If you are physically capable of exercise, then use weight training AND cardio to increase your calorie expenditure, so you can still have a calorie deficit, but at a higher food intake (also known as a «high energy flux» program, or as we like to say in Burn The Fat, «eat more, burn more.»)

Using the concentration vs forcing data from Hansen 2005, and Hansen's value of 9.27 for Fi for 4xCO2, I derived (with high order accuracy, since it is not log - linear) the forcing vs time profile for the 1 % p.a. experiment, and then used this to predict the temperature and net flux evolution of the 1 % p.a. experiment.

Within a continuum of material (ie not at TOA, but within the atmosphere), temperature generally varies continuously (at least if you are willing to use high enough resolution, so this should tend to apply to the surface as well), so a pair of oppositely directed fluxes will both eventually saturate, and at that point they will be the same, so that there is no net flux (assuming the optical thickness is also distributed continuously; net fluxes can persist where there is a transparent gap, for example (such as at TOA)-RRB-.
