Teacher Liu, I've been doing aerobics every day lately, but my weight hasn't changed. Am I exercising too little?

Not necessarily. Weight loss isn't only about exercise; what you eat is also very important. Many people say weight loss is 70% diet and 30% exercise.

But I sweat a lot after exercising. Shouldn't that make me lose weight?

Sweating doesn't mean you're losing weight. For example, after exercising for half an hour, a single cup of milk tea might replace all the calories you burned.

Ah, yesterday after my workout, I really did drink a cup of milk tea and ate a small cake.

So you can start by drinking fewer sweet beverages and eating less fried food and desserts. Eat more vegetables, eggs, fish, and some whole grains.

Then should I still exercise? I'm a little afraid of sweating for nothing.

Of course. Exercise makes your body stronger and improves your mood. You don't have to exhaust yourself every day though. Brisk walking, yoga, and stretching are all good choices.

I understand now. Tonight I won't order milk tea. After dinner, I'll go for a walk with my husband. That sounds much easier.
