You won’t really gain weight overnight so you’re not going to lose weight overnight this is a process it’s going to take time you might not be losing weight. You might be losing inches if you continue with your clean eating you will have success you just have to be patient. Eat to Live not live to eat.
It’s not a miracle shake, but let me tell you 310 shake combined with clean eating and calorie counting, you will lose the weight. I lost a total off 38 pounds in two months drinking 2 shakes a day one for breakfast one for dinner, a healthy lunch, and only using the treadmill. It’s been a true fact for myself and so many others. So maybe you might have lost but don’t see it for yourself or instead of pounds you might have lost inches. Good luck either way.
