If I had a dollar for every time someone has asked, “how many grams of carbs should I have each day?” I’d have enough money to buy a few copies of Madonna’s latest album… or fill up my car with gas. I think I’d go for the latter.
While I, nor anyone else, can tell you exactly how many grams of carbs you should take in each day, there are some guidelines I can give you to help you reach your goals.
Two Key Points Regarding Carb Intake
- If your goal is to lose fat, then you should eat less carbs.
- If your goal is to build muscle, then you should eat more carbs.
Additionally, you need to consider how important strength, stamina, mental clarity, and a good mood are to you. As your carb intake reaches critically low levels, all of those things can suffer.
So if your job requires you to be vivacious, chipper, and smart as a whip, then a very low carb diet (at least long term) is probably not realistic for you. Don’t worry, there are ways to manipulate your carbs so that you can burn lots of fat without feeling and/or performing like poop.
Before we get to specific carb guidelines, let me give you a couple more nuggets of information.
Your fat and carbohydrate intake should be inversely proportional. If you eat more carbs, you should eat less fat, and vice versa.
Here are three sets of guidelines for daily carb intake. (Select your goal and match with your bodyweight.)
I want to get lean FAST and I don’t care how tough it is!
Bodyweight Carb Intake
100 – 150 pounds 30 – 70 grams
151 – 200 pounds 50 – 100 grams
201 and up pounds 75 – 150 grams
I want to get lean fairly quickly but still feel good and maintain most of my strength.
Bodyweight Carb Intake
100 – 150 pounds 70 – 125 grams
151 – 200 pounds 100 – 150 grams
201 and up pounds 150 – 200 grams
I want to slowly lean up, feel great, keep (and even gain) muscle and strength.
Bodyweight Carb Intake
100 – 150 pounds 100 – 200 grams
151 – 200 pounds 150 – 300 grams
201 and up pounds 200 – 350 grams
Summary
If you use the above carb intake guidelines, consume moderate amounts of healthy fat (~40g), eat plenty of protein (~1g/lb), all spread over 5 or 6 small meals per day, you will most likely make substantial improvements in your physique!
As always, train hard and expect success!

hi. i do have one question. if I follow this program od dieting, i assume after some time theroretically I will reach plateau in my weight, right. So I was wondering when making next step, increasing bodyweight, should I increase carbohydrates intake and leave protein intake the same, or vice versa, incrasing protein intake and leaving carb intake the same. I wanted to hear your opinion because once i get lean i wouldnt like to gain fat
. thanks in advance
i was a bit unclear in my previous post even to myself. what I wanted to ask is how much should I increase protein intake when increasing carb intake and is it possible to increase protein intake and leave carb intake intact to gain more muscle. I currently weigh 90 kg and I am eating around 300g of carbs and 270 g of protein per day. Thanks in advance
Hi Clay,
I’m wondering if you count fiber(veggies) as part of these carb counts? I’ve heard of some people that do and some that dont.
Thanks!
