Yes you can lose fat on a low carb because it’s just another low calorie diet. How do I know this? I’ve done low carb, (Atkins, etc) high carb, (Slimming Word) moderate carb etc and log my food and was shocked each time to see they were all low calorie. After the initial week or so the rate of fat loss is same as any other diet. It’s calories in calories out. Simple. It’s what some call indirect deficit diet placing silly restriction, rules can eat must eat etc. and of course you lose weight but nothing to do with low carb. It works because it’s a low calorie diet.
Some of the teas contain caffeine for an extra bolt of energy. More controversially is the inclusion of laxatives, which does help eliminate waste, but can have negative health consequences if consumed frequently. It’s true that our bodies naturally cleanse for us when it comes to the liver and kidneys, but when taken responsibly, weight loss teas further help move things along acting as a diuretic to flush out toxins and help us slim down when sipping before a workout.
