I know how you feel, but I think the most important thing I’ve learned so far from Matt is that health =/= weight necessarily. I’d much rather focus on trying to up my metabolism/body temperature and experience the great effects of having a high metabolic rate. Let’s be honest, wouldn’t it be great to stop the cold hands, dry skin, coarse hair, anxiety, brain fog, insomnia, and all that other crap that goes with a slow metabolism? If I gain weight and can no longer see my abs, but I’m happy and healthy as can be mentally and physically, then I’ll be beyond satisfied.
So yea, try focusing on overall health and not weight. There are even some studies that show being ‘slightly’ overweight is potentially healthier than being at an average weight. And I’m certain that it’s better than being underweight!
Best of luck :)
