Your slimming teas don't work
Slimming teas don't make you slim

Some contain laxatives or diuretics

Laxatives cause diarrhea, making you poo a lot, this doesn't allow your body absorb nutrients-bad idea

Diuretics make you lose water, which can give the feeling of losing weight

Neither of these things have sorted out the main issue--excess fat

For weight loss to be sustainable, you have to lose the excess fat. Fat is stored from the excess nutrients. It's like a bank.

If you don't spend it, it will be saved.
Same thing with the body

These laxatives/diuretics in these teas can cause dehydration and your electrolytes may become imbalanced which can lead to more problems

Especially if used for a long time

You're not helping yourself, because you're not losing the actual fat, you're losing water weight instead

If you notice, the target for these teas are people who are desperate and want to lose weight as quickly as possible

The principle that as long as you take less than your body needs, your body will have to burn the excess

Work on your diet, what you eat and how much you eat

Want to lose weight?

Brown rice rather than white rice
Whole fruits instead of artificial fruit juice
Avoid soda and sugary drinks
Don't overdo white bread
Exercise, move around more
Get enough sleep
Get smaller plates

Make them habits
