Well I would take out the squats because squats are not good for fat thighs. Doing crunches and sit ups will loose weight a lot faster. When you will do crunches you will notice the difference daily. and crunches is not more of losing weight but tightening,which may be perhaps what you actually need sometimes when you tighten/flatten the stomach you will come to realize that's all you actually needed.
I do it and I'm okay, so you should be fine. Unless I'm some kind of freak otherwise it's perfectly safe to do ab crunches after eating. Of course all those after eating ab crunches could some day come back to haunt me. I could become crippled and have to spend the rest of my life eating out of a tube. I could be in serious danger. The world as we know it could be over!!! Anyway the answer to your question is yes, it is fine to do ab crunches after eating.
No. You need to have a very low body fat percentage to even see abs. Unless you accompany crunches with healthy eating and other daily exercises, you won't see much.
Why should we have healthy eating
I would use weight watchers. It's completely safe.
Doing crunches won't make you bloated, it will help burn belly fat and gain abs. Eating junk food will make you bloated and fat.
A major surgical operation to remove strips of stomach fat, liposuction, Ab crunches, or maybe buy the diet pills, or go on Jenny Craig's diet. However, all the things that do work (if you persist with them) have been ruled out by you in your question.
a healthy eating guidline is to show you how much of everything you need.
Doing crunches does not make you skinny. Eating less calories than you burn and being active (cardio exercise) will make you skinny.
by eating healthy
I've seen people who haven't done a single crunch in their while life but have a six pack abs. It's all in the diet. Pain of not eating is better than 1000 crunches then eating pasta after.
The only bad thing about healthy eating is that it suppresses your appetite's freedom.
Eating some insects are healthy, but most.. I dunno.. Probably dont try eating insects :PP
