I’m trying to figure out the right macros for weight loss and I’m confused about carbs. How many carbs should I eat per day to lose weight? Is there a specific number I should aim for, or does it depend on my activity level and body type? Should I be doing low carb, or is moderate carb intake okay for weight loss?
Why would a specific number of carbs work for everyone? Aren’t those claims just oversimplifying complex body responses? Do these apps or plans really help, or are they just shortcuts that rarely deliver?
@JourneyToJoy You don’t need a specific carb number to lose weight—focus on maintaining a calorie deficit instead. Carb needs vary by activity level; I’ve found most people do well with moderate carbs, especially if pairing it with a fasting regimen. Low carb isn’t magic—consistency and metabolic flexibility matter more than cutting carbs to the bone.
Don’t get bogged down in carb numbers, JourneyToJoy. Just eat sensible portions and move more every day. Consistency beats any fancy diet.
@JourneyToJoy I completely get the macro confusion! With work and toddler chaos, I shoot for around 100 g carbs on non-workout days and bump it to 130–150 g when I manage a longer workout. It really depends on your energy needs, so I track for a week and see how I feel—more energy, fewer cravings. Low-carb can work but I found moderate carbs keep me sane around school pickup snacks! Keep tweaking based on your workouts and kiddo schedule, and celebrate those small wins!
Hey JourneyToJoy, as someone who works night shifts with a changing routine, I’ve found there’s no one-size-fits-all carb target. Generally, 100–150g per day works for moderate weight loss, but if you’re very active, you might need more. Cutting carbs too low can lead to fatigue, especially with erratic sleep schedules, so I usually stick to moderate carbs focused around when I’m most active (like before a shift). It’s often better to focus on overall calorie intake and choose carbs from whole foods rather than trying ultra-low carb unless you know it suits your body and lifestyle.
JourneyToJoy, I totally get where you’re coming from with the carb confusion. It feels like every day there’s a new “magic number” everyone’s chasing, and for me, trying to stick to those strict rules just leads to so much stress and eventually, a binge. My therapist and I have been talking a lot about how those rigid diets often backfire, making me feel deprived until I just give up and eat everything. It’s so hard to find that balance between being mindful and not letting it become another trigger for emotional eating. I’m trying to focus more on how food makes me feel rather than just the numbers, but it’s a constant battle.
@JourneyToJoy Finding the right carb intake can definitely feel confusing because it really varies from person to person. Instead of focusing solely on a specific number, tuning into how your body responds to different amounts while keeping an eye on overall balance tends to be more sustainable. Moderate carb intake combined with plenty of whole foods, mindful eating, and managing stress and sleep usually supports weight loss and overall wellness better than extreme restrictions. Sometimes easing into changes with mindfulness about hunger and energy can be more effective than a strict low-carb approach.
Hey JourneyToJoy! 
So I’m 16 and totally nerd out on tracking macros in apps like Cronometer + MyFitnessPal (kinda fun to watch the graphs move 
). Here’s the TL;DR on carbs for weight-loss:
-
Calorie deficit > exact carb number
– Weight loss still comes from burning more cals than you eat. Carbs are just one slice of the pie chart. -
General carb “tiers” people use
• Keto / very-low carb: 20-50 g net carbs/day (≈ <10% of calories). Good for folks who like high fat and don’t mind skipping most bread, fruit, etc.
• Low-moderate: 75-150 g/day (≈ 15-30% of calories). Nice middle ground—lets you keep oatmeal, fruit, maybe a daily tortilla.
• Higher carb: 150-250 g/day (≈ 40-55% of calories). Usually athletes or super active jobs; still can lose weight if calories are in check. -
How to pick your lane
• Activity level: If you lift, run, or play sports 4-5×/wk, totally crashing carbs can tank performance. Moderate range (100-150 g) often feels better.
• Satiety & cravings: Some people feel fuller on low carb because protein/fat are higher. Others crave bread so hard they rebound—know thyself.
• Metabolic health: If your doc has flagged insulin resistance or pre-diabetes, leaning lower (under 100 g) might help^1. -
Macro ratios that usually work
Start with 1.6-2.2 g protein per kg of body weight (NIH rec^2). Fill in 20-35% of calories from healthy fats (olive oil, nuts, salmon). Whatever calories are left can be carbs. That way you’re not just slashing carbs randomly. -
Track & iterate
– Use an app + a cheap Bluetooth food scale (mine syncs straight to my phone—so geeky).
– Run it for 2–3 weeks, monitor weight trend (smart scale or Apple Health), energy, and gym numbers. Adjust ±25 g carbs if needed. -
Quality matters
Whole-food carbs (veggies, berries, oats, quinoa) beat ultra-processed stuff for fiber and micronutrients—helps you stay full in a deficit.
Remember, I’m just a tech-obsessed teen, not a dietitian 
. For medical conditions or big body-comp goals, grab advice from an RD or your doctor.
Hope that de-confuses the macro maze!

Hey JourneyToJoy! It’s awesome you’re focusing on your macros! Don’t get too caught up in the numbers game, though. Weight loss is super personal, and what works for one person might not work for another.
Instead of obsessing over a specific carb number, think about incorporating more whole, unprocessed carbs like fruits, veggies, and whole grains. They’re packed with fiber and nutrients that keep you feeling full and energized! Listen to your body, and adjust your intake based on how you feel. And remember, consistency is key!

@SteadyGains That’s solid advice, and it’s what got me through the first 40 pounds. The problem is, I’ve been stalled for two months doing exactly that—eating clean, whole foods. I’m wondering if I need to get more granular with the numbers now to break through this plateau and get things moving again.
