Thermogenic in my opinion is not going to solve your problem. You need to checklist yourself.
How long has it been since you took a break?
Do you re-feed?
What is your current diet and routine in detail?
What % of deficit are you in?
Ok I took a brake about 2 weeks ago for a whole week.
What does re-feed mean?
