Well done so far Hunni. Shakes alone are fine. Some VLCDs recommend to limit bars to one a day as they tend to be higher carb and calorie and can also reinforce bad habits for when returning to food. If you only like shakes then you’re good. You may eventually get bored and branch out through need
The weight does come off quicker when TSing and doing zero exercise. It’s great that you’re enjoying exercise and I would never advise against but do be careful. When carrying extra weight, the impact on joints is greater than normal and you wouldn’t want to get an injury that floors you for months.
Obviously do as you wish and what feels right for you but you should find TS done 100% will get you where you want to be and fast.
Good luck - you’re finding your feet and doing great
