Let me tell you something that might shock you: most people are setting completely wrong weight targets. I’ve watched this unfold for years in gyms, online forums, and even medical offices.
Just last week, I overheard a conversation that made my blood boil. A woman was telling her friend she needed to lose 40 pounds because “that’s what the chart says.” The chart? Some generic BMI table that couldn’t care less about her bone structure, muscle mass, or lifestyle.
Here’s the brutal truth: random weight goals are why 95% of diets fail. But when you nail down your actual target weight goals using scientific methods? Everything changes.
The National Institutes of Health confirms that specific, measurable target weight goals increase success rates by up to 42% compared to vague intentions like “lose weight.”
Why Most Weight Goals Are Dead Wrong (And Dangerous)
I’m going to be blunt here. The fitness industry has sold us a massive lie.
Walk into any gym, and you’ll hear the same garbage: “I want to lose 20 pounds” or “I need to get back to my college weight.” These aren’t goals—they’re wishes based on nostalgia and magazine covers.
Real target weight goals require math, not emotions. And frankly? Most people are too lazy to do the calculation. They’d rather guess and wonder why they’re spinning their wheels six months later.
But you’re different. You’re here because you want answers, not fairy tales.
The 5-Method Framework That Actually Works
Forget everything you think you know about setting weight targets. These five approaches will give you rock-solid numbers you can actually achieve.
Method #1: The Backwards BMI Trick
This one’s pure genius, and 99% of people have never heard of it.
Instead of calculating your current BMI (boring), you pick your ideal BMI first, then work backwards to find your target weight. It’s like solving a puzzle in reverse.
Here’s how it works:
- Choose your target BMI (usually between 20-24 for most people)
- Plug in your height
- Let the math tell you your weight range
I watched a guy named Marcus use this method last month. He’s 5’10” and was stuck at 195 pounds, thinking he needed to hit 170. The backwards calculation showed him 154-185 was his healthy range. He picked 180 as his target and hit it in three months. No starvation, no misery.

Method #2: The Mirror Weight Strategy
This method sounds weird, but it’s incredibly effective.
Find someone with your exact height who looks the way you want to look. Not a celebrity—someone real. Someone you see at the gym, a friend, a coworker.
Ask them their weight. Seriously. Most people will tell you if you explain you’re trying to set realistic goals.
I know a personal trainer who swears by this method. She keeps a mental database of her clients’ stats and uses it to help new people set targets. “See Jessica over there? She’s your height and weighs 140. Is that the look you’re going for?”
It cuts through all the BS and gives you real-world data.
Method #3: The Performance-Based Approach
Here’s something most fitness “experts” won’t tell you: your best weight might not be your lightest weight.
This method ignores the scale entirely and focuses on what your body can do.
Pick a performance goal:
- Run a 5K without stopping
- Do 10 perfect push-ups
- Carry groceries upstairs without breathing hard
- Play with your kids at the park
Then track your weight as you train toward that goal. Whatever weight you are when you achieve your performance target? That’s your ideal weight.
A friend of mine used this approach training for a half-marathon. She started at 160 pounds, got obsessed with hitting 145, but realized she ran her best times at 152. Guess what her maintenance weight is now?
Method #4: The Body Fat Percentage Hack
Most people focus on total weight when they should focus on body composition.
Here’s the secret: aim for a body fat percentage first, then see what weight gets you there.
Healthy body fat ranges:
- Women: 16-24% (athletes), 20-28% (general fitness)
- Men: 10-18% (athletes), 15-22% (general fitness)
Get a DEXA scan, use a decent body fat scale, or find someone with calipers who knows what they’re doing. Once you know your current body fat, you can calculate exactly how much fat you need to lose to hit your target percentage.
This method prevents the nightmare scenario where you lose weight but still look “soft” because you lost muscle instead of fat.
Method #5: The Historical Data Method
This one requires brutal honesty, but it’s incredibly accurate.
Think back to a time when you felt your absolute best. Not when you were youngest, not when you were lightest, but when you felt strongest, most energetic, and most confident.
What did you weigh then? What were you doing differently?
I know this method works because I’ve used it myself. My “magic weight” is 165 pounds. Not because it’s the lowest I’ve been, but because that’s where I sleep best, recover fastest, and feel most like myself.
Your body has memory. It remembers what works.
The Biggest Mistakes Everyone Makes
Let me save you months of frustration by calling out the most common screw-ups:
Picking Someone Else’s Goal
Your sister lost 30 pounds? Good for her. That doesn’t mean you need to lose 30 pounds.
Your goal should be based on YOUR body, YOUR lifestyle, and YOUR health markers. Period.
Ignoring Your Frame Size
Not all 5’6″ women should weigh the same. Someone with a large frame and broad shoulders will naturally weigh more than someone with a petite frame.
Wrap your fingers around your wrist. If your middle finger and thumb overlap significantly, you probably have a small frame. If they barely touch, you likely have a large frame.
Setting Starvation Targets
I see this constantly: people picking the absolute lowest “healthy” weight on charts.
Just because BMI 18.5 is technically healthy doesn’t mean it’s healthy for YOU. Most people feel and look better somewhere in the middle of their healthy range.
Forgetting About Maintenance
Can you realistically maintain your target weight without becoming a hermit?
If your goal weight requires eating 1200 calories forever and exercising 2 hours daily, it’s not sustainable. Pick something you can live with long-term.
Putting It All Together: Your Action Plan
Don’t try all five methods at once. Pick the one that resonates most with your situation:
- New to fitness? Start with Method #1 (backwards BMI)
- Have fitness role models? Try Method #2 (mirror weight)
- Love challenging yourself? Use Method #3 (performance-based)
- Want precision? Go with Method #4 (body fat percentage)
- Been through weight cycles? Method #5 (historical data) is your best bet
Once you have a target, don’t set it in stone. Targets can evolve as you learn more about your body.
The goal isn’t perfection—it’s progress with purpose.
Common Questions (And Straight Answers)
What if my calculated target seems too high?
Trust the math, not your emotions. Most people have been conditioned to think they should weigh less than what’s actually healthy for them.
Start with the calculated target and adjust based on how you feel when you get there.
Should I tell people my target weight?
Hell no. Keep it to yourself or share only with people who support your goals.
Everyone has opinions about what you should weigh, and 99% of those opinions are worthless.
What if I don’t hit my exact target?
Targets are guidelines, not commandments. If you end up 5 pounds higher or lower than planned and you feel great, you’ve succeeded.
How long should it take to reach my target?
Plan for 1-2 pounds per week of weight loss, or 0.5-1 pound per week of weight gain. Add extra time for life getting in the way.
Slow and steady wins this race.
Can I change my target partway through?
Absolutely. As you get closer to your goal, you might realize you feel amazing 10 pounds heavier than you originally planned. Listen to your body.
The Bottom Line on Target Weight Goals
Setting target weight goals isn’t about perfection—it’s about direction.
Most people wander aimlessly through their fitness journey because they never took the time to figure out where they’re actually going. They just know they want to “lose weight” or “get in shape.”
That’s like getting in your car and driving without a destination. You might end up somewhere interesting, but you’ll probably just waste gas.
These five methods give you GPS coordinates for your fitness journey. Pick one, calculate your target, and start moving toward it.
And remember: the best target weight goals is one you can achieve and maintain without sacrificing everything else you care about in life.
