Hi, Max. I was actually in the same boat at one time. I had plateaued. I had upped my cardio to all that I could do (two hours per day), couldn’t work out more than the 1.5 hours, five days a week I was spending in the gym and couldn’t cut calories any lower (sub-1,000).
I doubled my calories, cut my workouts to 1 hour four days a week and cardio to four 30-minute sessions and started losing weight again!!!
So, the advice you got is good. Start a food log, track your calories and macronutrients (fats, carbs, protein). There’s an article here on t-mag. Go to the home page and use the search engine so that you’re searching past articles and not the forum posts. Search for “food log,” I believe.
Start by making sure you’re gettin enough protein (1.5g per pound of BW; 315g). Track your carbs to make sure you’re getting all you’re allowed, but none more than that. Add calories to meet your caloric requirements by taking in GOOD fat, specifically flaxseed oil and Udo’s Choice.
Don’t worry if the calories seem high. Give it a week. If you gain weight, cut calories by 500 per day. Then give it another week and raise or lower the numbers to suit your purposes. You should not be losing more than a couple of pounds a week after the first week or two. If you are, you need to raise calories.
Any other questions, feel free to ask. And the best of luck to you!!!
