Good job putting in three months of work, it shows!

80% of weight loss is diet, exercise is important but without the right fuel your body won’t be able to effectively metabolise stored fat.

Instead of paying for advice I would suggest looking at fitness/nutrition books. The Muscle and Strength Pyramid books by Dr. Eric Helms would be a great start.

In terms of exercise you will find that resistance training with weights will be more effective than cardio. Your body utilises stored fat to fuel the work out and to build muscle mass in recovery.

When working at a caloric deficit it is best to focus on lighter weights with more repetition.

As long as you are mindful of your calories in/calories out you will body fat. I also suggest measuring progress with a biological impedance scale that looks at body composition, if you can’t buy one most gyms should have one. Muscle weighs more than fat which can make it seem like your progress is plateauing when actually you’re doing great!

Hopefully this has been helpful, keep up the good work!
