Suggestions for a solid diet to help be healthy and develop a six pack?
I’m not overweight. I weigh 145 pounds and am 5’7". I just want to find a good diet to live a healthy lifestyle, put on some muscle (not much; I have a lean figure), and lose the little bit of flab I have on my tummy. I really want my ab muscles to come through. I’m not looking for a quick fix, because I know there is none. Any diet plan recommendations? Some exercise tips would also be helpful. Thanks!

Ok diet-wise, consume 6-8 small meals a day, not 3 medium main meals.
For excercises, on your first week do situps-crunches-reverse-crunches-bicyclese-oblique crunches in sets of 10 for 20 minutes, no rest in between (helps you lose fat). Week 2 ramp it to 12 reps for 25 minutes. Week 3/4 do 20 reps for 25 minutes, week 5/6 do 25 reps for 30 minutes.
Is it hard? H*ll yeah, but stick with it.
for diet…
exercise
sweat
move your body
eat more vegies and meat
less ice and bread
drink lots of water
for abs
sit-ups is the best
