Are you talking about a meal replacement milkshake? If you make your own low-calorie milkshake, you can be sure, but you should also eat less. I'm also losing weight now. I slowly control my appetite, eat about one-third less every meal, then take a brisk walk for an hour every night, massage my thighs more before going to bed, but I still lost a few pounds, hehehehehe, personal experience, handmade, copy and paste, please don't come.
