I haven’t lost much weight since starting three weeks ago, but my jeans are growing bigger in the waist and people say I seem smaller. Am I hallucinating these changes? 
. I need to quit stressing about the scale!
It is possible to lose weight without noticing it. This occurs when you lose body fat while building muscle. Even if you lose inches, your weight may remain constant, indicating that you are making progress. Another reason scale weight isn’t so dependable is that it varies all the time. This does not happen. When you begin to lose fat, it is proportionate throughout your body, including your neck, waist, and ankle circumference. You’ll come out smaller yet with the same bodily shape.
I assume you mean that you are shedding inches around your waist rather than pounds of body weight.
If so, this is totally typical at specific periods in a workout regimen. It suggests you’re gaining high-density muscle and losing low-density fat.
Some people, particularly women who started with little muscular mass, gain weight while losing inches.
If you’re making improvement in terms of how much you can lift and how many reps you can do as you subtract inches, don’t be too concerned about your exact weight. When you’ve achieved the desired physical dimensions, you can then adjust your “goal weight” accordingly.
Yes, that occurs a lot! The scale is not the only way to assess fat reduction, and it’s still early days at 3 weeks. Some people experience a strong ‘whoosh’ early on, while others do not, due to a variety of variables. Your jeans are bigger, and you’ve dropped some weight! Well done! 
When I first started weightlifting, I went down a size in clothing, and people noticed within 5 weeks. There was no difference in scale, however.
It’s feasible that I gained over 20 pounds in a few months without growing my waistline by an inch; yes, I even gained abs and a V-Taper.
Basically, if you want to lose weight, you should reduce your daily calorie consumption and replace it with weight loss items like coffee to stimulate your metabolism.
So, cutting out refined carbs and sugar stopped your belly from growing but didn’t really accomplish much for your overall body weight because you never added any weight reduction foods such as detox water, coffee, or even green tea works here.
Muscle is denser than fat. Most likely, you’ll lose weight and increase muscle. This is normal.
When people exercise and diet, they gain muscle faster than they lose fat. This leads you to weigh more on the scale while looking more toned and slender. Muscles are heavier than fats. Fat is puffy like Styrofoam and floats in water. Muscle is denser than fat, therefore it sinks in water.
Well first, I suggest doing a little of everything like cardio, working out, dieting as well is very important. Also keep in mind the process doesn’t seem as quick as it looks, it’s much easier for people who are already skinny or with low metabolisms to look more built. Also you need to learn to balance everything, like don’t just do weight lifting or just run, you need to do a little bit of everything and do one more rep or a little more than you did yesterday, because it’s will all add up.
Either you are getting taller or you are shedding fat! Protein weighs more than fat; it makes you stronger and slimmer. However, if you exchange fat for muscle, you may not lose weight. That is healthy.
Maybe there is another option, but that’s all I know!
Congratulations.
You are gaining muscle.
And, after all, you’d have wanted to lose weight to look slimmer, not to weigh less.
Don’t be disappointed by the weight on the scale.
Begin relying on how loose your clothes feel.
How the measurements on your body have changed.
You’re shedding more inches than pounds on the scale, therefore you’re progressively decreasing fat. Your body is more efficient at using fat as an energy source than glucose. Continue as is.
Consume adequate proteins and fats to avoid muscle loss and energy depletion.
You are gaining muscle. Muscle weighs more than fat, so you can lose fat and inches while remaining the same weight, or even gain weight. Pay attention to your body composition, body fat percentage, and how you feel, rather than the numbers on the scale.
Trust me, I’ve lost over 100 pounds and only had success when I stopped stressing about the number on the scale.
