Let me start off with this disclaimer first and formost. Im new to working out/eating healthy. Im in no position to give advise so I wont. I will just tell you my experience and you can take it for what it worth. Ill leave the advise giving to those who know what they are talking about,and ALOT of these folks on here smart.
I've battled weight issues for along time. I tried many times to lose it. I did ll the things I THOUGHT I was supposed to do. Cardio like a mad man and eating 5~6 small meals a day. It never wworked..why? Because I hated it. I hated cardio and I hated obsessing over my meals. 4 months ago I was told its about calories in vs. Calories out... and that being muscular helps you burn fat.
So instead of worrying about 5 or 6 meals I set my caloric intake at 2100 per day and used myfitnesspal to track it. I logged everything I put in my mouth.at first I didn't care where the calories came from as long as I stayed at or slightly under 2100,as time went by I realised that I was making healthier decisions as to what I was eating. Not long after that I was hitting my macros and eating all good healthy foods. I also started to lift weights. Just a simple push/pull/leg routine 6 days a week.I choose this because I was able to get in and out of the gym in bout 45 mins. It fit my schedule great. As a result I have lost 40 plus pounds in 4 months. With very little cardio. Just enough to warm up before my workouts and some extra alks and bike rides with my 3 sons.
It works. Just keep with it..
Im not telling you to not do cardio.(its great for you) im just saying getting the weight off is more important and that there are other ways to do it. Lift heavy,GET YOUR DIET IN CHECK and don't worry about your heart rate...
sorry to ramble. But your story sounded alot like mine. So I thought id share it.
