Hello,

You did well. For the weight problem, you have to know that our muscle tissue is heavy than fat tissue. Your muscle growing bigger means your body become heavier. For sure you did lose some body fat, you can't see the difference of your weight its because your muscle weight replacing your body fat weight. It is a good thing . I give you an example of my friend, before he start hitting gym & Diet. His weight was 62kg+moderate size belly, after 4 months, his weight reached 68kg. But, his body figure fill with 4-6 pack abs . 

No Drugs for me either . For Body fats burning tips ,  you can try HIIT(High intensity interval training). HIIT is a method of intense cardiovascular training that's proven to burn body fat effectively, It works well on Low Carbs diet. How to do it? > Start with moderate pace jogging with 2-5 minutes >  Do 10 x 20 seconds all-out effort sprint with 30/25 seconds slow pacing jog between > after finnish previous section, do 10-15 minutes slow pace jog to cool down. Other than HIIT, Fasted walking in the morning. How to do it? When you wake up have a strong cup of black coffee to help raise your cortisol levels and also provide hit of caffeine, both of which will help to mobilize fat stores for energy. Also take about 20g of BCAA( Branched-chain amino acid)to prevent muscle mass loss & counterproductive occur. After these do 20-45 minutes of power walk(easy huh?) 

Hoped it helps
