i have the shakes for a treat, maybe twice a week as makes a nice change for breakfast especially when i dont have time to cook in the morning. Not sure if it has stalled my weight but i havent gained. Some people say it stalls them, others say it doesnt. I have been losing weight at a slow rate, probably because i dont eat enough carbs or cals a day. Im still in ketosis but im not induction anymore so i just low carb with what ever i want now, as long as i keep my carbs below 15g then im happy. Im losing maybe 1lb a week but have stalled quite a bit, im still yet to find out what is stalling me!
if you are induction then most people say to avoid the shakes and just have clean carbs!
