re: Post workout smoothie meAl Replacements

That smoothie recipe is not bad, but for your stated goal of loosing 15, it is probably too high in carbs/sugar.
I like
1. A lower calorie protien. You can find as low as a 20g/90cal split. I like musletech that comes with 24g/140cal/plus creatine mono.
2. I also work out in morning. I like 1% cup of milk for the carb replenish and taste.
3. PB2 powder 1tbs (23cals)
4. 1.5 cups of spinach/kale mix. It makes me more full, dark greens have tons of healthy shite, low in cals.
5. Ice
Once u loose weight u want add yummy stuff like granola and fruits.
This will have about 40g protien, 20g carbs, 4G fats.
