Of course I would love to help you. Please keep in mind that I am not a professional and this is my own advice.
What I can say on the topic of depression is that it’s hard to stay motivated. Even somebody who does not suffer from depression has a hard time finding motivation at times. Let’s face it: we all have days where we skip the gym, lay in bed, and eat an entire jar of peanut butter while watching Captain America or any other Marvel movie.
The best advice I can give you is to do it the healthy way. What does healthy mean? It’s different to everyone. For somebody with depression, I’m proud of you for wanting to better your health. Remember that health comes before weight loss.
My personal motivation comes from knowledge. I know what good food does for my body, and I continue to consume it because I feel better and look good doing so. But, again, I skip the gym more than I’d like to admit and can eat an entire row of Oreos in one sitting.
Weight loss comes from you eating less than you burn in a day. THIS DOES NOT MEAN EAT AN EXTREMELY LOW AMOUNT OF FOOD. Bodies need fuel, and you deserve to eat. I don’t count calories anymore, but when I tracked, I was eating 1700 (or more) on rest days, and more than that when I’m lifting or doing cardio. A good starting point is to do a Google search on BMR and TDEE. If you still don’t understand after doing research, send me another ask and I’ll explain it a bit better.
Also remember: sleep is important, water is important, and nutritious food is important. This is a lifestyle change. These are habits you can maintain forever. Try to avoid being obsessive.
Consume food. Do not let it consume you.
