It sounds like you've got a pretty good plan, there, though the two "S" days a week might be a little much. And, are you watching your calorie deficit? At the end of the day, that's what counts the most. Since you asked, here is the strategy that I've used to lose 250+ pounds pretty painlessly:
Michael’s Weight Loss Plan
1) Zero tolerance for my “trigger foods” (candy, sweets, ice cream, bakery items and so forth).
2) 1500 “good” calories of “real food” a day (at least 1500 but less than 1600).
3) No soda at all, not even diet.
4) As little artificial sweeteners as possible.
5) Keep, on average, a 40/30/30 carb/protein/fat mix.
6) No trans fats, reasonable amount of other fats.
7) Limit sodium as much as possible (not easy!)
8) At least 100 grams of protein per day.
9) Limit simple carbs (white bread, white potatoes, sugar).
10) Some sort of exercise every day, even a short walk.
11) Weigh in once a week or less often.
12) Log EVERYTHING eaten into FitDay, every day, no matter what.
13) Have one “day off” a month. Nothing off limits except “trigger foods” and get right back to normal the next day.
14) As little alcohol as possible, save it for the “day off”.
15) Take whatever vitamins/supplements deemed necessary.
16) Don’t EVER give up!
Regards,
Michael
