Also, have you considered holidays like Thanksgiving and Christmas eve?
Are you going to skip all those diners with your friends/family? If you plan to stay on the plan, you’ll probably will have to exclude yourself somewhat socially or the temptation will be to big for you to binge, especially if you want to lose 4 lbs/week.
Why would you suffer through that when there are much better options out there that will still allow you to reach your goal? Although it wont be at the end of this year, you will feel much better and even be able to enjoy your fatloss journey.
If you are in doubt on how to proceed with your training if you can’t do the Blitz, may I suggest following up with men’s physique? This is a very well balanced and fatloss targeted program that progressively builds up over 12 weeks in volume. But the increase happens ever so slightly and you’ll be able to handle the work because the progression is mostly one of reps and density. Only the last phase has a volume progression in the form of extra sets, but you don’t max out sets from week 1, the sets are added gradually over the 3-week period.
Stick to losing 1% average bodyweight loss per week. Maybe you could go up to 1.5% for the first 3 weeks but after phase 1 I would advise you to stick to 1%.
You’ll also be able to eat more calories than you do now and still lose weight effectively. You don’t need to skip on holiday meals if you plan your nutrition ahead. For example you could calculate your total weekly value of calories that you can consume to maintain your 1% weight loss goals and redivide them based on how much calories you think you’ll consume on holiday meals. It is a little bit of a guess I know, so give yourself a margin:
For example, let’s say your caloric intake for fatloss is 2500 kcals to lose 1% BW per week. 2500 x 7 (weekdays) = 17500 calories total to reach your weekly target. Now, if you know you’re going to have diner with family for Christmas eve on Saturday the 24th and you’ll guess that the appetizer, main course and dessert will be around 5000 kcals total, then subtract that number from your weekly calorie target → 17500 - 5000 = 12500.
The next step is simply to divide your 12500 calories over the remaining six days → 12500/6 = 2083 calories. This amount of calories is very manageable and you’ll still be able to enjoy having a great meal with you family and/or friends.
If you decide to use this strategy, you can expect to reach your goal within 13-14 weeks. So by the end of Januari or beginning of February, you’ll have succesfully reached your goal.
This is just one possible solution on how you could further approach your fatloss effort in a way that is much more sustainable and will get you better results both physiologically and psychologically speaking.
But it is your choice. If you insist on reaching your goal by Christmas, then go for it. Best of luck.
