✳If you intentionally seek out accountability, the program does not need to be exclusively online. You can find groups in your area that have work outs and in-person meet ups; sign up with a buddy, or find a personal trainer that will help you work with the program.
You'll love the recipes, some basic and some fancier, all relying on fresh, whole foods. No diet foods, no shake powders, no extra hidden costs. Okay, some of the food may cost more for a while if you're not used to buying lots of fresh, whole foods, but once you get into a groove (do you really need a different breakfast every day?) the costs mellow out a little and you've even got some opportunities to save money if you haven't been a great meal planner in the past (you also should be eating out less, if you're following the calorie allowances and food suggestions).
The mindset videos deal with everything from self-sabotage to choosing better take-away meals. The talks are very practical, if you're looking for advice. If you already eat well and know a lot about healthy food and fitness, they may seem a bit condescending; try and listen with an open mind and with the intent to glean something new out of each one.

The best place to get some inspiration and a bit of honest (albeit some negative) opinions, is the "posts by others" on the Facebook page. Members answer others' questions, and there seems to be some support crew occasionally as well.
