Losing weight is easy, keeping it off is hard.
Any method of diet, exercise, or whatever can be an effective way to lose weight. The issue is, that most people gain it all back, because the intervention eventually goes away or is simply unsustainable.
The only guaranteed way to lose weight and keep it off is lifestyle change. I used to have a 205 pound lifestyle. I did not exercise, I drank wine every day, and I would eat plentifully (though not over the top). An example of my 205 lifestyle was this:
1. wake up, eat bagel with butter and 2 coffees
2. drive to work
3. eat sandwich for lunch
4. drive home
5. eat a handful of nuts, an apple and banana
6. go on a walk
7. drink wine and play video games
8. eat a small dinner, usually rice, salad, and meat.
Doesn’t seem like a lot of food or too much excess, does it? However, compare it to my 185 lb and jacked lifestyle now:
1. wake up, drink milk and coffee
2. eat beef, bell pepper, brocolli, spinach, mushroom, and cheese breakfast
3. go to work walking
4. Eat beef, cheese, and mushroom lunch
5. go home after work walking
6. exercise, cardio or lifting, for 40 minutes
7. eat eggs, quinoa, beef, and brocolli dinner.
8. eat handful of nuts, apple, and blueberries
If you look at my diet side by side, the calorie amount is actually pretty even in both scenarios. My carb amount has decreased, and my sources of carb changed to those only of vegetables, fruit and quinoa. The biggest difference in this lifestyle from 205 and dad bod to 185 and jacked is that 1) exercise is part of my lifestyle and 2) alcohol is no longer part of my daily lifestyle. Again, it did not take a lot of change. However, changing those two primary parts of my lifestyle, and staying consistent for four years, is what it took for me to be here. Alcohol is something I do only socially, and no more than once or twice a week now.
Anyway, hope this helped some. Maybe write out what your lifestyle is now, and think about what might be your lifestyle 10 pounds lower and make those changes. Best of luck.
