The best time to begin a diet is on a Monday. Who in their right mind would start one on Friday? Hamburgers, pizza, hotdogs, chips and salsa. Friday leads right into a weekend of barbecue, homemade ice cream and root beer floats. Monday is a new beginning, a starting line, a chance to begin afresh. Starting a new diet on a Monday just makes sense.
And if you’re going to start a new diet on a Monday, you might as well start a new exercise plan to go along with it. Walking, pushups, deep-knee bends. It makes no sense to start a new exercise program on a Friday. Friday is the diving board into a relaxing weekend on the couch, watching the game. Any game. Multiple games. Let THEM sweat. It’s the weekend. A time to recharge your batteries. Starting a new diet and exercise program on Monday just makes better sense.
Unless of course you’re running late to work and only have time to tie your shoes and, “I wonder if there is any more of that strawberry streusel left? Yes, there is. A million calories per bite? No time to get all mathematical. I’ll eat it on the way.”
It’s possible to start a new diet and exercise program on Tuesday (the perfect day for second chances when Mondays don’t go quite as planned), but I wouldn’t recommend it. Starting on Tuesday is like lining up to race at the Indianapolis 500, but your car won’t start, and the others have already been around the track at least four times. You might as well pull it into the pits and try again next year.
Tuesday IS a great day to start making plans for a new start. Grocery list — fresh vegetables, fruit, beans are good, skip the chips and soda, eggs can’t hurt, lots of fiber-packed avocados. Exercise plan — morning stretches, lunges, plenty of squats and pushups, might need some new walking shoes and some sweat-wicking workout clothes. Online shopping will deliver it by Friday just in time for Monday. And this time I mean it.
Unless of course something unexpected comes up like your house drops into a sinkhole, and then your neighbors are all up in your yard asking, “So, what did you do this time? I told you not mowing your yard would have consequences. And NOW look at your sad, flabby, out of shape and homeless self. What a shame.”
If you really want to start a diet and exercise program off right, not only should you plan to start it on a Monday, but a Monday that just so happens to also be the first day of the month. Like Monday, June 1, 2026. That’s a double-whammy of good-starting vibes.
Unless of course you’ve already planned a cruise to the Bahamas, then never mind. A cruise is the LAST place you want to instigate a “Nope, I’ve had enough. I’m on a diet. And now I’m off to jog around the ship about 100 times. Want to join me?” plan.
As you can tell, I’ve been giving this too much thought.
But if you really want to start a new diet/exercise journey on the right foot, the triple-whammy of all whammies is to begin the adventure on the first day of a new year, when that first day just so happens to be a Monday. Not because of some New Year’s resolution gimmick that we both know never lasts (The next alignment falls on Monday, Jan. 1, 2029, which gives us plenty of time to procrastinate), but because we truly care for our health and fitness.
