1) Carb Portion Controlling — asked by Mike Reyes:
"How many grams of carbs should be consumed in a day? Is there a ratio or math equation to determine how much is needed?"
“The amount of carbs to eat in a day depends on several variables including your (1) body size, (2) activity level, (3) fitness goals, and (4) genetics. The Dietary Guidelines for Americans suggest around 55% of your calories each day should come from carbohydrates. Most bodybuilders consume around 50% of total calories from carbs whereas low carb advocates can consume as low as 10-15%.
Technically, carbs are not an essential nutrient so we don't need to eat them to survive. With that said, going very low carb is simply unnecessary to reach your health and fitness goals.
The best way to arrive at your desired carb intake is to first establish how many grams of protein and fat you want to eat first, then the balance will be your carb intake. For example, if you are looking to cut some fat for the summer without losing muscle, you can intake 1 gram of protein per pound of body weight, 0.5 grams of fat per pound, and the balance will be carbs. For a 180lb man, that means 180 grams of protein and 90 grams of fat. Assuming a 2,000 calorie diet, that leaves 200 grams of carbs left over (1 gram of protein/carbs has 4 calories, and 1 gram of fat has 9 calories). The percentage breakdown in this example is roughly 35% protein, 45% carbs, and 20% fat.
As a general guideline, somewhere around 40-50% carbs, 25-30% protein, and 20-30% fat is a solid benchmark during a cutting program. You can play around with increasing, or decreasing the carb/fat level to see what works best for you. ”
