studies show that 4 meals a day is beneficial for body composition, so I spread this between my 4 meals (or 3 meals and a snack) a day. This might not be an even spread, and its not perfectly calculated, but I am consistent with eating a good sized serving of protein at each sitting.
If Amanda wanted to lose 16lbs, then she would aim for 140g of protein a day, or 4 x 35g at each meal. Again, I don’t think it is necessary to always be weighing and measuring your food, just start by understanding what 30-35g of protein looks like (this really is the minimum amount per serving), then ‘eyeball’ from there. For example I know there is 30g or protein in my Breakfast Smoothie, and that a medium sized chicken breast, fillet or salmon or 100g of grass fed beef provides around 30g of protein.
For maximum anabolic (muscle building) benefits, it’s best to consume around 30g of protein after strength training. If it’s a short run or HIIT session (30 minutes or less) then it’s fine to wait until your next meal.
