You've scrolled through countless Reddit threads, seen the arguments, and you're still stuck wondering. Some say it's the only way, others call it a waste of time. The conflicting advice is exhausting. So, let's cut through the noise and give you a straight answer.
The answer to your search, "does counting calories actually work reddit," is a definitive yes, but only if you understand the simple math behind it. Your body is an engine. It requires a certain amount of energy, measured in calories, just to exist. This is called your Total Daily Energy Expenditure (TDEE). When you eat fewer calories than your TDEE, your body is forced to get that missing energy from somewhere else. It pulls it from your stored body fat.
This isn't a theory or a fad; it's the first law of thermodynamics applied to your body. It's called being in a calorie deficit.
Think of it like a bank account. Your TDEE is your daily spending budget. The food you eat is your income. If you consistently deposit less money (calories) than you spend, your account balance (body fat) will go down. It has to. There is no other option.
Every diet that has ever worked, from Atkins to Paleo to Keto, works by tricking you into a calorie deficit. They do this by eliminating entire food groups, which naturally reduces your overall calorie intake. Counting calories is just the direct method-no tricks, no forbidden foods, just math.

Track your food. See exactly what you're eating. Know you're in a deficit.
You've probably tried this before. You swapped fries for a side salad, soda for water, and white bread for whole wheat. You ate "clean" for a month and the scale barely moved. It's one of the most frustrating experiences in fitness, and it's why so many people give up and assume their body is "broken."
Your body isn't broken. You were just a victim of calorie density.
"Healthy" does not mean "low-calorie." This is the single biggest misconception that sabotages fat loss. Let's look at a few examples:
This is why counting calories works where "eating clean" fails. It forces you to be honest. It replaces vague concepts like "clean" and "healthy" with hard data. You can't argue with the numbers. When you track accurately, you see exactly why you aren't losing weight. It's almost always the hidden calories in cooking oils, dressings, sauces, and mindless snacking that erase your progress.
Counting calories gives you control. You learn that you *can* have a cookie for 150 calories, as long as it fits within your daily budget of, say, 1,800 calories. This freedom prevents the binge-and-restrict cycle that plagues most diets.

See your daily calories and watch the scale finally start to move.
Getting started is simple. You don't need a fancy spreadsheet or a nutrition coach. You just need a food scale and a tracking app. Here is the exact process.
Your TDEE is the number of calories you burn per day. A simple way to estimate it is to multiply your bodyweight in pounds by a number between 13 and 15.
Example for a 180-pound person who works out 3 times a week: 180 lbs x 14 = 2,520 calories. This is their estimated maintenance level.
To lose fat, you need to eat less than your TDEE. A sustainable deficit is 500 calories per day. This is aggressive enough to see results but not so aggressive that you feel terrible and lose muscle.
Using our example: 2,520 (TDEE) - 500 (Deficit) = 2,020 calories per day.
This 500-calorie daily deficit creates a 3,500-calorie weekly deficit (500 x 7), which is the number of calories in one pound of fat. You can expect to lose about 1 pound per week.
This is the step where people fail. You must weigh and track *everything* that passes your lips. Get a digital food scale for $15. It's the best investment you'll ever make for your fitness.
Track it all. The bite of your kid's sandwich. The creamer in your coffee. The oil in the pan. These things add up to hundreds of calories.
Your weight will fluctuate daily due to water, salt, and carb intake. It's chaos. Weighing yourself once a week is a recipe for disappointment if you happen to weigh in on a high-water day.
Instead, weigh yourself every morning after using the bathroom and before eating or drinking anything. Log it. At the end of the week, calculate the average. Compare this week's average to last week's average. If the average is going down by 0.5 to 1.5 pounds, you are on the right track. If it's not moving, reduce your daily calories by another 100-200 and repeat.
Counting calories has a high failure rate, not because it doesn't work, but because people make predictable mistakes. If you can avoid these, you will succeed.
No. Think of it as a temporary learning tool. Track strictly for 3-6 months to build an intuitive understanding of portion sizes and the caloric cost of your favorite foods. After that, you can transition to more intuitive eating because you've educated yourself.
Calories determine whether you lose or gain weight. Macros determine what that weight is (muscle or fat). For fat loss, prioritize hitting your calorie goal first. A good secondary goal is to eat 0.8-1.0 grams of protein per pound of bodyweight to help preserve muscle while you lose fat.
The FDA allows for a 20% margin of error on calorie labels. It's not a perfect system. However, it's consistent enough. As long as you are consistently tracking the same (slightly inaccurate) data, you can still make adjustments based on how your weekly average weight is trending.
Don't panic. A one-week plateau is common and is almost always caused by water retention, not a halt in fat loss. Stick to your plan for another full week. If your weekly average weight still hasn't moved after two consecutive weeks, then it's time to reduce your daily calories by another 100-200.
You can, but it's much harder. A 30-minute run burns about 300 calories. It's far easier to simply not eat two slices of bread (about 200 calories) and not use that tablespoon of olive oil (120 calories) than it is to force yourself to go for a run every single day.
