I joined a gym about 2 months ago, I do a lot of cardio and weight lifting to tone up. Been using Muscle Power (protein powder) Beast Creature (creatine) totally changed my eating habits. I eat a very low carb diet maybe 30g tops because you do need carbs but only the good carbs. A lot of protein such as meat, red meat a few times a week salmon and shrimp a few times a week and chicken. I'm also eating HIGH FAT, not low fat, no fat, or 2% fat. My favorite snack is Dairy Gold HIGH FAT cottage cheese with the soft chewy bacon bits and Pico De Gallo all mixed up, just throwing that out there. Anyway in just a few months I've gone from 245lbs to 209. So basically a good carb but low carb high fat diet and some hard word works for me and is paying off very well. Doing some running, planks, burpies, kettle belles, crunches what ever cardio and stomach exercises I can do for my gut is my main focus along with my upper body.
