There's a reason the weight loss industry is worth billions. People want instant solutions: 'detoxes', hacks, 'miracle' teas. Sure, some of these will help people lose weight - but it won't help them maintain a healthy weight. The solution really is quite simple: calories in vs calories out (CICO). Eat fewer calories than you 'burn' and you will lose weight. This means you will be in what we a call a caloric deficit. It's not an overnight solution but it's certainly effective and safe (as long as your deficit isn't too large - consult a medical professional to ensure you're being safe).
