Protein & Weight Loss: Why the Right Amount Matters
Protein plays a key role in our body function, and it’s an important macronutrient to pay attention to during health and weight loss journeys. Protein helps control hunger, stabilizes blood sugar, and helps preserve lean muscle as you lose fat. But contrary to what some influencers would have you think, more isn’t always better—especially if you’re eating well above your needs. Too much protein can stall your weight loss efforts, and even strain your kidneys!
One common mistake we see in weight loss is calculating protein needs based on current body weight. If you’re overweight or obese, this can result in consuming far too much. That’s why using your ideal body weight (IBW) is the safer and more effective approach.
Why Use Ideal Body Weight to Calculate Protein Needs?
Ideal body weight reflects what’s appropriate for your height and frame—not your current weight. Using it ensures you’re giving your body enough protein to support metabolism and muscle without tipping into excess.
Over Consuming protein doesn’t just slow or stop your weight loss goals —it can also lead to:
- Strain on your kidneys
- Slower fat loss
- Bloating and digestive discomfort
- Dehydration
How to Calculate Protein Needs Using Ideal Body Weight
A good general rule to calculate Ideal or Healthy-Goal Body Weight:
Eat 0.7 – 0.8 grams of protein per pound of ideal or healthy-goal body weight per day.
Step-by-step example:
Let’s say you’re 5’5” tall and your ideal body weight is 130 lbs (Check with your provider to find YOUR ideal body weight!)
- 0.7 x 130 = 91 grams of protein/day
- 0.8 x 130 = 104 grams of protein/day
-> Recommended protein range: 91–104 grams per day
If you’re not sure what your ideal body weight should be, we can help you calculate and customize it for a metabolically healthy weight for you during your visit or virtual consult.
Best Protein Sources for Weight Loss
Once you know your daily target, aim to divide your protein intake throughout the day. Choose lean, high-quality, and whole-food sources like:
- Eggs and egg whites
- Chicken or turkey breast
- Tofu or tempeh
- Low-fat Greek yogurt
- Fish like salmon or cod
Supplementing to achieve your daily protein intake goal with a clean protein powder, or healthy protein bar is a fine strategy, within moderation. Pairing protein with fiber-rich veggies and healthy fats will further stabilize blood sugar and support steady weight loss.
Watch Out for Overdoing It
More protein does not equal faster results. In fact, consuming significantly more than your ideal weight calls for can backfire—your body WILL convert excess protein into glucose through a process called gluconeogenesis, which can spike insulin and slow fat loss. It also places added stress on the kidneys, especially for those with underlying kidney issues.
