Dieting is pretty simple.
Get a weighing machine and weigh urself everyday.

Eat less & exercise more to see 0.5kg drop per week. If it doesn't happen then eat lesser & exercise more.

Yes. It works.

More easy to follow, compared to Keto diet etc.

Whats so hard?

To exercise or to eat less?

lose weight is very general.
find out you want to lose water or lose fat or lose muscles.

Then do a slight deficit as i said earlier. You guys have to be realistic. You think the weight u lose in first few weeks is fat? Not even close.

Just lose 0.5kg a week. Don't have to follow sh!tty diet, don't have to worry cannot eat this and that, mentally & physically healthy although will feels weaker at deficit, no risk of losing tons of muscle, less stress, sleeps well, and many more benefits.

Try follow those diet and tell me how long you can stand. Does it benefit you in the long run? Congratulations if you get better body but most ppl gets fatter at the end due to crash diet.

Don't exercise too hard & put stress in your body. Eating less already give some stress mentally & physically. If you add hard exercise will give you even more stress, that's why some people couldn't do it.

My simple observation, if your lips dry most of the day mean you have stress your body too much. It should be approach slowly, without you realizing it. Eat normal but cut the portion, exercise easy to burn fat. Remember, your goal is to lose weight not to become body builder

to retain your muscle mass, need to get more protein.
it helps on muscles recovery faster after workout.

don't do too much cardio, you'll lose fat but also will lose your muscle.

This is not my method. This is how your body works. Science.

Consumed food is energy. You do activity uses energy. Extra energy not used will store as fat. Simple as that.

You eat 2,000kcal but used only 1,800kcal. You gain fat (200kcal will store as fat).

You eat 1,500kcal but uses 1,800kcal. You lose fat (your body will tap to your body fat as energy).

Easiest and sustainable way of losing fat is slowly change your diet and routine.

1. Cut down all snacks. If still not losing then.
2. Cut down all sugary drinks. If still not losing then.
3. Cut down eating portion. If still not losing then.
4. Cut down one meal of the day.

In short, eat less but not go crazy like totally starve yourself. Go stage by stage.

If you feel like sh!t and crave for food. Don't torture yourself. Eat but in small portion. Throw in cardio to burn those energy consumed. Take the stairs instead of using elevator. Go window shopping at night (walk as much as you possibly can). Go hiking or swimming in the weekend.

Not saying those diet doesn't work. It requires mentally strong ppl. I can tell you straight more than 95% will fail. Or maybe 99%. IDK.

p/s : kinda free these days so can comment alot. 

If you are already fit. Short high intensity interval help prolong fat burning after exercise too. This way, you will not put yourself into too much stress while still maintaining your muscle growth hormone

Usually you need to find balance with exercise. Too much will make you craving for more energy. Good luck to you..
